technical excellence
Our new teleprinter runs so quiet
we had to fake a little noise.
Operators couldn't get used to the eerie quiet of the keybOard on our
new TermiNet 300"teleprinter.
So we added a little noise to give them some "feeC' Even then
it's quieter than an office typewriter.
And when it's running as a high-speed printer from tape or
computer it's quieter still.
A front-panel switch lets you select a speed of 10 characters per
second. That makes it compatible with the leading communications
terminal. Or a speed of 15 characters per second. That makes it
compatible with the leading computer terminal.
Or its unique speed of 30 CPS . Which makes it compatible with
your special requirements of data handling, and saves you money.
But quietness and speed aren't all. We've built a whole raft of
versatile features into the TermiNet 300 printer. That way it'll take
care of your needs for years to come.
Things like horizontal or vertical tab. Long-print lines- up to
118 characters. Pin feed. A transparent mode. Remote 20-character
answerback. Parity check. Full/half duplex operation. And many more.
Most of these options are supplied as simple modular plug-ins.
Which brings us to the reliability of modular construction. It's
very rellable. And that's backed up by General Electric's nation-wide
service. A point worth considering. And considering again.
Whatever your needs-time sharing, information systems,
computer-outputed editing and formatting , even just repetitive
printing-the TermiNet 300 teleprinter is what you should specify
in your present system. Or in your next. General Electric Company,

The widespTead use of telephone lines to tmnsmit computer data and the ability
to connect non-Bell equipment to such lines has effected a large increase in the numbe1' of modems and multiplexers available fTOm independent manufacturers, This

AND IN THIS CORNER, . . . . RCA
In announcing their new family of compute-rs, RCA predicts that they will have a billion dollar computer business by the late 1970's and will be number two. Guaranteeing a set conversion cost with a daily late penalty clause, RCA is attacking the
very hem"t of IBM's empire. As one of OUT C01nmentators states in this issue, it will
take plenty of money, knowhow, hm'd work, and thousands of hungry salesmen.

LETTERS TO EDITOR
To the Editor:
Your column in the April, 1970 issue
of MODEI~N DATA "vas entitled "Data
Base Systems" and discussed the
CODASYL Data Base Task Group
report on data languages. You
stated that "At least two manufachirers are now buiHing systems to
simulate the structure suggested in
the CODASYL report."
I would appreciate it if you
would identify for me those manufacturers who are implementing or
have implemented the CODASYL
report.
Byron W. Krause,
A C Electronics,
Div. of Gen. Moto.rs,
Milwaukee, Wise.
The Author's Reply: Thank you for
your Sept. 18 response to my April
Data Base article. If I could catch
up to the point of being only 6
months behind in my reading, it
would be a great improvement.
In answer to your question on
implementation of the CODASYL
data base structure, the two manufacturers were GE and Univac. GE
had announced its IDS system, but
I don't know what has happened in
the shuffle. Univac made its official
announcement at an ACM symposium in N. J. To the best of my
knowledge Univac is following up.

operations in Tijuana, Mexico.
M. C. Langdon,
Project Manager,
Dept. of Water Resources,
Sacramento, Cal.
The Author's Reply: As the old response goes ''I'm glad someone
asked that question." Seriously
though, I received the same question when I went over this example
at our Sou'rce Data Automation
Semina?' a few weeks ago in New
York City. My response was to ask
several members of the audience
what keypunch stTOke mtes were
obtainable at their installations.
The answers varied all over the lot
(e.g., 5000-12000 strokes per
hour). Our discussion revealed
that stroke rates depended on such
factors as the quality of their operators, the type of data they were
inputing,
operator
motivation,
physical environment, etc.
The exact words utilized in our
Septembe1' SDA column were as
follows: "
6500 stTOkes per
hour is the average rate of my keypunch operators on my type of input data." I have underlined the
word "m y" where it appears to emphasize a point. That is, use live.
operational data where possible in
any keyboard entry cost calculations. What (Toad is it to use a
national standard for keypunch
rate when your operators pTOduce
at a different rate? The figure of
"6500 s17h" was obtained fTOm a
client of ours for whom we tcere
performing a study of data entry
devices and their relative costs. He
was concerned with obtaining as
accurate (not average) cost figure s
as possible. I can only reiterate
that the figures used in our column
were determined by actual experience and were not intended to
be those of the average installation
( if there is such a beast ) .

If your office needs to take or send information up to
1200 words per minute, we have a way.
Our Dataspeed(i\l Magnetic Tape Terminal.
It bridges the gap between low-speed keyboard preparation and high-speed on-line data transmission .
At the same time it reduces the cost of data transmission over regular telephone lines.
The data that is sent and received is recorded on a
compact cartridge that has a capacity for 150,000 characters. And the tape is reusable once the information on
it is no longer needed.
Besides communicating at high speeds, the terminal
has a Forward/Reverse mechanism that can search for
specific data on the tape at a rate of 4,000 characters per
second.
And time-consuming correction procedures are cut
to a minimum since individual lines or characters can be
easily located and corrected within a message.
The terminal can be adjusted to answer calls automatically, too . Transmission can be sent and received over
regular telephone lines (Data-Phone®service) or private
line service.
Often at low-cost after-hour rates.

systems to make our packs at a competitive price. And that was tough.
CDC inspects each pack at every stage of manufacturing and four times when it's
assembled and ready for shipping. We do the quali ty control so the customer won't have to.
Add to all that special care the professional after-sale service and back-up we provide.
It does begin to seem a little strange about that pricing.
But that's our problem. Yours is how to get in touch and get our free booklet on what
we're talking about.

NEWS ROUNDUP
TWA, BURROUGHS BATTLE
Trans World Airlines announced that it has "discontinued all efforts to use a Burroughs Corp.
computer (for its automated passenger) reservation system and that it has instituted suit against
Burroughs . . . to recover damages in an amount
exceeding $70 million for misrepresentation and
breach of contract." The cancellation applied to a
B 8300 system valued at approximately $38 million. According to Burroughs, which has filed a
countersuit denying TWA's charges and asking for
$1l.5 million in balance owed and interest the
basic system was designed to TWA's specific;tions
and sold with the understanding that the airline
would develop its own applicational software. Burroughs said it first learned the suit had been filed
at the onset of a N.Y. meeting with TWA representatives after being advised by the airline that it
expected Burroughs to compensate them for losses
resulting from delays in the full operational use of
the system. TWA has already announced its intention to implement an advanced version of
IBM's PARS (Passenger Airlines Reservation System ) on S/360 Model 65 or 75 computers. Versions of PARS are presently in use by Eastern and
United Airlines.
JUSTICE DEPT. SUPPORTS NEW CARRIERS
The Justice Dept. has advised the FCC that it favors the licensing of new common carriers to compete against AT&T and Western Union in the microwave transmission area. The Justice Dept.
supported the new applicants' contentions that the
established carriers have not adequately responded to modern needs for specialized data
communications and that present telephone services were neither priced nor designed to meet
these needs.
NO LOVE LOST
American Telephone and Telegraph Co. asked
Federal Communications Commissioner Nicholas
Johnson to disqualify himself from participating in
FCC matters involving Bell System companies. In
22
a "petition for disqualification" addressed to the
Commissioner, AT&T characterized remarks Johnson made in a speech to the Digitronics Users
Assoc. Conference on Oct. 19 in Chicago as demonstrating "a deep-seated bias and prejudice
against the Bell System." Johnson's speech was entitled "Why I Am A Conservative 01' For Whom
Does Bell Toil?"
TWO NEW IBM COMPUTERS
IBM simultaneously announced two new computers: a lower-priced version (Model 6) of its System 3 computer; and a modular "sensor-based"
processor (System 7) for industrial applications.
The S/ 3, Model 6 is dcsigned for problem-solving
as well as commercial applications and is available
with up to 9.8 megabytes of disk storage; a BASIC
compiler; and a Model 2265 display. The l.5 usec.,
8 to 16K machine is primarily a stand-alone "office
computer," however, and is offered with a simplified keyboard /con trol panel and a choice of five
printers, including two with 22" -wide carriages for
ledger cards. Like the previously-announced
Model 10, the Model 6 is programmed in RPG II
and uses the 96-column punched card. Model 6
configurations will be priced from $1,015/mo.
(typical: about $1,600/mo.) and made available
in March, 1971.
The all-monolithic System 7 is basically a data
acquisition and control system which can be environmentally isolated for unattended operation in
difficult industrial and laboratory conditions. Capable of being used either independently or in
~onjunction with a larger, host computer, the S/7
IS so modular in design that it carries a base price
of $352/mo. - making it unquestionably IBM's
lowest-priced computer.
1975 MINI MARKET
Creative Strategies, Inc .. of Los Altos, Cal. predicts
nearly a 50% annual growth in sales of minicomputers and associated peripherals over the
next five years - reaching an annual level of $l.5
billion in 1975. The consulting firm pointed out in
a recent report that business EDP would eventually constitute the largest market sector, experiencing sales of $471 million during 1975. The
report also predicted that both CPU pIices and
the number of minicomputer manufacturers would
be reduced by more than 50%.

