APRIL 1971
We've made a great computer
a lot better.
Varian's new 620/L has a dramatic
price/performance ratiothatgives
more computer in less space at
lower cost. The 620/L is an
advanced design of the reliable,
field-proven (over 1300 installed
worldwide), systems-oriented 620/i
computer.
Priced at only $7700, the 620/L
has an 8K, 16-bit, high-performance memory that can be expanded
to 32K inexpensively. Each 4K
memory increment is$2300. What 's
more, if you don 't need 8K, you 'll
find the basic 4K, 16-bit 620/L very
attractive at $5400!
The 620/L is small , so small that
when fully expanded-a 32,768word system with all main frame
options and up to eight peripheral
controllers-fits into just 21 inches
of rack height.
The 620/L is 100% I/O-and software-compatible with the 620/i,
and new peripherals and software
have been added . All peripherals,
software, and appl ication packages
(developed for earlier 620 models) ,
as well as the 620/L itself, are offthe-shelf.
You know us. You know that when
we say we have something better,
we can prove it. Talk to the big company in small computers.

INFORMA nON INTERCHANGE BETWEEN DISSIMILAR COMPUTER SYSTEMS
How best to apply ASCII when inte1"changing data between dissimilar computer systems?
This article analyzes data interchange, first examining codes and then looking at the interchange mechanism. Three problems are discussed: the problem of transferring data files
from one system to another; the problem of converting a single system's files to ASCII; and
the problem of transferring a high-level language application program from one system to
another.

Statos 21 will print 300 pages of charts, graphs,
and text while the boss has his coffee.
(But he'll have to drink fast!)
This new printer/plotter, latest in a line
of electrostatic devices pioneered by
Varian , can deliver hundreds of pages
of computer-generated text and graphics while you take a 5-minute coffee
break. That's four times the speed, at
half the price, of most impact printers.
And it does it in a 2-foot square without
a wh isper.
Statos 21 page-a-second printing is
a full 8 112 x 11, 80 column by 88 lines
page. And its turn-around time in data
processing applications is phenomenal!
Just imagine: Core and tape dumps in
seconds. Top management summaries
generated in minutes, while bulk printing cont inues. Graphs printed simultaneously with alphanumeric characters ,
much faster than with separate printers
and plotters. Card-image records and
teletype-compatible listings handled
with ease.
A problem solvi ng computer periphera l-Statos 21 is plug-to-plug compat-
ible with IBM/360, Varian 620/f and
other computers both large and mini.
The fact is, nearly every data processing and management information system can benefit from Statos 21. So for

FULL COMPUTER POWER
FOR A FRACTION OF
THE COST.
A unique concept - the minicomputer as a component - has been
launched by Computer Automation.
Called the NAKED MINF", this
new computer delivers all the power
of a packaged machine . .. at a price
that breaks through the $2000
barrier.
The NAKED MINI is a fully operat ional 8-bit or 16-bit computer,
stripped of its power supply, console, and metal chassis . You get
everything that really countsmemory and processor - without
the ancillary components.
Functionally, the NAKED MINI is
identical to Computer Automation's
existing machines. None of the previous line's superb features have
been sacrificed. The 16-bit NAKED
MINI, for example, still gives you
hardware multiply! divide as a standard item. Moreover, all machines
offer direct memory channels , vectored interrupts, and 32K of addressability. Because the software and
I/O interface are compatible, all of
the options a nd program s for
Co mputer Automation's present
machines are useable with the
NAKED MINI.
For the systems designer , the
NAKED MINI means an opportunity to get full computer power and
greater design freedom at drastically
reduced prices. In all industries, this
innovative concept opens up new
application areas, with general purpose minicomputers replacing hardwired circuitry.
The NAKED MINI with 4K of
expand able memory is priced from
$1700 ($ 2400 for the 16-bit unit)
in 200-unit quantities. First deliveries are scheduled for this November.

