The sixteen, 16-bit registers on-chip can be used as program counters, data pointers or for data storage. One register serves as a built-in data pointer for DMA, an unusual feature among available microprocessors. The traditional CMOS low-power requirement of this microprocessor (60 mW typically at (4081 247-8940 Copyright © 1975 by Microcomputer Associates Inc., All Rights Reserved. M.R. lemas, President. Published monthly. Subscription $28.0Q per year, overseas $40.00 per year. DARREll D. CROW, Editor; LILLIAN lAU, Associate Editor; PATRICIA L. DREISBACH, Circulation Editor; RAY HOLT, Applications Technical Advisor; MANNY lEMAS, Applications Technical Advisor. 2MHz) permits use of a single unregulated power supply of 3 to 15 volts. Supply voltage tolerance of CMOS permits use in batterypowered systems, making the CDP1801 particularly appropriate to automotive and portable equipment applications. CMOS noise immunity, or tolerance to ambient electrical interference, typically amounts to 45% of supply voltage. The CDP1801 is able to operate over the full temperature range of -55° to +125 0 C. The Microkit is a hardware support kit containing the CPU, lK RAM, 512 words ROM, space for additional memory and user-designed interface cards, I/O decoders, and I/O interface for a TTY or other terminal, and power supply. The kit is thus a complete prototyping system. A Microkit with a resident editor, assembler and debug board option with a user-supplied terminal provides a complete, independent system for producing debugged programs. More powerful software development aids are available that offer assembly, editing, simulation and debugging. This program is available either on the General Electric timesharing network or as a FORTRAN IV tape for installation on an interactive computer. A microprocessor manual, describing the CDP1801's architecture, instruction set, I/O interfacing, and programming techniques is available as well as manuals on the various software design aids. The CDP1800 family is now available from stock, with the CDP1801 full-voltage (15V) chips available at $56 and the CDP1801C 5V chips at $40 in single quantities. IBM ENTERS MICROCOMPUTER MARKET (from page 1) The memory is expandable from 16K to 64K in 16K increments. The purchase price ranges from $9,000 to $20,000 depending on memory and options. The CPU card consists of a single chip MOS microprocessor whose architecture is similar to the company's system 360 mainframe. The unit is a stored program processor and implementation of APL and BASIC is made in a single 48K ROM chip. A 3M-type cartridge in the tape unit can store up to 204K characters of data and permit exchange of data and programs between cltI; PO BOX 1167, CUPERTINO, CA 95014 • Volume 2, Number 41 October, 1975 3 MICROCOMPUTER DIGEST other 5100 Portable Computers using the same programming language. A standard feature provided on the 5100 permits users to attach external TV monitors for displaying information to~groups in large offices, conference rooms and business work areas. Hard copy output is provided from the IBM 5103 optional printer at 80 cps in a 132-print position matrix~ The printer handles single sheets, multiple copies or continuous single or multipart paper. The 5100 CRT features a 16 x 64 display which includes all the special characters used in both APL and BASIC. ROCKWELL &NATIONAL pP 2ND SOURCE PACT (from page 1) Charles V. Kovac, vice president and general manager of Rockwell's Microelectronic Device division, and E. Floyd Kvamme, National's vice president and general manager of the Semiconductor division, jointly announced the agreement in New York on Sept. 3, 1975. The agreement covers all current microprocessor products of each firm; provides options on second-sourcing modifications, and establishes machinery for periodically reviewing new microprocessor developments toward possible additional agreements. Termed a "supported, alternate source" agreement, the pact is believed to be one of the most comprehensive consummated to date in the microprocessor field. In addition to establishing competitive second sources for their microprocessors, the agreement provides each company with the broadest microprocessor line in the industry, ranging from 4-bit, low cost systems to high performance 16-bit systems. Rockwell is in volume production with its PPS-4 microprocessor and is beginning volume manufacturing of its PPS-8 system. Additionally, Rockwell has developed a modification of its 4-bit system, designated PPS-4/2, which the company descr,ibes as a "very low cost" design for electronic retail systems and process controllers. National was the first to offer a single chip 16-bit microprocessor, the PACE. The firm also has a bit-slice microprocessor, the IMP family, available in 8- and 16-bit configurations. National is ~lso developing (cont'd next page) (408) 247-8940 Copyright © 1975 by Microcomputer Associates Inc., All Rights Reserved. M.R. Lemas, President. Published monthly.