3 NEW ELECTRONIC MARKETING HANDBOOKS
A HANDBOOK ON MAR KET RESEARCH
This book was prepared specifically for the marketing
man who has had little or no formal training in market
research and statistics. It is meant to guide the manager
who must do his own market research or else do without. It is meant for the man for whom market research
is just one of several marketing responsibilities. It is
meant for managements who want usable information at
reasonable cost and minimal delay. It is meant for the
manager who will be buying outside services and wants
to get behind the specialist's jargon to a basic understanding of the art.
In fourteen chapters the manual covers . .. INTRODUCTION ... THE HUMAN NATURE OF MARKET RESEARCH ... THE USE OF SECONDARY
DATA . . . THE USE OF INTERNAL DATA ...
SURVEYS, BASIC CONSIDERATIONS . . . SURVEYS, QUESTIONNAIRE DESIGN ... COMPANY
IMAGE STUDY .. . EVALUATING COMPETITION
... SALES FORECASTING ... TECHNOLOGICAL
FORECASTING ... QUOTAS ... PRODUCT PLANNING . .. EVALUATING SALESMEN ... RECOMMENDED READING
The Handbook On Market Research For The Electronics Industry contains over 156 pages (8%" x 11", two
column, soft covers) . It is priced at $37.50. R eaders say
material of this kind is worth more!
A HANDBOOK FOR PRINCIPALS ON
MANUFACTURERS' REPRESENTATIVES
Other books have been written about reps. But those
were for the guidance of reps or propaganda in their
cause. This book fills a different need. It provides information and how-to advice for principals. No sponsoring association has censored out material beneficial
to principals at the cost of disadvantages to reps.
In thirteen chapters, the book covers ... SELLING TO
THE ELECTRONICS INDUSTRY . . . SALES
CHANNELS . . . COMPANY SALES FORCE OR
MFRS' REPS ... RECRUITING REPS ... MARKET POTENTIAL, TERRITORIES AND QUOTAS
· .. COMMISSIONS . . . THE CONTRACT . ..
SALES TRAINING ... FEEDBACK FROM REPS
· . . REPS AND INQUIRES ... GOING DIRECT
· .. THE REP'S IMAGE . . . THE FUTURE OF
THE REP.
Written entirely for the guidance of the principal and
advising in his interests, The Handbook For Principals
On Manufacturers' Representatives contains 85 pages
(8%" x 11", two column, soft covers). Now in the second printing, it is priced at $15.00.
AN ADVERTISING/PROMOTION HANDBOOK
This is not a book on how to write copy and purchase
graphics. It is a selective guide on how to get value for
your advertising/promotion investments. Though most
ad managers, ad agencies and trade publications will
find this book quite instructive, it was written for the
marketing manager who personally handles adve~tis
ing / promotion as one of several marketing functIons
· .. for marketing managers, as well as top managements,
who never handle advertising personally, but want practical criteria by which they can evaluate the claims,
recommendations and performance of their ad managers,
agencies and publications.
In nine chapters this book covers ... INTRODUCTION
· . . MEDIA SELECTION . . . INQUIRIES . . .
MEASURING ADVERTISING EFFECTIVENESS
· . . DIRECT MAIL ... PUBLICITY .. . AD AGENCIES ... TRADE SHOWS .. . ODDS AND ENDS.
An Advertising/Promotion Handbook For The Electronics Industry is not a rehash of academic texts and
dubious publication research. ALL of the material is
original. The manual contains over 165 pages (8%" x
11", two column, soft covers ) . It is priced at $30.00.

COMPUTERS FOR MAN
Relative to the increasing public concern for more
applications of computers to human welfare, this
year's Omaha State Fair provided a free lung
check-up courtesy of two Univ. of Nebraska Medical Center physicians, the Nebraska State Tuberculosis and Respiratory Disease Assoc., and a
Varian 620/ i mini-computer. An exhibit at the fair
invited visitors to fill-out a short questionnaire
("D o you smoke?", "D o you have a cold?", etc. )
and exhale into a bellows device. By comparing
this data with the data already in the mini's files,
the doctors were able to tell the visitors in 90 seconds whether or not there were indications of lung
problems that warranted furth er examination.
BIGGEST SIGMA

It lets you talk to your computer
without running your phone bills sky-high.
With our Frequency Division Multiplexer you can link your computer
and terminals with the least number
of phone lines.
And at the least expense.
It's the only FDM that has 20 rna,
60 rna, and EIA interfaces standard
in every unit. So it will interface with
any terminal or computer on the market-which makes it real off-the-shelf
stuff.
(That's one reason we can deliver
a system in 30 days and have it running on the 31st.)
Our multiplexer is really a set of
modems, each tuned to a different
frequency. We make 4-channel and
I -channel units. So it's easy to set up
an FDM system with the exact number of terminals you have at any
location.
And you don't have to pay for any
more equipment than you need.
At speeds of 110 baud, the system
can handle up to 18 channels on a
MODERN DA TA / Decembe r 1970
voice-grade line. It allows data transmission at speeds from 75 to 600 bps.
Once they're installed, there's no
reason why our FDM's won't work
forever. But if anything goes wrong,
we have a nationwide service organization that will fix the trouble fast.
You can lease or buy our FDM
system at very favorable prices. (One
of our customers replaced his old system with ours at a saving of $3000
per month.)
Ultronic runs one of the world's

CORPORATE NEGLIGENCE - The office of Congressman
Cornelius E. Gallagher (D ., N.J .) is being " deluged with
examples of indifference, carelessness, and incredible
arrogance on the part of those who are supposed to' run
computers in large organizations ." Congressman Gallagher
is sponsoring legislation " to relieve the consumer from corporate negligence in the use of the computer./I In a recent
announcement he stated: "There is an enormous legal lacuna surrounding the use of the computer which . .. may
inhibit the very real social and economic ben e fits which its
proper application can provide our Nation. Certainly the
Congress must begin to bring forth legislation which reflects the simple fact that business firms are misusing the
wonders of computer technology."
1971 TRENDS MIXED - Two U.S. Department of Commerce electronic compute r industry specialists believe that
"some persisting financial problems will probably inhibit
corporate expansion in 1971, and raising capital may be
difficult./I
"A poor 1970 earnings record and a dulled glamour
image for computer stock will make the equity market an
unsatisfactory medium for raising funds, while continued
high rates may restrain d e bt financing ." James N. Carr
and Stephen T. McClellan of Commerce's Scientific and
Business Equipment Division said .
Domestic shipments are expected by them to pick up 15
percent in 1971, but the international market will most
likely be a substantial growth market. Many U.S. computer
and peripheral equipment firms are expected to become
more international in character - i.e., more exporting and
establishing more foreign subsidiaries.
FTC RULE - The Federal Trade Commission recently proposed rules on credit billing practices which, according to
Senator Sam J . Ervin (D., N.C.), are "the first of many,
many steps needed to protect individuals from the abuses
of a computerized society. " He called on the Nixon Administration "to look to the beam in its own eye and show at
least as much initiative with respect to Federal computers
and dqta banks." While it is encouraging to see the FTC
"jumping on the bandwagon," administrative rules are no
substitute for comprehensive statutory protection which government agencies are powerless to rescind, ~mend, or ignore," according to Sen . Ervin .
HAZARDOUS NOISE - Sometimes programmers make errors because of high noise levels in computer laboratories
according to researchers at the National Bureau of Standards In stitute for Basic Standards. A recent study found
that "not only is the noise disruptive to concentration and
communication , but in some cases the level is sufficienly
high to cause permanent hearing damage." NBS recommended that computer personnel avoid noisy equipment.
Also they should have their hearing measured frequently,
and wear ear protection when the no ise level is too high
for normal conversation.
WWMCCS PROPOSALS - The Air Force has issued
requests for proposals to 17 companies for the replacement
and mode rnization of data processing equipment located
at the fixed headquarters of the World Wide Military Command and Control System, and related Intelligence Handling Systems. Proposals are due by Feb . 1, 19-71. The
Department of Defense plans to procure a minimum of 15
new standardized computers during FY 1972-73, with a
minimum of nine systems in FY 1972. Machine sizes will
range from medium to large. DoD warned that "if proposals result in prices exceeding $46.2 million from all proposers for the hardware and software for the 15 systems,
the government may re-examine its requirements, restate
such requirements, cancel or amend the solicitation and
resolicit proposals for its requirements."
GAO DP CENTER - A Data Processing Center (DPC) has
been established in the Government Accounting Office
(GAO) . The center will, among other services: (1) Provide
EDP services, including equipment operation, systems
analysis, design, documentation, and programming to all
organizations in the GAO ; (2) Develop and maintain an
integrated management information system for GAO; (3)
Evaluate existing systems and procedures for the purpose
of recommend ing specific application of computer-based
systems and subsystems; (4) Conduct EDP project feasibility
studies, developing project specifications and administering
projects; (5) Advise on the acquisition and disposition of
EDP equipment.

COMPUTER BUYING The Bonn Government in
Germany is acquiring computers. In late 1969 it had
some 150 computers in operation. Since then, the
number has risen to 174 with another 86 to be delivered before the end of 1970. Plans beyond 1970
call for still more electronic brain s, according to the
Journal of Commerce . It is estimated that soon the
government will have a staff of 6,000 to operate the
computers. The biggest sin gle computer user is the
Federal Postal and Telecommunications Office with
43 machines. The Transport Ministry has 41; the
Ministry of Economics has 10; and the Ministry of
Interior has 7.
CANADA'S ROADS - Computer systems help engi neers in the Canadian Department of Public Works
to design and build national park roads. A contract
has been given to Spartan Air Services Ltd. to pro duce "orthophotographic maps," from aerial photographs. The computer automatica lly reads the photographs and produces information which will assist
the engineers in road routing.
FAVORABLE OUTLOOK - The U.S. Department of
Commerce 's Bureau of International Commerce believes that the Canadian market looks promising for
U.S. EDP sales. Favorable factors are: the Canadian
economy's projected average annual growth rate of
5% through 1973; sl ac k competition in the EDP
market; a stimulating effect on imports as a result of
the Government's deci sion to " float " the Canadian
dollar. U.S. firms now supply about 93 percent of
Canada's total EDP imports.
E. EUROPEAN EXPORTS Among the principal
commodities licensed for export to Eastern European
countries by the U.S. Department of Commerce in
the second quarter of 1970 were computers and
peripherals ($5 .5 million, including $1.6 million to
the U.S.S.R. , $1.1 million to East Germany, and
$0.9 million to Czechoslovakia).
COMPUTERS FOR SHIPPING - The Panama Canal
Co., a U.S. Government agency, is considering computerized controls for its 50-mile waterway. Computer Sciences Corp. has been awarded a contract to
study the possibility. It is believed that with computerized information traffic capacity and consequently
toll revenue might increase. The study report is due
by May 1971.