LETTERS TO EDITOR
To The Editor:
Referencing your "Astrogyp" article in October's MODERN
DATA: You may have seen a different advertisement for "Zodiascope" then the one I've enclosed.
However, please note that the picture shows a Hewlett-Packard
2000A computer and a HewlettPackard 3030G tape drive, not a
Honeywell System.
My compliments on an otherwise beautifully written and
timely expose.
Frank Del Monte,
Leasco Response, Inc.,
Washington, D.C.
To The Editor:
At the recent A.C.M. meeting in
New York City, F.B.I. agent D. R.
Roderick described the steps taken
to prevent National Crime Center
(N.C.I.C.) data ("wanted" lists, stolen cars, and in the future , arrest
records)
from
getting
into
unauthorized hands. He also stated
that the security of the N.C.I.C.
system primarily rests with the local police authorities - the intended users of the system.
It is, however, not clear to me
what is to keep an insurance agent
who is also a deputy sheriff (or a
moonlighting policeman) from accessing the system for private gain.
When I presented this hypothetical situation to Mr. Roderick, he
suggested that the F.B.I. may deny
service to those authorities who
misuse their responsibilities.
As a private citizen as well as a
computer professional, I believe
that this is insufficient. Since the
"Secrecy" Clause of the Communications Act of 1934 makes it a
crime to divulge this sort of information outside the system, the
F.B.I. should vigorously prosecute
unscrupulous law enforcement ofMODERN DATA/ April 1971
ficials who misuse N.C.I.C. data to
the same extent that it would prosecute any other individual found
to 'be making unauthorized use of
this data.

To The Editor:
Your F ebruary T echnology Profile
on line printers prompted me to
ask you this question, since nobody
else seems to know the answer:
Does anybody make a printer with
a little processs-control machine attached that will automatically re-'
ceive the output of the printer,
burst it, fold it up, stuff it in an
envelope, seal the envelope, address it, and toss it in a mail bag?
And if not, why not? One of the
small lunacies of the computing
world today is the number of
people I see who are "slaves to a
computer." In this case, it is the
anonymous warm bodies who run
around attending to the computer's
digestive functions. What an appalling job! Isn't this what the
computer was supposed to rid us
of in the first place?

The Editor's Reply: There are, of
course, a number of automatic
bursters, stufJers, sealers, and
stampel's on the market. But if we
read you cOl'rectly, you want an online system that collates and addl'esses as well - in one continuous

It takes
sp~cial dqta terminals
to fill special data
terminal requirements.
And special data terminals are our specialty.
Since we make most of the components that go into
data terminals anyway, we can design and make the whole
terminal , to meet your custom requirements.
And you 'll be happy to hear that our typical turnaround
for a prototype is normally less than four months.
If you prefer to put your terminal together yourself,
we can supply you with do-it-yourself components such as
card readers, switches , scanners, logic , indicator
lights and all the connectors you 'll ever need .
But you 'll save time and money if you let us do the whole
thing . And we ' ll treat it as special as you would.