Each firm will provide the other with complete applications support for their lines, including extensive software documentation and training programs. Both firms also produce an extensive number of associated I/O circuits and memories and these are expected to complement each other's microprocessor lines. The agreement does not include the National FIPS microprocessor which is a second source device for Intel's 4040. The microprocessor market is estimated at $80 to $90 million for 1975, and is expected to grow to between $350 and $500 million by 1980. LSI-II CHIPS OPEN To THE PUBLIC (from page 1) The instruction set can be microcoded to emulate other machines, or the customer can design their own instruction set or use a standard instruction set that Western Digital will introduce shortly. The standard instruction set will be in a special minicomputer language similar to the one used by Data General. It will be supported by cross assemblers and other software aids. A PROM simulator will be provided to those customers that choose to develop their own instruction sets. DEVELOPMENT SERIES (from page 1) The 6902 CPU/TTY interface board incorporates the IM6100 microprocessor and all the necessary logic required to interface it to a standard TTY. The processor executes th.e !Same instruction set as the PDP 8/E. In addition, it provides a subset of the 8's omnibus signals allowing all regular programmed I/O transfers and program interrupt transfers for the PDP 8/E to operate without any hardware or software modification. The DMA structure of the IM6l00 is similar but not compatible with that of the PDP 8/E. The only other deviation from PDP 8 compatibility is the unavailability of the Extended Arithmetic Element (EAE) and the User Flag (UF). The 6901 4K x 12 CMOS RAM board provides the designer with a non-volatile system mem- cI~~ PO BOX 1167, CUPERTINO, CA 95014 • Volume 2, Number 41 October, 1975 ory. Three penlight nickel cadium batteries are included on the board to power the memory when the main supply is turned off. This feature frees the designer from reloading a program whenever he wants to work on it. It also protects against power failure. The 6900 system features an extremely versatile control panel (functioning identically to that of the PDP 8/E). The 6903 is a dedicated, completely independent control panel with its own memory. Unlike most microcomputer control panels, Intersil's requires no main memory to operate. The user system does not "see" the control panel; consequently, the panel can be connected or disconnected at will. The 6903 is also supplied with a PROM containing a bootstrap loader for a paper tape reader, and other software can be implemented very easily since any software resident on the control panel is executed using RAM on the panel, leaving the main memory undisturbed. This "transparent" control panel should be extremely useful in maintaining microprocessor based production systems with limited control panels. One control panel would be enough to service many dedicated systems. All of the 6900 series cards run off of a single +5 V supply, with a minimum system consisting of a 6901, a 6902 and a 6903 drawing around 2A. The cycle time of this system is 1 us, thus a memory-to-accumulator add (TAD) instruction is executed in 5 us. The introduction of several new cards is planned by year end. A 4K x 12 NMOS RAM board will provide an inexpensive, but volatile main memory. Since only 4K words of memory are directly addressable by the processor, a memory extender board will be available. This option allows expansion of the main memory from 4K to a maximum of 32K. Two boards will facilitate program storage. The first is a high speed paper tape reader/punch interface. The other is a DEC compatible floppy disc interface, using standard IBM formatting. The IM6100 is part of an all-CMOS family of Intersil ICs. Already available are the IM6508 1024 x 12 ROM and the IM6403 UART for serial interface applications. Intersil plans to introduce the IM6l01 Parallel Inter(cont'd next page) (4081 247-8940 Copyright © 1975 by Microcompute,r Associates Inc., All Rights Reserved. M.R. Lemas, President.