TOOLS OF REPRESSION Computers could become a horrifying tool for prying and repression, a
group of international lawyers warned recently. At a
Brussels meeting sponsored by the prestigious
Council of Europe, the assembly expressed fear
about technological threats to civil liberties, such as
data bank s, hidden microphones, and infrared cameras . In the conference's conclusion the lawyers
said: " New threats to the individual and his private
life have arise n out of modern techniques. The computer, which is unversally recognized as a magnificent instrument for management and data process ing, can, in the hands of unscrupulous authorities
become a horrifying tool for prying and repression."
ISRAEL MARKET U.S. Department of Commerce 's Bureau of Intern ationa l Commerce forecasts
rapid expans ion of Israe l's EDP market. This growth
is expected as the result of a booming economy and
a determined effort to maximize efficiency. Civilian
EDP, now valued at about $13 million, is expected to
advance about 30 percent a year. Imports have furnished almost all of Israel 's EDP market. Local output, while small, is growing and is largely directed to
export. Numerous small computers are being exported to Western Europe. About 40 percent of Israel 's imports come from the U.S., with the rest
coming from firms in Germany, France, and the
United Kingdom . Virtually all the firms are American-backed.

A. Eisenstat; Michael Roth; Arthur I. Sarnoff;
Daniel Rosenbloom; Mark S. Handler.
DIRECTORS:
United Data Centers, Inc. is a network of commercial data processing centers. It
was incorporated in 1967; ownership becam e public the following year. Since its inception the company has acquired six data centers as well as
Sports Data, an organization specializing in computerized golf handicapping and billing for country clubs. UDC is currently operating at an
annualized rate of $3)~ million. UDC has a uniqu e
marketing philosophy which emphasizes relatively
small metropolitan areas where need is considerable, but where competition has not developed
to th e level of larger areas. Also, UDC prefers to
expand through acquisition of ongoing businesses.
BACKGROUND:
share, up from a loss of ($0.05) for the similar
period in 1969. Operating revenues for the same
period were $1,386,423, up from $865,347. Figures
for the six months ended 6/30/69 have been adjusted to eliminate loss from a subsidiary sold on
12/31/ 69.
OUTLOOK: United Data Centers, Inc. is forecasting
continuin g profitability for the two remaining
quarters of the year, which will be the best year in
th e company's history. UDC is in a strong cash
position, has no debt, and is continuing its
acquisition program as well as the development of
new proprietary computer packages. UCD is the
only company concentrating on secondary and tertiary markets . In addition to growth via
acquisition, internal growth substantially exceeded
industry average growth rate of 13%in 1969.
Corporate offices are located in Greenwich, Connecticut. Data centers are located in Salem and West Springfield, Massachusetts; Syracuse, New York; Birmingham and D ecatur,
Alabama; Benton Harbor, Michigan; and Miami,
Florida.
FINANCIAL SUMMARY: The following statement of
earnings depicts consolidated results of UDC's operations for two years ended D ecember 31, 1970.
Also shown are comparative interim statements for
the current and prior reporting periods.
PRODUCTS /SERVICES: The product line includes industry-oriented application packages and several
proprietary program packages of a classical nature
(e.g., accounts receivable, payroll ). Considerable
emphasis has been given to marketing Computafuel, UDC's unique proprietary computerized service for th e fu el oil distribution industry. The
company is the leader in servicing this industry.
More than 300,000 h omes ( i.e., 2% of U.S . total )
are beated with oil burners monitored by Computafne!' Complementary systems are under development and will be introduced shortly.

MODERN DATA/ December 1970
Much of the
software
for the new
PDP-S/e
is 9000
computers old
It was 1962. John Glenn became the first U.S. astronaut to orbit the earth.
West Side Story won an Oscar as best picture of the year. Hemlines reached almost to
the knee and were still rising.
That's when software for the PDP-8/e was begun.
Two years later, we introduced the world's first minicomputer, the original PDP-8 with
teddy bear. Since then, we have created, extended, and polished the software that works on
all 9000 PDP-8 family computers-computers that control blast furnaces, monitor
nuclear reactors , analyze electrocardiograms, perform all kinds of process and machine
control functions. Software for the PDP-8/e rea Ily works , and much of it has been
working for a long time. On the other hand, much of it is brand new. DIBOL - DIGITAL's new
business oriented software. PS-8, the new device independent programming system.
And lots more. All together, old and new, there's an awful lot of it.
The PDP-8/e is based on an entire ly new concept in minicomputer architectu re,
completely flexible , completely expandable .. Everything , including the CPU , just plugs
into the OMNIBUSTM . You buy only what you need, expand later if you want. And you can
start at less than $5000 for the basic 4K mach ine.

As we blew the dust off the interconnection file,
we realized - disturbingly so - that almost two
and one-half years have elapsed since the dramatic decisions on interconnection were announced. In seeking a good lead for a Clinic on
th at subject, the gestation period of elephants
came to mind. Regrettably, we found the period to
be 21 months, a period long past in the interconnection question. We can't resist pointing out,
however, that it was 21 months from the Carterfone decision in June of 1968, until the last Bell
jurisdiction, Michigan adopted the foreign
attachm ent language in its tariffs in March of
1970. The only other elephant statistic noted was
simply too depressing to relate to interconnection:
th eir average life expectancy is 60 years.
Excepting our history of the Carterfone case
( MODERN DATA, December 1968) and a report on
the DAA ( MODERN DATA, April 1969 ), we h ave
refrain ed from commenting on interconnection.
This has been because of its complexity
and its leverage. By leverage we mean that
even a slight swing in one direction on interconnection policy could have disastrous effects on
network reliability, while a swing in the opposite
direction could materially retard the contribution
of data communications to our socio-economic system. Where such swings are compounded by
being based on complex technical and economic
factors , decisions should be made slowly. And the
emotional overlay to interconnection requires compulsively careful analysis before such decision
making.
Notwithstanding a reluctance to add to the
sound -and fury, two recent events hav.e moved us
to leave the safety of "no opinion" and present our
own bias on the question. The first event was our
receipt of a paper entitled "Data Access or Data
Restriction" by Charles Johnson, President of Gen36
eral DataComm Industries. Mr. Johnson is qualifi ed as an expert witness by virtue of his role as an
independent supplier of data communications
products and by his prior experience in telephone
system engineering, both within and outside of the
Bell System. The paper is an extremely articulate
and forc eful development of Johnson's position
th at the Bell System tariff provisions on interconnection are "data restriction, not data access."
In particular, Johnson deals with the economics of
competition, which we will discuss below. The
force of his economic analysis, however, didn't
really hit home until the second event. In a recent
consulting assignment for a time-sharing service
supplier, we studied the use of independently supplied 103 equivalent modems. The most desirable
offering we found was a package of eight modems
in a small cabinet, which, on a three-year leasepurchase basis, priced out at $1l.41 per month per
line. This would have reduced the client's operating expense, even as compared with the Bell
113B (anticipated at $12-14 per month with first
quarter '71 availability). However, with the independently supplied modems, we had to plan on
tlle type CBT automatic DAA at $4.25 per month,
res ulting in: ( 1 ) no cost saving to the client, and
(2) a substantial amount of space tied up just in
DAAs.
This offends our sense of what is right. Let us
now turn to the Johnson paper wherein he develops this point, and we quote :
II. POTENTIAL EXISTS FOR UNFAIR
COMPETITION PRACTICES
Effective Bell System tariffs contain mandatory requirements that interconnection be via a Bell System-provided
dataset or, in those cases where a customer-provided dataset is to be used, via a Bell System-provided Data Access
Arrangement. No DAA is required by the tariff when a Bell
dataset is used . Therefore, within Bell System service
areas, they presently participate in each data service to the
extent of either a dataset or a DAA, and in every· case, in
the provision of the telephone line itself. The telephone line
and DAA devices can only be provided by the Bell System,
a situation characterized by an absence of competition. On
the other hand, the Bell System is presently allowed to
compete with independent dataset manufadurers concerning the datasets themselves.
MODERN DATA/December 1970
Cost I Rate Consideration
Since they must compete for this business, it is interesting to
co mpore the development of rates for a dataset in con trast to that for a Data Access Arrangement.

The interconn ection question is still under review by the FCC and its Common Carrier Bureau .
It will be recalled that the Commission simply
allowed th e tariff revisions to go into effect (January 1, 1969 ), neith er approving nor disapprovin g
of th em . Th e subsequent almos t two-year period
has been expend ed in:
• A series of informal conferences on tariff language and provisions be tween interested parties
uncler th e aegis of the Common Carrier Bureau .
When it is noted that the F58118 DAA is a minimum featur e unit, which does not contain remote test facilities or a
telephone set and, compared to a dataset, has a longer
life (less suscepti b ility to obsolescence) and lower installation and maintenance costs, it is seen that the proposed $4 rate is improperly based , exorb ita nt, and has the
effect of influencing data users to use Bell datasets instead
of those available from independen t manufacturers. If the
automqtic DAA rate is computed on a basis consistent with
that for the datasets, its monthly rate would be around
$1 .50, which is still excessive for a device to provide network protection. Th is is further compounded by the fact
that the installation charges for the DAAs are in many
cases the same as, or exceed, those for the much more
complex datasets.
• A stu d y of techn ical issues conducted by a select committee un der th e di recti on of the National
Academy of Sciences, th e committee membership
comprisin g professionals from common carriers,
suppliers of time-sharing service, equ ipment manufac turers, consultants, and engineers from universi ty research and laboratory activities.
• A study of the NAS report and the general subject of interconnecti on , cond ucted by D ittbern er
Associates and auth orized by the Commission .
• Filing of comments on th e NAS report by interested parties, completed by September 1, 1970.
O f mos t sign ificance were th e principal fin dings
and recomm endations of th e NAS report . We
quote from the report's letter of transmittal:
The Board hereby commends to you these principal technical findings of the study:
1. Uncontrolled interconnection to the common carrier
network as it now exists would be harmful;
' This charg e runs a s high as $6.75 per month in some sta tes, repr es enting an annual rate to selling pri ce percentag e of 253 %; the F57951
Manual DAA pe rcentages range from 108 % to 300% .
The fact is that the independent dataset supplier must concern himself with not onl y th e price
for his dataset, but th e DAA rate as well . Presum ably he can build his sets to m eet Bell offerings in
th e marketplace. However, h e must also justify to
his customers a furth er monthly cost for the DAA
(an exercise not required of Bell ) which is not
sub ject to competitive pressure. Fin ally, it appears
that Bell is usin g a different pricing strategy
on its non-competiti ve offering which , b ased on
Johnson's data, is anticompetitive and unfair to
independent suppliers. vVe certainly stand for
motherhood and network protection . W e find
abomin able, however, a high markup on th e requirem ent for en try of an indep endent supplier
to a market where no natural monopoly can be
remotely justified.
MODERN DATA/ De cembe r 1970
2. The re qu irements of the tariff criteria limiting characte ristics of interconnected lines are technically based and
in accord with the operational limits of the common carrier
network as it now exists;
3. The nature of potential harm, criteria for protection
against such harm, and the performance of various components of the telephone system can be specified explicitly
e nough to be understood and acted upon properly by
people with normal technical competencies.
Having found that harm of various kinds can occur and
that technical limitations on interconnection are therefore
necessary, the Panel studied protective measures. On the
technical basis of the third set of findings, the study concluded that the following two approaches- used either
alon e or in parallel in such proportions as non-technical
factors might determine-can supply the required degrees
of protection for the network, including network control
signaling :
1. Protective arrangements as required by the tariffs;