NEWS ROUNDUP
CPMA PROTESTS
TARIFF 260 AMENDMENT
The Computer Peripheral Manufacturers Association (CPMA) has formally protested to
the Federal Communications Commission
against what it considers to be "unfair and
monopolistic practices" on the part of the Bell
System Operating Companies. The protest is
in regard to an announced amendment application to Tariff 260 which includes a requirement that protective devices must be used on
private leased line data communications service beginning on July 1, 1971.
CPMA's arguments that th e proposed
amendment would result in an increased and
unnecessary financial burden to both end
users and manufacturers are several: ( 1 )
There is no clear past evidence supporting the
need for special protective devices; (2) The
protective devices have not been defin ed
either operationally or functionally; (3) The
devices could restrict the use of equipment
presently available from independent manufacturers which is technically superior to
comparable Bell System offerings.
To the first point, CPMA points out that private leased line service has been successfully
provided for years by the common carriers
without the use of protective devices. Furthermore, notes CPMA, the profit margin attained
by the current tariff appears sufficiently attractive to have warranted the emergence of
competitive carriers.
LATEST PRIVACY INVASION
Latest item in the controversy surrounding government-maintained data banks involves an alleged
directive requiring certain upper-level government
employees to take part in psychological, "encountertype" sessions. In an address to a Dickenson College
Public Affairs Symposium entitled "Privacy and
18
CPMA believes that the mystery surrounding how the device will operate and what it is
supposed to prevent is in itself enough reason for objecting to the tariff amendment. Not
only could the device be designed to obsolete
many current in-service equipments, but it
could also end up doing exactly what it is
alleged to prevent, i.e., degrade service rather
than improve it. In any case, the requirement
for the device "must be interpreted as punitive
to independent equipment manufacturers"
since it would force data communications
users "to return to the Bell System as a source
of supply" in the face of the less expensive and
higher-performance equipment presently offered by Bell System competitors.
The Washington, D.C .-based organization
dramatized this last point with an allusion to
the Bell System's aura of pre-eminency in the
data communications fi eld : "The CPMA seriously doubts that AT&T is the only source of
advanced technology in the communications
industry. In fact , the implementation of equipment that allows data communications speeds
in excess of 2400 bits per second on Tariff 260
lin es has just begun by the Bell System. On
the other hand, technically superior equipments which operate to speeds of 9600 bits per
second have been available from independent
manufacturers and successfully used for over
three years ." It is precisely such state-of-theart equipments, claims CPMA, that would
likely be made unusable by technical problems resulting from the as yet undefined protective device.
th e Constitution," Senato~ Sam J. Ervin ( D-N.C.),
whose Senate Subcommittee on Constitutional
Rights has been probing such excesses, stated that
"A record of refusal to cooperate with this program
is grounds for a charge of disobedience, all of
which is reduced to the minimum for cold computerized entry in personnel data banks, with no
indication of the justice of the employee's protest
against unwarranted privacy invasion."

EXPORT VIOLATIONS The Dept. of Commerce
has imposed fines totalling $10,000 on Calcomp
N. V. of Amsterdam , California Computer Products'
Dutch distributor, for violations of export control
laws. The Netherlands firm was charged with having
made sales to customers not previously approved by
the Office of Export Control in the Department 's Bureau of International Commerce (BIC) . However, BIC
said no sales were made to parties prohibited from
dealing in U. S. goods, there was nothing to indicate
security violations , and no employees of the California company were involved. Half the penalty has al ready been paid, and BIC indicated the balance may
be waived after further examination.
Although the 1971 -75
TRADE WITH HUNGARY trade accord between Budapest and Moscow should
result in more scientific cooperation between these
countries, Hungary 's interest in the products of
Western technology is not expected to slacken. The
Journal of Commerce reports that little information
has leaked out so far on Soviet-Hungarian collaboration in the computer field. In fact, the paper said,
"Hungary has been West to acquire such technology
and likely will do so again due to the East-West
know-how gap."
UK DP IMPORTS UP - United Kingdom imports of
computers in 1970 continued to diverge quite rapidly from exports , leaving imports further ahead
than ever before . According to The Financial Times
of london, 1970 exports were up 45 percent over
1969, while imports were up 52 percent in the same
period . The main reason for the discrepancy is believed to be the import of large amounts of peripheral equipment to be used with imported or
home-built computers, rather than the import of
computer systems themselves. The situation in Britain is unlikely to change very much until after 1972,
when the effects of the installation of new manufacturing plants for computer peripherals in Britain by
U. S.- based companies begin to be felt.
UNDERWEAR VS. HARDWARE - A computer expert
at Leeds University in England reports that static
electricity generated by women 's nylon underwear
can cause computer circuitry problems. Harry Eastwood , Manager of Leeds' computer laboratory, notes
that "the more delicate new computers are particu larly prone." Some firms using computers, he said ,
have asked their women to wear cotton underwear
and not nylon.

BRITISH RAILS - British railroads are expected to
invest about $24 million by 1975 on a centralized
computer service expected to be the largest multiple-access installation in the United Kingdom. The
Financial Times of London reports that the central
installation will service the various departments
within the organization (freight, manpower allocation, passenger service). as well as the normal payroll and management functions included in business
computing. Savings of up to 15 percent are predicted in some areas.
COMPUTERS IN INDIA - Computers are playing a
major role in accelerating India 's development , The
Asian Student reports . India is not only manufacturing computers but is exporting them to developed
countries. IBM , for example, exports computers valued at over $2 million annually to 46 countries from
India. There are currently 100 computers in the
country, one-half of them added since mid-1967.
The use of computers is credited with providing jobs
for some 20 ,000 Indians working in DP establishments. It was estimated five years ago that by
1975 India will need some 500 medium-size and
5,000 small computers. Most peopl e today con si der

LARGEST DEFENSE T-S SYSTEM - Honeywell announced
Air Force acceptance of a computer system that will be the
Defense Dept.'s largest time-sharing network when it is
fully implemented this November. The system, which the
Air Force calls CREATE (Computational Resources for Engineering And Simulation, Training and Education), is centered at the Air Force logistics Command headquarters at
Wright-Patterson Air Force Base, Dayton, Ohio, and currently links 39 remote terminals to 10 Air Force bases from
coast to coast. By November, 94 terminals will be hooked
up with the central site at Wright-Patterson . J. J. Renier,
vice president of Honeywell's Data Systems Operations,
said the system's major function is to provide computational
services for approximately 5,000 engineers and logisticians
who plan and control the Air Force's vast industrial-type
supply network. Renier described the current hardware
configuration as a dual 615 with four remote-batch
GE115s, two graphic display terminals, and 13 Teletype
terminals located at Wright-Patterson. The two multiprogramming/multiprocessing central processing units have
256,000 words of memory, six characters per word, and
there are approximately 480 million characters of removable disk storage and a billion characters of on-line archival disk storage.
PROGRAM PATENTS - Although recent court decisions
have held certain computer programs to be patentable, the
requirement that inventions be non-obvious will probably
prevent the majority of programs from being patented.
"This," says Patent Commissioner William E. Schuyler, Jr.,
often "causes businesses to resort to secrecy," producing a
situation "certainly not conducive to progress." Commissioner Schuyler believes a new system to protect inventions
of lesser importance should be created to supplement the
present patent system. "Japan, an industrial power to be
reckoned with now, not to mention the years to come, is
just one of many foreign industrial powers which already
have similar systems in operation," he said.
HELP FOR JOBLESS - Speedy enactment of legislation to
curb unemployment of jobless scientists and engineers by
creating up to 200,000 jobs has been called for by Sen.
Walter F. Mondale (D. Minn .), one of the sponsors of the
Emergency Employment Act. Sen. Mondale said, "It is
ironic that we have permitted thousands of scientists and
engineers to join the ranks of the unemployed while many
of our public programs are desperately in need of additional technological input and manpower. We have ample
evidence that Defense and aero-space industry skills can
be adapted to civilian technology." One area hardest hit
by the layoffs of skilled scientists and engineers, he said,
was the computer industry.

NATIONAL SCIENCE DP CENTER - Congressman R. C.
Puc in ski (D. 111.) has re-introduced legislation to establish a
National Science Research Data Processing and Information Retrieval System. The bill (H.R. 1040) was referred to
the House Education and labor Committee. It is aimed at
avoiding unnecessary and costly duplication in scientific research and assuring quick access to science research data.
The nationwide system would "include close voluntary cooperation with, and utilization of, on a contract basis wherever practical, all existing science research DP and information retrieval facilities in the U.S." The system would be
"available to any scientist or researcher, either privately,
publicly, or self-employed, through an appropriate communications network ."
HIGHWAY RESEARCH - At the recent annual meeting of
the Highway Research Board in Washington over 3,000
persons heard reports on the application of computers to
highway problems. C. V. Kroll of the Cornell Aeronautical
laboratory (CAL) reported on a modified version of the
Bureau of Public Roads-CAL computer simulator of automobile dynamics, which is used to investigate driver behavior
in emergency "pre-collision" situations. CAL researchers
E. Donald Sussman, Robert C. Sugarman, and James B.
Knight, in a study of driver alertness, concluded that the
rate of steering wheel corrections made by a driver decreases linearly with time over four hours and, on a persubject basis, there is a significant negative correlation between position error and steering wheel correction
frequency.
MAG TAPE CASSETTES - A digital magnetic tape cassette program is being conducted by the National Bureau
of Standards in cooperation with the American National
Standards Institute's Committee on Computer and Information Processing (X3). The program will include development
and maintenance of a national amplitude reference tape
for cassette applications, and the development of a related
system for evaluating the characteristics of digital cassette
tapes. Initial efforts will be directed to the 150-mil-wide
tape employed in "Phillips-type" cassettes.
IN BRIEF
National Science Foundation hos requested $17,500,000 in fiscal 1972