2. A properly authorized progra!l1 of standardization and
properly enforced certification of equipment, installation,
and maintenance.
Analysis of potential harm and protection capabilities revealed no technical reasons why innovation would be significantly restricted by either of the two approaches alone
or in combination . The choice clearly impinges on economic
and social problems and on questions of industrial structure
which are beyond the purview of the study.
Among the Dittberner findings, the significant were as
follows .
• Equipment with network protective capabilities is required to provide an acceptable level of protection. However, network protective " devices," per se, are not required.
• Common carri ers should not have an exclusive right
provide equipme nt with network protective capabilities
to the end-user.
10
• Although the NAS program of standardization and
certification of equipment, installation, and maintenance is
technically sound, its implementation feasibility is limited
by such non-technical factors as manpower and funding
availability.
They recommend that interconn ection should be
permitted without common carrier access
arrangements, provided that foreign attachments
meet network protection standards and are installed and maintained by an FCC-certified instalJa tion j main tenance con tractor.
As of this writing - ovember 1970 - th e
Commission and staff are presum ably mulling all
of the information submitted. W e look forward to
some policy jaction position in the near future. It is
apparent to us that some improvement is required
in favor of a more liberal interconnection policy.
Two and one-half years of little progress is a defacto postponement of th e importance of the
FCC's original decision. This is attested to by the
fact that as of July 1970, AT&T reported 1,658
DAAs installed. This amounts to about 1% of
switched network data sets - a far cry from th e
much heralded new era envisioned in 1968.
A NEW PROPOSAL
Our own view is that there must be network protection, in terms of power-volt age-frequency inputs, and in terms of reliability of network control
signalling. We do not believe these functions
should b e provided under a supplier's self-certification system because there is too great a potential
for damage to a system which it behooves us all to
40
see operating near-perfectly. On the other hand,
neither do we favor the common carriers' exploiting the need for network protection. It does
seem to us, however, that the interests of all could
be served by the following arrangement.
We propose that th e common carriers in concert
with EIA undertake design of standard modules
for network protection and network signaling in
digital communication applications. These modules
would be designed to connect to exchange circuits on one side, and to foreign attachment circuitryon the other. The attachment interface should
be such as to place all functional load on th e
attachment, leaving module circuitry only for network protection and network control supervision.
This would preclude th e costs of redundancy.
The modules would be designed to plug into a
standard receptacle on th e foreign attachment.
This would eliminate the need for extra space in
installing DAAs . This would also permit a common carrier serviceman to insert quickly his own
modules if he suspects problems in the access
arrangement. Alternatively, an appropriate tes t set
could be plugged into this receptacle for divisionof-responsibility tes ting.
These modules should be manufactured by historical suppliers approved by the common carriers,
such as vVestern Electric or Automatic Electric.
They should then be sold openly in the market, at
prices based on return on investment to manufacture.
We believe this proposal would meet all needs,
and also aid developm ent of data communications
in general. Manufacture by a carrier-controlled entity ass ures the quality and reliability required for
network protection . Elimination of redundancies
and outright sales based on pricing on return on
inves tm ent should remove th e common carriers'
present advantage in being able to supply data
sets without access arrangemen ts. As a refinement
on this, perhaps th e same modules could be required in common carrier datasets. Outright sale
would also resolve th e qu es tion of rate variances
between intra-state tariffs. Regulation of sale price
would be substantially less complex to implement
and administer than would be the various certification programs being discussed. Production by
one or two manufacturers should yield economies
of scale not available should each independent
supplier manufacture for his own needs. Finally,
standard plug-in modules would enable rapid solution of division-of-maintenance problems .
W e believe this approach would take no longer
to implement than presently considered approaches
of independent certification. Yet we believe it
would b e eminently more practical to administer,
and more clearly of greater import to industry
growth.

SOURCE DATA AUTOMATION
POINT -OF-SALE DATA COLLECTION SYSTEMS
Point-of-Sale ( POS ) D ata Collection relates to
recording all information needed to transact a sale
at tim e of purchase, i. e., item identification, price,
customer identification, etc. Th e two basic POS
acti vi ties are ( 1) writing-up or recording the sale
(2) checkin g custom ers' credit for a non-cash sale.
Since customers are awaiting th eir purch ase,
these activities must be perform ed quickly and accurately. In addition , with the ad vent of th e computer, POS information must also be placed onto a
computer-readable medium.
Th e Point-of-Sale data capture problem represents an ideal application for Source D ata Automation techniques since data recording can be automated at th e initial point of data generation. After
many years of stagnation, th e retail merchandisin g
fi eld is being bombarded by manufacturers, resulting in a new generati on of Point-of-Sale systems.
PRESENT POINT-Of-SALE SYSTEMS
Presently, most POS automation is implemented
by utilizing several different techniques, each for a
different POS activity. Sales recording is accomplished at th e cash register for a cash sale and by
hand for a credit sale. Numerous cash registers exist which simultaneously record data on paper
tape or print .data in OCR-readable font on journal
tapes . Furthermore, department stores are experim enting with automating credit sales by using
OCR-readable credit cards for customers' identification and using handprint OCR machines for
reading sales data. Checking on a customer's
credit involves th e use of credit card readers and
Mr . Feide l-man ;s a regu la r co ntri butor t o Source Dat a A uto mation .
42
push-button telephon es in some cases, an d voice
conversation in most. Finally, prepunched tags attached to th e merchandise and rcmoved at the
time of sale are used for determinin g th e store inventory. These tags, however, have th e disadvantage of not being alterable when th e item
price is changed.
Th e implementation of th ese equipm ents has
not resolved th e major POS probl ems of ( 1) data
entry errors caused by th e salesperson , ( 2 ) excessive tim e spent on credit verification , (3 ) excessive tim e spent on recording th e sale, ( 4 ) use
of num erou s different equipm ents from different
manufac turers , ( 5 ) duplication of data recording
and, ( 6 ) tim e delay ( in days ) between sal e
recordin g and customer billing.
NEW POINT-Of-SALE SYSTEMS
Th e integration of all POS functions into on e system and th e elimin ation of th e above problems are
the basic objectives of th e new Point-of-Sale data
collection equipments. These equipments are essentially self-contain ed electroni c calculators, most
of which can also be used as computer terminals .
The POS data collection device performs all necessary calculations on the entered data, i.e., tax, discounts, and sum . Data can be entered via th e keyboard or directly from th e merchandise tags. The
latter technique eliminates th e error-prone manual
input problem. Also, the equipm ent checks custom er credit on -lin e, places data in th e customers'
account, and records information for inventory
con trol. Th e proper entry sequence is indicated to
the salesperson b y a sequence of keyboard lights.
A display permits visual verification. The resultant
data is recorded in n1achine language onto a computer-readable medium.

( :\IDTS ) are rcpre!:ientative of the SDA approach
toward!:i a centralized computer !:iystem with remote terminals. The system design modularity permits the terminals to be employed off-line, with
data being recorded onto magnetic tape, as well as
on-line. Such self-contained terminals are a boon
to the smaller retail er who can't afford a larger
computer system , but can easily use a terminal as
an input to a remotely-located service bureau.
Another innovative system aimed at capturing
data with as little manual en try as possible uses a
special keyboard designed hy Information Technology, Inc. for the fast food industry. Instead of
entering prices, the salesperson enters th e name
and quantity of items sold ( 2 hamburgers, 3 coffees, etc. ) . The POS terminal , using stored p rice
data, th en performs al l necessary calculations . This
techniqu e could be extended to a department
store by previously storing the price for each item
and on ly entering th e item code into th e system
(preferably by an optical reader ), th ereby eliminating errors caused by price changes.
Prices for th ese sys tems presently range from
$3,000 to $5,000 for a single POS data collection
device, and $25,000 to $1 million for an en tire system. \tVith present tren ds in LSI technology, these
prices should be substan ti all y reduced by 1975.
In summary, then , Point-Of-Sale data collection
is comin g ou t of its infancy with th e adven t of
modularized integrated systems. Such systems will
permit both th e small an d large retailer to share in
th e use of this product from both economic and
operation al viewpoin ts.