spring. The 23~-year old company
employed a peak of 108 persons
when it exhausted its operating
capital early last November, after
promised
long-range
financing
failed to materialize. The entire
work force was furloughed November 13, but most of the employees
continued to work through January without pay. Warkenton said
COl executives were continuing
their efforts to help employees secure jobs elsewhere. About 35% of
the work force has relocated in
other companies.
The employment picture for engineers and scientists ended on a
gloomy note in 1970 with a further
downturn in D ecember. The December figure, 35.3, represents still
one more record low in the ten-year
history of the Engineer/ Scientist
Demand Index maintained by
Deutsch, Shea & Evans, New York
manpower agency. It was a 2.6 drop
from November. By comparison,
the 1969 D ecember figure was 80.3
and the highest December on record was 1965, when the ESDI
showed 169.0.

Ltd. ; Geoffrey H. Bennett, vice president of finance; Jeffrey M. Donahue, executive vice president, Consolidated Computer International, Inc.
BACKGROUND:

PRODUCTS /SERVICES :
Consolidated
Computer's
Key-Edit system is a shared-processor system designed to provide time-sharing of multiple key-station operations for simultaneous editing and data
preparation. Hardware consists of a high-speed
computer, mass storage devices, a control console,
and up to 32 keystation terminals. Options include
line printers, card readers, paper tape equipm'e nt,
and communications devices.
Consolidated Computer's time-sharing system,
deSignated the 2100, accepts up to 16 termin als
Simultaneously for conversational time-sharing.
Employing the Basic language, the 2100 system is
primarily for use as an in-house system by large
companies.
30
Since installing its first KeyEdit system in Canada in late 1969, the company
has become a significant force in the shared-processor data-preparation marketplace. By January
1971, the company had installed nearly 100 Key.Edit systems with over 1,000 keyboards attached,
as well as a substantial number of time-sharing
systems. Revenues for the year ended D ecember
1969, the first year of Key-Edit shipments, were
$650,000.
CURRENT POSITION:
OUTLOOK: According to Consolidated's marketing
analysts, about 300 of all makes of shared-processor data-preparation systems were installed worldwide at th e end of 1970. By the end of 1971 cumulative industry installations are expected to
increase 133 percent to 1000, valued at $100 million. Annual industry shipments of $200 million
are anticipated by 1973 when more than 4,000 systems will have been installed. The company believes there are currently about 500,000 keypunch
machines and 30,000 key-to-tape devices installed
worldwide. It is possible that 15 to 20 percent of
th ese may be converted to shared-processor systems over th e next four yea rs.
FINANCIAL SUMMARY: Consolidated Computer, the
first company in Canada to manufacture computer
equipment, has been granted financin g b y th e Canadian Governm ent of 90 percent of its requirements up to $12 million . In addition, Canada is
underwritin g 50 percent of the company's development costs. In 1970, Consolidated announ ced a
3-year sales agreement valued at more than $50
million with International Computers, Ltd. London .
Most significantly, the company recently announced th e form ation of Consolidated Computer
Leasing, in conjunction with Ford Motor Credit
Company. This is an important consideration in
evaluating the following operating statistics,
which do not reflect sales made to the new leasing
organization. By the end of 1970, Consolidated
had equipment with a sales value of over $10 million in the field.

Every so often we find ourselves biting our ton gue
(though not so often, we suspect, as our patient
publisher) over things said in this column. In our
January commentary on the state of the industry,
we bemoaned the lack of truly innovative and
well-conceived new product or service offerings.
This month we are pleased to report that innovation is alive and well in at least two cases.
In the first, Western Union continues th eir transition from singing delivery boys and Candygrams
to the Communications Age with their very attractive service offering, Datacom. In the second case,
Para dyne has greatly cost-reduced and Simplified
remote batch or remote job entry with their new
peripheral interface extender. We commend both
of these to your attention.

second advantage is that the common carrier bears
end-to-end responsibility for the channel, and this
would not be the case with COAM (Customer
Owned And Maintained) multiplexers. A third advantage is that the service is offered on a onemonth minimum basis. Hence, system changes
which might be unpleasant because of owned but
unamortized multiplexing hardware, can be made
more easily.
The service also includes some provisions for
joint usage. "Authorized users" may be designated
by the "customer," and there is no surcharge as in
the case of tariffed joint use. An offsetting constraint is that the customer and authorized users
must be "in the same line of business." Counter to
tariffed joint use, however, traffic may flow between users. That is, if A & B are authorized users
each may send to itself and to each other.
'
In fact, th e only apparent drawbacks are the
need to go leased line to a terminal city and a
restriction that there be only one speed-code system per service. That is, the speed-code system of
TABLE 1
WESTERN UNION'S DATACOM SERVICE
Last fall Western Union introduced a new and interesting service called Datacom, offered under
Tariff FCC 257. The service is the provision of
narrowband channels derived from a voice channel through the use of channel subidivision (multiplexing) equipment. Datacom is offered on a
two- or three-point basis in any of the 45 major U. S.
cities designated in the tariff as "terminal" cities.
This means that service can be provided between
any two terminal cities, plus (optionally ) any
other one city intermediate to the first two. Customers with terminal locations in non-terminal
cities may access th e service by leased line to the
nearest terminal city. For example, a customer
with a CPU in Wilmington, D el. and a number of
terminals in Providence, R. I. could go leased line
from Wilmington to Philadelphia and Boston to
Providence, and Datacom between Philadelphia
and Boston.

MODERN DATA/ April 1971
all sub-channels in a given two- or three-point service must be one of the four combinations shown
in Table 1.
The leased -line-to-terminal-ci ty requirement can
be traded off against the advantages of common
carrier maintenance, end-to-end responsibility,
and month-to-month rental. The single speed-code
requirement should not be much of a problem.
The costs consist of some conventional interstate charges plus fe es related to the multiplexing.
Conventional interstate rates apply to the airline
mileage between the terminal cities for the fullduplex multiplexed voice channel, and to the service terminal ( and station arrangements for 110 to
150 baud channels ) for each narrowband channel
provided per terminal city. Only one such charge,
however, is applied per narrowband channel p er
terminal city if the customer's terminal is within
the city's corporate limits. Two sets of charges (as
well as the charge for a voice channel service terminal ) would probably b e required if the mux
were COAM . Furthermore, all narrowband service
telminals in a terminal city after the first are
charged at the less expensive "each additional"
rate. The multiplexing fees are a flat $400 per
month for any two-point service; $600 p er month
for a three-point service. Finally, a per-channel derivation fee is charged according to the schedule
shown in Table 1. These fees are per Datacom
service. If a customer and an authorized user each
needed seven, 75-baud channels, they would pay
at the fourteen channel rate.
PARADYNE'S PERIPHERAL EXTENDER
Paradyne Corp., Clearwater, Florida, recently announced a very interesting, unique, and attractive
device for use in data communications. For originality in concept, it is very impressive and stands
out amongst the chaff of new product releases.
Notwithstanding all that hyperbole, it also seems
to have economic appeal.
Paradyne's new device, called th e PIX-600 Parallel Interface Extender, looks and acts like a peripheral controller. However, it is designed to operate its peripheral device over a communications
link. Fig. 1 is a block diagram of the system. Its
beauty is three-fold. In terms of hardware, it combines the communications controller, data set
adaptors, and high-speed modem in one unit; and
the remote terminal can be a standard p eripheral
device instead of a full -blown remote terminal.
From a software point of view, the remote terminal now looks like any locall y resident p eripheral device. The only difference is that the peripheral seems to operate much slower because of
the throughput ceiling imposed by th e communica tion channel. Opera ting at a data rate of 4800