A young programmer of our acquaintance had

THE SYSTEMS SCENE
SOFTWARE FOR SCHOOLS
Performance contracting refers to the letting of
contracts to private education companies to conduct specified courses in the public schools. In
most cases, compensation is made according to
actual results achieved by the students.
Emphasis is on a systems approach to education. Contractors, being profit-oriented, are necessarily dedicated to the development of new and
effective methods of teaching. The companies are
much more inclined than local schools to implement such things as teacher incentives, c.A. I. ,
programmed learning systems, and control group
testing of new ideas.
Is this good? It must be. Teachers' unions are
livid. The National Education Association has
attacked the concept in Congress and threatened
to take the issue to court. The American Federation of Teachers says th e idea is dehumanizing.
The United Federation of Teachers has sought an
injunction against performance contracting and
called the program a new Nixon plot. The New
Y01'k Times, in an editorial, said that such performance-oriented teaching was "percentomania."
Why are all these nice people so upset? Performance contracting has a number of characteristics that are particularly disturbing to some of
the groups mentioned. It is new, not very expensive, and it just might work. In addition, it implies that educators ought to be judged on the effectiveness of th eir work.
Unorthodox methods applied by a few of the
contractors have aroused considerable ire. There
have been incidents of children receiving candy or
trading stamps or extra free time as rewards for
doing well. What some unprincipled people won't
stoop to when teaching children to read!
Title I of the Elementary and Secondary Education Act of 1965 provides $1.5 billion in fiscal 1971
for extra education for the disadvantaged. The Administration is concern ed that little of this money
is being used effectively. The OEO and Office of
Education have started experim ents in performance contracting to attempt to change this situation. The first project was started in Texarkana,
Ark. last winter with a contract awarded to Dorsett Education al Systems. All current experiments
are aimed at groups of children with substantial
reading deficiencies. That statement is not enough:
Mr. DeMarco is a regular contributor to The Systems Scene
46
their present capabilities range from poor down to
heartbreaking. In many of the.se cases, the present
educational system has failed abjectly.
This is not an indictment of the teachers involved. Their task has too often been complicated
by children who were hungry or terrorized or
products of an emotionally disturbing home life. A
new approach is called for and performance contracting at least is new. Under the circumstances,
the opposition that has been mounted against even
testing this new idea appears unco~scionable .
Results of the Texarkana project were, on the
whole, extremely rewarding. Average reading levels of th e most successful group of students were
increased by 2.2 grade levels after 60 hours of special instruction. Later results were clouded by
charges that the curriculum had been too much
oriented toward the tests. These charges have
pointed out that more sophisticated accountability
standards must be developed to make performance contracting effective. All things considered,
the principals, teachers, and staff of the local
school board were highly enthused and now wish
to "turnkey" the system this fall. (Most performance contracting involves only one year of actual
implementation by the company, followed by
turnover of the systems to the local schools. )
Contracts have been let by 18 school districts in
16 states as part of the OEO program. Six companies are participating: Alpha Learning Systems,
Learning Foundations, Plan Education Centers,
Singer Graflex, W estinghouse Learning and Quality Educational Development. Education Turnkey
Systems provides management support services to
the whole project.
I talked to Charles Blashke of Education Turnkey Systems. His com pany is also building a data
base of performance contracting companies. So
far, some one hundred companies are actively soliciting contracts or have expressed the intention
of doing so. If this year's experiments continue to
be successful, ETS will provide a selection service
to help school boards contact contractors to solve
their particular problems.
Many of th e companies are made up of a blend
of education and ex-computer systems people. It is
this influx of systems people and companies into
th e staid area of education which is particularly
excitin g. RCA has already moved into the field.
Some of th e other strong systems houses like IBM,
Informatics, or PMI could be enticed to follow.
H ell knows no fury like a systems fim1 in search
of more profitability. If that kind of energy and
excellence can be channeled towards educating
the disadvantaged we all stand to win.

MIS FOLKLORE-AN OPINION
MIS is a folk myth . It fits all the requirements. It
is legend , und efinabl e, exciting, vague, perpetually
innovative, and revolutionary. And yet, real in
some (no one can know what ) respects. It can
mean anything anyon e wants it to mean . It is the
greatest idea invented since th e computer as a
"brain" in the early days of computer folklore. And
most of all, it is amazing that businessmen, those
pragmatic paragons of cost consciousness, are
spending millions of dollars trying to capture its
mystique.
DEFINITIONITIS
There is currentl y a wave of activity in defining
what is meant by MIS. The effect has largely been
the organizing of confusion. Most of th e problems
result from using buzz words like MIS instead of
plain English.
Consider how much information you obtain
from hearing laymen say that they "have a computer at th eir place." The professional's immediate
reaction is confusion and doubt. W e know only
that it may be a maxi, midi , mini, mechanical,
electrical, or even a complex th ermostat-controlled
device.
So what is MIS ? Vie don't know. But we doubt
you have on e because, by folk definition , a real
MIS is always something at least one step beyond
what is currently available. Seriously though, even
if we can't defiN e what an MIS is , we can relate it
to th e more generally understood concept of a
common data base system.
COMMON DATA BASE SYSTEMS
A common data base system is one in which data
from any fil e is referred to related data in all
oth er files. Along with this structured (rather,
Mr . Falor ;s a regular contributor to. Software Forum.
48
mu ltistructured hierarchal ) data base itself, with
its links, chains , rings, and what-not, com es a
couple of other things.
Th e first is a large mass of data - in fact , all
you ha ve.
Th e second is telecommnnicati ons faciliti es: the
black boxes on executives' desks, or at least, on
customer service clerks ' desks ( on e of th e most
appropriate places for th em ) .
A fin al item th at goes with th e monster data
base is a management system or software "keeper"
for th e monster. This is so th e ordinary programmer won 't ever have to come face to face with th e
monster. Th e programmer tells th e data base management sys tem wh at data he wants from it, and
the keeper has th e joh of going in and getting it
from th e monster.
A data b ase management system usually accom modates existing Cobol , Bal, etc. pl;ograms with
simplified data handling. It also permits changes
in th e data base structure without affecting th e
application programs. The data base management
system is what MIS really means to many people
that have lately b een exposed to "what's happening. '"
vVe persolJall y believe that the move towards
the complex common data base management system is a good direction to go, and th at it will be an
interesting place to get to, someday. In a few cases
such sys tems are here today. Too often, though,
the con cept is misapplied . W e feel that for most
. busin esses dealin g with more or less standard applications ( not counting model building ), it usually isn't economically or otherwise feasible to "go
all th e way" with present technology. Some of th e
innovations in mass, associative, and cheap highspeed bulk memory devices now in th e laboratory
must be brought to ,th e production line before th e
monster's upkeep can b e controlled , maintained ,
and made really practical for 99% of th e business
world .
In th e meantime, th e core of truly professional
business EDF- work lies in effectively utilizing
proven and practical resources to generate,
acquire, and upgrade essential systems and efficiently service user departments . And in keeping
aware of new data base management techniques
as they economically prove themselves.

We're winning by introducing three
new Nova-line 16-bit mini computers that go
faster and cost less than the competition.
We're winning by being smart.
By looking ahead at what mini computers are going to be used for.
By designing new computers to take
advantage of new technologies.
By staying one step ahead of the
competition.
We've been winning the
battles consistently.
.
In just 21f2 short years we've
mtroduced a complete line of mini
computers, software and peripher- ,
als, and we've grown from a total
newcomer to one of the big three.
Our latest victory can best
be described by describing our
three new machines:
SUPERNOVA SC:
The first mini computer with a highspeed all monolithic memory, making it the
fastest mini computer in the world.
NOVA 1200:
The first mini computer to take advantage of large -and medium-scale integration
making it very fast (1200 nanosecond cycle '
time) , most reliable, and considerably less
expensive than any other mini computer at its
performance level.
NOVA 800:
A new machine that offers even more
speed and performance than the Nova 1200
for the guy who needs it. At a price he can
afford.
The first mini computer
with all monolithic 'memory:
SUPERNOVA SC.
There's only one real reason to build a
machine around a monolithic memory: speed.
Not just cycle-time speed.
Real speed, that can only be measured
in terms of instruction execution.
The Supernova SC can execute arithmetic and logical instructions in 300
nanoseconds.
50
In a single memory cycle.
That's because we built the Supernova
SC processor around its monolithic memory.
It overlaps the instruction execution
cycle with the fetch of the next instruction.
Which takes advantage of the real
speed break available with a monolithic
memory.
As we said, we used a monolithic memory in order to take advantage of it.
Not just so we could say we had it.
Price: $11,900 *
The first mini computer
to use LSI' and MSI to gain
performance and economy:
NOVA 1200.
Other machines use large-scale
integration.
No machine has used it as effectively
as the Nova 1200.
We've combined LSI with a high
degree of medium-scale integration.
Not just so we could say we did.
But so we could drastically lower the
parts ~ount, increase reliability, lower cost,
and stIll make the Nova 1200 2% to 3 times
MODERN DATA/ December 1970
faster than its predecessor, the Nova.
So we could offer a mini computer that
ranks, in terms of performance, at the upper
end of the multi-accumulator 16-bit machines,
yet sells for about the same as most singleaccumulator 12-bit machines. Price: $5,450. *
The faster, more
powerful Nova:
NOVA 800.
For the guy who wants more speed but
doesn't want to spend much more dough, we've
got the Nova 800.
Faster, more powerful than the 1200,
Nova 800 has a fully parallel central processor
and a basic cycle time of 800 nanoseconds.
But what makes it extra special is its
extremely flexible 10 structure that allows it
to handle a heavy load of 10 traffic of varying
types and speeds.
Price: $6,950. *
We're more than
machines.
O.K.
So now you know something about
each of our new mini computers in particular.
N ow we want to tell you something
about all of our computers in general.
They're compatible.
The first Nova we ever built uses the
same software, the same 10 interfaces, fits in
the same amount of space, uses the same
peripherals as our new Supernova SC.
They offer systems manufacturers a
range of machines and performance options
that they can plug into a system without any
modifications, all backed by as gener ous an array of discount schedules as you'll find anywhere.
We mentioned software.
We've developed a complete
line of it.
Big computer software,
designed, not scaled down, for mini
computers.
Like ALGOL 60,
FORTRAN IV, Time Shar ing
BASIC, and Disc Operating System.
The same goes for our peripherals:
disc systems, industry-compatible mag tape
units, paper tape equipment, card readers,
line printers, real-time clocks, A I D, DI A,
communications equipment.
As you can see from all of the above,
we are and have been winning the mini
computer battles.
Simply because we've consistently
come up with the mini computers, and all that
goes with them, that perform better and cost
less than ever before.
To the victor go the spoils.

UP THE SYSTEM DOWN-TIME
WHERE DID ALL
THE FLOWERS GO?
Formalization Of Modern Psychological Motivation Theory . . .
The trouble with present thinking about motivation is that there are too many experts with unchallenged credentials telling each other what to
think. It is thoughtless of them.
The collected experts have become a virtual industry dealing with the subject of motivation and,
as is the case in other industries, no fresh thoughts
on the subject should be expected from them.
They talk with each other too much.
Those of you who have not been completely
brainwashed in these currently accepted misconceptions about motivation will be the first to
realize that motivation is a natural, inherent characteristic of life and can be created neither by
man nor by manager. All forms of animals (man
included) naturally seek food , shelter, and pleasurable stimulation on their own accord without
being otherwise motivated to do so. Although this
may seem to be a wildly radical concept to some,
our job is not to motivate; but rather to minimize
those things we do to de-motivate our employees.
Once one appreciates this fundamental truth, it
is easy to see that the leading factors contributing
to de-motivation are those thin gs which we do to
motivate. A case could be made that th ere is a
whole youthful generation that has been so motivated by parents, teachers, and TV commercials
that it has lost faith in just about everything; most
particularly parents, teachers, and TV commercials.
Several large corporations have already seen the
light and have stopped playing games with rubber
tree plants, parking spaces, drapes, carpets, and
52
the secretary to decorate them. D espite the dire
predictions of the recognized motivational experts,
this action has had phenomenally positive effects .
It is just one more example that people are wonderfully motivated, if we can only stop motivating
them long enough to find that out.
SELECTION CHARACTERISTICS
The systems organization searches for resourceful ,
innovative people with perception, drive, and all
th at other good stuff. The systems organization
gets and keeps such people becausc it offers a
higher monetary consideration and because dealing with computer systems is an I.Q. test that drives
those who lack the aptitude out of their gourds.
Those who stay in systems development for a
number of years are not nesters who like the routine of a rut. These people seek challenge and are
happiest when they are "participating in the development of new things." They are poor at standing in line and tend to get bored doing things that
they have learned all about. Thus they pJay bridge
and chess but seldom bingo. If you put one in
charge of an operating department, he'll generally
get it going until he learns th e job, then he'll get
bored and let things get screwed up again.
When a systems man is challenged he will plug
away, resenting only those things that seem to
needlessly interfere with his project. It is only during the periods when he is unchallenged that he
notices that he is over-worked and under-p aid,
and that his boss is dull and unimaginative. It is at
MODERN DATA/ Decembe r 1970
such times that the systems man is motivated to
put out resumes systematically.
We try to select people who are resourceful and
who constantly demand new challenge. Those
who prefer routine eventually find th eir way in to
other operations. It should th erefore he obvious
that th e most effective methou of de-motivating
systems people is to do th e following:
• Leaue them unchallenged or idle, eue n briefly;
• Permit interference with th eir projects;
• Re-assign them. to anothe r project before they
lwue achieued their objecti1)es on the current one;
• Assign them (o r promote them) to routine jobs;
• Con them.
It is with great iron y that we managers find ourselves doing th ese things, not only because it costs
us good men; but also because these are the very
things that frustrate the success of projects which
we are hired to manage. It is even more ironic that
we do these things systematically. ( Do not stop to
think, go directly to the next topic . . . )
PRO JECT DEVELOPMENT AMONG THE APES
Things which are mass produced call for a relatively static production organization in which specialization can develop out of practice ( monkey
see, monkey do ). This seems to be substantiated
by th e experience of H enry Ford and others.
Things which are not mass produced, but which
are one-of-a-kind, call for a different kind of an
organi za tion . Since a detailed blueprin t and specifica tions cannot be made available in advance, a
grea t deal of judgemen t and competence is expected of the leader. Development of unique projects requ ires what has come to be known as project organization . (If yo ur projects are not unique,
go buy some software !)
The pure project organization is the oldes t form
of organization an d sprang from th e need for two
or more men to gang-up on a bear. Someth ing of
the essence of true project organization was lost
when th ese men began to routinely gang-up on
bears, and began to specialize between bear-find ing analysts and bod-to-bod contact men, or
"closers" as th ey were th en called. The first primitive functional organization was p ossible only b ecause th e objective (a bear ) was understood by
everyone and was a relatively standard entity.
( Mos t bears look and act about the same. )
MODERN DATA / December 1970
One thing which is common to both forms of
primitive organization ( project or functional) is
that the leader decided how the rewards ( bear
components) would be split up . Otherwise, h e
would find some other gang to leau because if you
don't distribute the reward, you aren't the leader.
Analysis of primitive cave drawings on several
continents has failed to yield a single exception to
this policy.
Project organization is inherently more difficult
hecause th e project leader must continue to see
that th e objectives are defined and communicated
within the project group. This explains why the
most strikingly successful projects ( inventions )
are usuall y done by only one or two individuals.
The communication of objectives on a one-man
project effort is usually pretty good and such projects are normall y under control.
It is only in modern tim es that we have become
sophisticated enough to remove the function of reward distribution from project leaders and have
placed the majority of the rewards well above the
level of project control. In fact, we have become
so expert at th e science of management that one
wonders why we have such troubl e getting projects done.
It would be atavistic and reactionary to ask a
cave man abou t project management; what could
he know about organization and motivation?
WHY PLANTS GET POTTED
An industrial biologist acquaintance of mine is
presently engaged in a project of some m erit. His
project has all the ingredients of success in that
( 1 ) he controls and communicates perfectly wi th
his group ( it is a one-man p roject ), (2) he requ ires cooperation and support from no outsiders
and, ( 3 ) he expects to share in the rewards of his
work.
He is developing a hybrid carrot crossed w ith a
stick wh ich he hopes can be used as an all-purpose
moti vational device. He is encouragin g the hybrid
to grow by h anging fancy drapes in th e greenhouse, carpeting the walkways, and using liberal
doses of manure. He was considering th e use of a
rubber tree plant, bu t feared that this migh t constitu te com petition and th erefore intimidate the
hybrid.
He req uested my ad vice, as a sys tems professional, but I coul d offer him none. After all, he was
following all the cOl1\[entional procedures. There is
one thing about his greenhouse th at I wonder
abou t . . . Where did all the flow ers go?

Jim Baker is an M.I.T. graduate
(math major and honor society

So when Ken wrote the user's
manual for CULPRIT he put himself entirely in the user's position.
Example: he devoted a major
effort to a self-teaching section
for junior level personnel ... but
at the same time included substantial material for the advanced
CULPR IT user.
Kenneth Falor
Prior to joining Cullinane Corporation, Jim spent 5 years in advanced software system development atI.B.M. Therefore, Jim was
the logical choice to develop the
IMS/ data language 1 interface
module ... which allowed CULPRIT to enhance the report generator capability of DL 1.
From this experience evolved
the obvious need for a powerful
report generator. One that would
be easy to use, yet so powerful
and fast it could be used as a
report utility as well as for on-demand reports. In other words .. .
CULPRIT.
Jim was also a major contributor
to the as version of CULPRIT.
Meet the people behind the most important
software package of 1970: new CULPRIT.
Before many months are out the ch ances a re
you ' ll be using CULPRIT. Wherever it ha s
been shown it has generated intense interest.
The list of sales is grolVing quite rapidly. And
it is the type of package literally everyone
needs.
So \Ve thought you'd like to meet a few of
the more important people behind it. Th ere are
others. Perhaps a dozen Cullinane staff members had some part in CULPRIT. But these are
the four who deserve the credit.
CU LPRIT brought us a few s urprises. Parti cularly in speed. While we des igned it for
flexibility and ease in use CULPRIT turned out
to be mu ch fas ter than our most opti mistic
es timates. Oth e rw is e it performs exact ly as
planned.
And w hat \Ve planned was an easy- to-use

How CULPRIT differs
Many repo rt ge nerators can produce only
one report from one pass of the data fi le. Othe rs
produce a Cobol program wh ich must be com-
piled, link edited and run before they produce
a report. Some even ha ve both problems.
That 's Model T designing!
CULPR IT is a parameter-driven program.
No compiling needed. The program is kept on
th e core image library like a utility and produces a report as directed by the parameter
coding. Highly efficient , it produces many reports (up to 99) with a single pass and can ex tract from multiple inpu t files.
CULPRIT req'uires from 1 /10 to 1140 the
normal coding time. This means that the most
jun ior-level progra mm er can request and ge t
a s impl e one-tim e repor t in minutes. Or many
complex reports in o ne pass ... with just a few
haUl'S of coding . Not weeks. Hours! But fast