bps, the PIX-600 appears as a 600 byte-per-second
p eripheral. Finally, from an operating point of
view, the potential throughput rate is substantially
improved over many other systems. This is because of two factors , First, the communication
sub-system is self-contained within the Paradyne
equipment. Hence, the sub-system can block data
for optimum transmission efficiency without regard to the blocking characteristics of the terminal. ( The effect of optimum block length on
throughput is discussed in Saul Stimler's article on
Page 68 in this issue.) The second factor in improving throughput is Paradyne's use of a simultaneous reverse channel for conveying ACK/NACK,
which eliminates turnaround time on a dialed-up
connection.
Actual line transmission rate is 5112 bps. The
difference between 4800 and 5112 is allocated to
error-detection coding and to overhead characters
for line coordination/control. In a noise-free channel, then, the data throughput is a full 600 bytes/second. Paradyne's press releases guarantee no
errors attributable to the communication environment. We deba ted that one with their marketing
VP, James Wylie, giving him a chance to qualify
it. H e backed off only to the still-remarkable position that the PIX·GO O would produce an undetected error rate of 1 x 10· 1~ on a "worst-case" channel. That is, for a system operating at 1 x 10'°, he
felt th ey would operate at 1 x 1O. 1~ on the same
channel. Of course, th e cos t of this is throughput
degradation , which h as to be assessed for all competitive systems in any individual application.
In certain systems ( probably those with few remote terminals requiring simultaneous access), the
total hardware package of $6000 per end, $12,000
per link, will be very cost-effective. Overlaid on
this, however, are th e savings in core and software: no telecommunications access m ethod, and
no special terminal handlers. Being a more familiar
I / O system, it should be infinitely easier to program and to cope with bugs and operating problems. Even in systems requiring "several" simultaneous channels, the $6,000 price will be attractive
compared to the $5000-$6,000 necessary for 4800
bps modems alone.

Hardware, software and communications systems
One new instrument offers these combined
capabilities ... The Spectron Universal Monitor
If you produce, install or service data communications
hardware or software, our
Universal Monitor could be
your most helpful tool. It
will save time and help you
increase accuracy, regardless of your particular area of interest.
The Universal Monitor offers these advantages because it provides
a character-by-character hard copy record of everything that is sent
and received over the data link. Which means it not only points out
errors in hardware, software or lines, but also enables you to determine precisely what is causing these errors, and why. So less time is
spent tracing problems, and higher accuracy is far easier to come by.
The Universal Mon itor is the only transmission test set that can be
conveniently operated on-line. As an aid to field service technicians,
for example, you 'll find it a dramatic improvement over present trialand-error methods of trouble-shooting .
Other features include the ability to: accommodate all line coordination systems ; monitor any code and speed up to 7200 bps; work with
synchronous or start-stop transmissions; and operate full- or halfduplex. That's the Universal Mon~
itor from Spectron. We made it do
more, so you'd have to do less.

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
90
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.

problems finding, training
and keeping keypunch
operators, maybe we have a
solution. The MDR Series
Document Reader. It gets the
job done when you want it,
how you want it, and at a
cost far lower than you are
now paying.

conversion to machine
language can be achieved
automatically. If your system
is built around the IBM-029,
our reader can easily convert
pencil marked data to a deck of
punched cards. Automatically.
Without error. Without a
keypunch operator.