burst errors detected at th e receiver can be corrected without an y retransmission . This error process has been used in military and sec ure systems,
hut compl exity and expens e h as kept the process
from bein g applied in commercial modems .
The transmitter of th e D atamax unit has a convolutional encoder that interl eaves parity bits with
th e binary data stream . Th eir encoder adds 50%
redundan cy, or 2400 bps, to th eir 4800 bps data
stream , and interlaces th em. Th e res ulting 7200
bps are transmitted to th e receiver.
The receiving mod em has a threshold decoder
that compares a number of equations that use th e
incoming data bits as variables. One bit at a tim e
is considered for correction before being passed on
to th e system , and if th e data has b een corrupted
by random bits or bursts cif noise, the error bit is
changed (corrected ) . Th e res ultin g data stream of
4800 bps h as a very hi gh probability of b ein g free
of errors.
MULTIPLEXERS
:vIultiplexing, which is not a new art, can save
money b ecaus e it is a technique that provides
more effici ent us e of circuit bandwidth and more
efficient use of th e time available for transmission .
Multiplexing permits many terminals to share one
elephone line.
The technique is b est employed wh en a number
f remote terminals, located reasonably close to
each other, require long dedicated ( private)
phone lin es all th e way back to one computer site.
One multiplexer at each end of one long dedicated
phone lin e allows that phone lin e to b e shared by
the man y terminals, and thus th e high cost of lin es
to each and every terminal can be eliminated . Th e
decision to multiplex or not depends on th e comparison of mu ltipl exing equipm ent cost versus th e
cost of th e phone lin es .
There are two ways to multiplex information
onto one telephone line. The channel bandwidth
can be divided into a number of narrower frequency bands that are isolated from each other; or
th e real time that is available can b e divided into a
number of smaller tim e segments. The first
method is called frequ ency-division multiplexing
( FDM ) and the second method is called tim e-division multiplexing ( TDM). Both systems are digital (EIA or ®S232) end-to-end and interface modems at the remote terminal end, while directly
going into th e communication subsystem at th e
computer end. In all cases, the circuits appear independent to the user.
An FDM system must divide th e existing 4KHz
channel (voice grade line) into smaller bands that
66
can handle th e low-speed data rates. This is done
wi th band-p ass filt ers which h ave characteristics
that cause a loss of usable bandwith b etween
chann els. Once the filter characteristics, the usable
chann el bandwidth , and the necessary narrowband requirements are defin ed, th e number of deri ved narrow bands is fixed . If more narrowband
channels are required, anoth er FDM system must
be in stall ed.
TDM provides more economical us e of a voice
grade telephone line b y translatin g a number of
slow speed inputs into a high-speed output. Each
input has its own tim e slot in the high-speed
stream - like box cars on a train - and at the
other end of the line th e conten ts of the box cars
are placed into th eir respective output locations.
Th e system might interl eave chann el data by bit,
or by character; in most cases it is flexible enough
to handle two or three input data rates, various
code lengths from 6 to 11 bits /character, and one
or more stop-bits/ character.
A TDM sys tem h as greater capacity than FDM ,
utilizes bandwidth more effectively, and is readily
exp andable. For example, 16 terminals at 150 bps
can be multiplexed onto one voice grade lin e with
a 2400 bps modem. The system capacity can be
doubl ed b y going to 4800 bps instead.
However, FDM has advantages over TDM. It is
less expensive, if th e number of remote terminals
is less than 16, and can b e more economically implemented when th e terminals must be dropped
from a party lin e, with a small number of terminals
at each drop-off point. This is b ecause th e FDM
hardware is channel-oriented, while th e bulk of
TDM hardware is required at each site regardless
of wh eth er th at site has one or twenty terminals.
Comparing Multiplexers
All mu ltiplexers are used for the same purpose to redu ce the total network cost in a computer
communication system. The primary paints of
com parison are system capacity, speed intermix,
multiplex m ethod, operating modes, transparency,
and test and fallback facility.
Systems always expand, so th e ability to add
more channels is important. In TDM sys tems it
means the ability to us e higher speed output modems with no change in slow speed characteristics;
in FDM systems it means the addition of modular
circuitry for th e additional channels. Consideration must also be given to the development of
multipoint systems and the potential requirem ent
of multipoint expansion.
The terminal types and th e location of the terminals in th e network should initially be
approximated without regard to any particular
multiplexer. After the initial layou t, the multiplexer requirements should fall into place and proMODERN DATA/ December 1970
vide a basis for comparison. The terminals determine the present speed intermix; the quantity of
terminals and their clustering determine the operating mode (point-to-point, multipoint, or concen tration ); the cost (considering expansion) should
determine th e multiplexing method.
A transparent multiplexing system is one that
can be inserted between terminals and computers
without either piece of hardware knowing about
the insertion. This is a prime consideration when
the initial system allowed the terminals to dial a
long distance connection to the com puter and the
modems had to recognize the ringing line, indicate
the presence of carrier, and note th e operative
condition of the computer. A transparent multiplexer will pass th ese signals from end-to-end, and
hardware does not have to be altered.
If erratic performance due to system degradation is not tolerable, th en fallback and test facilities are an important point of comparison. Loop
back switches and speed shifting become helpful
system features.
FDM System Description
A typical FDM system can multiplex 15 full
duplex data channels, in increments of three, onto
a four-wire telephone line. This system may be
point-to-point, or multipoint. The line may have to
be conditioned depending on system capacity. At
the remote multiplexing location, the interface
plugs into 300 bps lO3-type modems to handle
data rates of no, 134.5, and 150 bps. At the computer site, no modems are necessary, and the multiplexer interface plugs into the communication
subsystem directly. The Ring Indicator, Carrier
Detector, and Data Terminal Ready leads of the
RS 232 interface are utilized at the remote end
because every rem ole terminal dials into the FDM
system. These Signals are passed on through the
system and appear at the communication subsystem interface as if the dataset were directly connected.
The terminal would dial a local number and be
connected through an acoustic coupler or modem
to the remote multiplexer location. Signals are
then translated in frequency to a higher system
frequency and sent to the demultiplexer at the
computer end. The demultiplexer will demodulate
the analog signals, convert them to digital data,
and pass the data on to the communications subsystem.

AS MODEMS BEGIN TO "DISAPPEAR"
election of modems for dial-up telephone
line application prior to 1969 was
simple - call the local telephone company.
The FCC Carterfone ruling opened the way
for independents to supply modems, giving
end users a choice of vendors. However, during most of 1969, non-Bell modems were offered only in free-standing configurations (i.e.,
enclosed in a separate cabinet with power supply, cable, and connectors).
S
Today end users can choose to have the
modem incorporated into the terminal (integral). The question is - should the end user
care whether his modem is integral or freestanding? Cost, reliability, operator convenience, vendor relationships, and system
packaging are key differences.
Modem cost has become an important factor in total system cost as less expensive terminals appear. Looking at 103-compatible
modems as an example, rental from Bell totals
$300 per year plus an initial installation
charge, with no purchase or lease with option to
purchase plan available. Integral 103-compatible modems can be purchased at an added
cost to the terminal for $300-350, an amoun t
equal to one year's Bell rental. PIices of freestanding 103 modems vary in the range of
$400 to $500.
Improvements in reliability are gained with
integral modems. The interconnection scheme
is simpler and is controlled by the terminal
manufacturer. No redundant power supplies
are required. Since an RS232 interface is not
required between terminal and modem, interface circuitry is less complex. Furthermore,
when maintenance is required, integral modems obviate the necessity of working through
a separate vendor's field service organization;
MTTR times are negligible in that "card
swapping" is employed to repair a malfunctioning modem .
Packaging the modem inside the terminal
also provides for less complicated operating
procedures. Operators have one less "box" to
be concerned about and fewer switches, etc.
to work. The value placed on floor space in a
given installation and the aesthetics of a
streamlined system package weigh in the favor
of integral modems as well.
Integral modems have recently been described as the "wave of the future"; reviewing
the factors outlined above makes it easy to understand why.

possible and will be used more frequently in future computer communications systems because of
the usefulness of batch terminals that operate in
the range of 1.2 to 4.8 kbps. A medium-speed system that can multiplex eight channels at 1200 bps
onto one line via a 9600 bps modem will be examined in more detail.
The high-speed side of the system interfaces the
phone line through a 9600 bps modem that uses
automatic and adaptive equalization, while the
medium-speed side of the system offers an RS 232
interface for direct digital connection to communication subsystems, and also to 1200, 1800, 2400,
and 4800 bps modems . Access to the mediumspeed modems can be from terminab ::>r remote
computers that are either on dedicated lines or on
dial access circuits.
The multiplexer is transparent to the terminals
so that existing facilities can be multiplexed without requiring any modifica tion to the hardware
and software of the previous arrangement. The
control signals on the RS 232 interface are passed
from end to end using the normal data channel
during time slots when the channel is not transmitting data.
Trouble in a communication system might take
on one of two characteristics: reduced perform ance due to line or component degradation, or inability to communicate due to circuit or component failure.
In TDM, it it is possible to limp along until the
degradation problem is solved by shifting to a
lower transmission rate. A switch on the multiplexer can shift the speed from 9600 to 7200 and
4800 bps, and there is a patch panel that selects
those circuits allowed to remain on-line during
speed shifted operation.
Line degradation in FDM usually shows up as
poor response in the edge (outside) channels of
the frequency band. The center channels can still
operate satisfactorily, and in case of priority, the
importan t channels can be moved to the inside,
while the edge channels are temporarily dropped.
Where a total failure occurs, one must know
quickly if the fault lies with the computer, the
multiplexer, the dataset, the circuit, or the terminal. A quick way to determine the location of
the failure is through loopback circuit capability
and systems diagnostics. Loopback circuits cut the
modem out of the circuit by turning around its
analog and digital interfaces, and cut the multiplexer out by turning the receive module around
to the transmit module.

Concentration
A concentrated circuit configuration is one in
which there are more terminals having access to
the computer than there are ports on the comp uter
to service them. The object behind concentration
is the conservation of telephone line costs, better
utilization of channel capacity, and reduction in
the number of computer entry ports. System efficiency and economics depend heavily on these
items.
In a concentrated circuit systcm , each terminal
operates in contention, or contends for system
access with th e other termin als that are liable to
b e using all the computer ports at the time that it
wishes to do so. If the system is multipoint (having more than two drops) the local terminal users
in one area must contend with th e users in the
other local areas as well as among themselves. At
the computer port it is also possible to run in a
contention mode.

Assume that two remote concentrators with
three ports apiece are connected to a multipoint
circuit that demultiplexes into three computer
ports. If the configuration has two remote users on
concentrator 1, an d one remote user on concentrator 2, th en all three computer ports would
be occupied. At th at point in time, the concentrator is acting as a multiplexer and is interleaving data from the three connected remote terminals.
In actuality th en, an ideal system for specific
applications can be deSigned by using devices that
are combinations of concentrators and multiplexers. As a result, a number of high priority, or
high traffic, termin als can h ave access at any time
through th eir private, reserved chann el, while the
low priority and minimal users may contend for
access to the computer.
THE FUTURE
There are many independent manufacturers of
modems and multiplexers. This desirable situation
provides competition , which results in low prices
and high reliability. Many of these companies are
small and/or new, and although they deserve
credit for their inventiveness and a chance to
prove their performance, th e us er must make sure
that a system designed around the hardware of a
small independent can be adequately supported
and serviced.
In the future, the user will become more involved in the selection of multiplexers and less involved in the selection of modems. Modems will
lose their identity. The modulating and demodulating functions will be built into the terminals,
allowing th em to connect to the telephone network through the phone company's direct access
arran gem en t.
The choice of multiplexers will become more
complicated because the network will require sophisticated, programmable multiplexing. In the total system, hardware multiplexing (as described in
this article) will still be used for low performance
terminal clusters in order to save telephone line
costs; computerized multiplexers will be used at
higher level network nodes for improving total
system efficiency.

AND IN THIS CORNER ... RCA
RCA's New Computers: So nte Initial Reactions
COMMUNICATIONS ASPECT
EDITOR'S NOTE: Th e follo wing comments refer to
the new family of RCA computers - the RCA 2, 3,
6 , and 7 . This family is meant to be competitive
with the existing 3rd g eneratio n market . .. the
IBM 360 130, 40, and 50 . . . and is software
compatible with IBM 3601370 source language .
BASIC FEATURES OF RCA/S FAMILY
RCA 2 - A small-to-medium scale realmemory computer with memory sizes ranging
from 65 to 262K bytes. A typical RCA 2 with
a 131,072 byte memory will rent for $15,400
and. may be purchased for $700,000.
RCA 3 - A small-to-medium scale virtualmemory computer with main memory ranging from 131 to 262K bytes, and a virtual
memory of up to 2M bytes . A typical system
with 131,072 bytes will rent at $18,900 and
sell for $880,000.
RCA 6 - A medium scale real-memory computer with memory ranging from 262K bytes
to 2.1M bytes. An RCA 6 with a 524,288 byte
memory will rent at $29,300 and sell for $1,380,000.
RCA 7 - A medium-to-large scale virtualmemory machine with a main memory of
from 262K bytes to 2.1M bytes. A typical system with 524,288 bytes of main memory will
rent at $36,300 and sell for $1,680,000.
RCA 8660 Front End Communications Processor - The FECP provides full communications support for the RCA family and can
interface with remote devices which use
IBM's binary synchronous communications
procedures. The standard configuration,
available with a 32 or 66K byte memory, includes data exchange control, time control,
and console typewriter.
80
I was most interested in the announcement of th e
Model 8660 Front End Communications Processor
(FECP). Unlike IBM , RCA seems to have made a
more definitive commitment to the communications area. Obviously, both the System 370
and the new RCA computer systems have been
specifically designed for the "remote computing,
integrated system, large data base needs of the
1970's." TIle details of th e 8660 front end systems
are still sketchy however, and it appears that this
model more closely satisfies the definition of a programmable front end. This approach is one that
we at Interdata have successfully used to provide
the required flexibility needed to meet the
advances in remote processing and data communications.
However, this is only a start. Obviously as the
requirement for data communications continues to
grow, more advanced facilities will be required.
Coupled with this is the need for improved front
end telecommunication software, and the support
of "non-standard terminals." The approach typically taken by IBM (and perhaps emulated by
RCA) is oriented towards the USe of large software modules which reside in the expensive main
frame core memory. The independent approach,
such as our own, which might be categorized as a
"plug-for-plug compatible" system, has been to
reduce significantly the telecommunication overhead in the main frame by transferring this workload to the lower cost front end system. With the
increased standardization of main frames and telecommunication networks the users will undoubtedly be more responsive to the lower cost approach.
\iVhile my principal comments have been directed toward one peripheral model of the over-all
RCA system, I think that the commlmications area
represents one of the more significant areas of the
future.

MODERN DATA/ December 1970
A MARKETING STRATEGY
RCA's announcement of th eir new series of computers follows th e lead set by IB\l in that the
most important characteristics for these computers
are marketing strategies rather than technological
developments.
The series is directed at the largest dollar segment of the computer market, namely the IB\I
System/360 \l odels 30 and 40.
By anticipating IByl strategy for replacement of
th ese computers with the .370 ~lodel 13.5 and 145,
RCA hopes to attract some 360 users in the process of upgrading; a small increase in the customers' share would be significant for RCA.
RCA has taken a calculated risk, in trying to
outfox IBM. This could be a lethal mistake, especially since it may have set patterns for the other
computer manufacturer announcements only to
have IB:\I change prices or specifications.
To encourage IBM users to switch, RCA is offering: • A low-cost service guaranteeing conversions from 360 to RCA; • A virtual memory
capability; • A communications front-end; • An
emulation capability;. Some new peripherals.
RCA will most likely gain a share of the market
from the IBM 360 Model 30 and 40 class, but will
no t be able to compete for the \1 0del 50 conversion against the IB\!( 370/155. In the process,
RCA must erode its own revenue base in th e
Spectra 70 series, and will find it difficult to keep
th e new software requirements maintained and
updated.

MEETS THE USER'S NEED
For th e first tim e, IBM's third generation customers have a viable option to convert to an IBM
competitor's computer with a predetermin ed and
guaranteed conversion cost! RCA now makes this
offer to IBM 360/ 30, 40, and 50 users - representing over 50% of IBM's System / 360 users. They
expect to extend the oIrer to other 360 us ers at a
later date.
MODERN DATA/ December 1970
This courageous attack at tile very heart of
IB\I's business, opens a whole new path for these
IB:\I users - bothered and bewildered by unbundling. Since RCA has also a bundling option,
the user has a good opportunity to identify and
project his total costs more precisely. RCA has
provided a pathway to remove the fear the averagc user has about the possibility of leaving "big
brother."
The result gives RCA the potential to capture
25% of IB~I's market by 1975. RCA's chief executive, Robert Sarnoff, has made the corporate com mitment. The head of the computer effort, Ed
Donegan, has the knowhow. It remains to he seen
if they can train enough qualified salesmen and
support staff to compete head-on with IB\I and
win a significant percentage of the time.
The customers they do win are likely to he satisfied, since the guaranteed conversion contract carries a daily penalty clause for overruns. RCA is
learning the IB\I view that customers will buy
convenience - in conversion, services, and finances - and not just promises of better systems
and faster technology.
Robert Sarnoff said, "The progress of the computer business in the 1970's will be determined
more by specific needs of the users than by further
radical changes in technology." This view was corroborated by many leading computer users in 15
industry, government, and professional areas at
th e recent ACM '70 conference in New York City.
This was the first com puter conference, and h opefull y not the last, held specifically for users to describe th eir needs to th e computer industry.
By taking a thorough systems approach to the
computer business, and by making a sound, long
term dollar commitment, RCA predicts th ey will
have a billion dollar computer business by th e late
1970's and b e number two in the industry. They'll
have to overtake Hon eywell Information Systems,
In c. ( th e result of th e merger with C.E.) and others. RCA has clea rl y recognized that th e only way
to reach that goal is to attack IBM right where it
hurts - by takin g th eir custom ers away. It can be
done, but it takes plenty - courage, mon ey,
knowhow, hard work, thousands of hungry salesmen, and training.

The PEC 6000 Series 75 ips transports use mechanical buffer arms
and 10-J~ inch reels , and are specifically designed for use in minicomputer systems. The design of
the mechanical buffer arms and the
elimination of vacu um system components ensures that there are no
velocity transients and no overshoot. The simplified design also
means program-restriction free operation at 75 ips. Th e synchronous
transports offer high data reliability in 7- and 9-track NRZI USASII
and IBM compatible fonnats. The
PEC 6600 Series offers the same
high performance for the 9-track
1600 cpi phase-encoded USASII
and IBM compatible formats. They
are available in read-after-write
and in write/read versions. The
transports also offer other features
such as program-restriction free

Here's how we can
raise efficiency, yet
lower costs.
What we do: We're an organization of
engineers and managers providing professional technical and management consulting services to users of data and
telecommunications equipment, or to
manufacturers of this equipment. Our experience encompasses all of applied data
and telecommunications. Typical areas
include:
Data transmission • voice services • network design • terminals • interconnection
• private microwave • international communications • teletypewriter systems
As a user, you would utilize our services to implement a system,
improve it, lower costs, or perhaps all three. Or request counseling,
feasibility studies, systems design or communications management services. If you're a supplier, our services help you achieve
more cost-effective product and business, planning. Counseling and
studies include market trends and needs, product concepts and technical design, regulatory matters, and the competitive environment.
How we do it: Because our client's people have to live with our
results, we work closely with them. We reject textbook answers if
an innovative approach is sound. We design computerized models
to analyze and weigh all possibilities. We document our findings
MODERN DATA/ December 1970
so the client can test them. And we help
our client's people follow through on our
recommendations. Soundness and logic
are consistent - whether we're recommending a new product, or configuring a
nationwide message switching network.
What we can do for you: We can help
you get more for your dollars, speed up
your program, avoid costly mistakes,
raise efficiency yet lower costs. How?
Because we apply our knowledge of equipment, services and trends acquired through
working for manufacturer clients; and because we do the same with knowledge of
the needs, practices and applications acquired from user clients, But most of all,
perhaps, operating independently of any
equipment supplier or communications
service affords us the privilege of being
completely objective in our approach to problem-solving. Which
means we serve only one master: you.
For more information ... Write or call us soon. We'll discuss your
interests in depth, or provide literature on our U.S. or European
services. Whether we can help you or not, there's one thing we'll
maintain our reputation for: an honest answer.