An all-CMOS microcomputer system offers several advantages over other designs. A single unregulated supply between +4 and +11 V is all that is required to power such a sys~ tem. A CMOS microcomputer with the IM6100, lK of RAM, lK for ROM, a UART and a PIE draws only 40 mW at +5 V. Another cost saving feature of the IM6100 is the inclusion of an onchip oscillator. An external crystal is the only component required to clock the processor. A unique application area is that of telephone line powered instruments/peripherals. The telephone line provides about 40 V of 20 rnA, more than enough to power a CMOS system. Line powered microcomputers may also find application in telemetry and security systems as well as in the telephone system itself. The designer will have no problem in finding software for the 6900 system. Practically any program that will run on a PDP 8/E will run on Intersil's development system. DEC maintains a program library of over 700 programs for the 8/E, ranging from assembly language routines to operating systems. DEC's sophisticated operating system, the OS/8, will run on the 6900 system without modifica~ tion. Three versions of FORTRAN IV and two versions of BASIC are also available. All DEC programs are thoroughly debugged and documented. The designer can also write his own routines in widely used PDP 8 assembly language and assemble it using one of several assemblers available. T~e basic 6900 board set with a 6901 4K x 12 CMOS RAM card, a 6902 CPU/TTY card and a 6903 control panel is priced at $3050. Individual card prices are $1860 for the 6901, $775 for the 6902, $765 for the 6903, $254 for the 6904 (INT), $49 for the 6905 (wirewrap), and $95 for the 6906 (extender). Deliveries are within two weeks. WESCON-MICRO WRAP 'UP WESCON 75, the 24th annual Western Electronic Show and Convention, was held September 16-19 at Brooks Hall and Civic Auditorium in San.Francisco, CA. This year's show gave evidence to the industry's recovery following an extended economic recession. The entire cit!; PO BOX 1167. CUPERTINO. CA 95014 • Volume 2, Number 41 October, 1975 WESCON exhibit space was sold out weeks in advance to more than 300 U.&. and overseas manufacturers who demonstrated their new equipment in 500 displays. Attendance was officially tagged at 30,300, WESCON's highest since 1969, and the highest ever for a WESCON presented in San Francisco. The show was highlighted by numerous dazzling displays of microcomputer products, which included the following. General Instruments kicked off their marketing of the now commercially availafule CP1600 microprocessor with the introduction of the Series 1600 Microprocessor System.

The family includes the 6501 and 6502 microprocessors which are pin compatible with the M6800. WESCON was the first u.S. public display of Panafacom's new three chip 16-bit microprocessor. And right on the heels of Intersil's introduction of the IM6100 microprocessor, Douglas Electronics Inc. introduced the LSI80 built around Intersil's IM6100. The microcomputer looks like a PDP- 8 to us er' s programs and peripherals. The LSI-80 is available in either system or card form. The CPU board is priced at $350. Representatives from Fairchild, Motorola, RCA, General Instrument, Rockwell, Intersil, MOS Technology and MOSTEK demonstrated their development systems and microcomputer cards at the overcrowded booths of Semiconductor Specialists, Hamilton/Avnet and Elmar Electronics. The $249 JOLT microcomputer was demonstrated by Microcomputer Associates. The kit is a new fully-tested microcomputer complete with an on-board DEbug MONitor (DEMON) program. The JOLT CPU includes an 8-bit MOS Technology 6502 microprocessor, which requires no clock, can directly address 65K of memory, has two index registers, 58 instructions with 11 addressing modes, two interrupts and includes both· single step and address halt capability.

RECENT LITERATURE i'When To Use Higher-Level Languages -In Microcomputer-Based Systems" Jim Gibbons, Ryan-McFarland Corp. Electronics August 7, 1975 This article discusses the use of compilers versus assembly programming to generate code for microcomputers. The author feels that the time is quickly approaching when it will be cheaper to develop a compiler and hand it to the customer along with the microcomputer for the customer to develop his own program. He maintains that excessive costs in assembly programming cannot be justified in applications where only a few products are produced. A cost analysis of using a compiler versus an assembler is given alOng with a few suggestions on designing a compiler for microcomputers. "Basic uP Test To"ol: The Portable Debugger" Jim Barnes, Verne Gregory, Motorola Semiconductor EDN August 20, 1975 Tpe authors have described a very basic low cost microprocessor tester that can be used even when the microprocessor is in the user's product. The particular tester described was used for the M6800, but the principles applied can be easily adopted to any microprocessor. The article concerns itself mostly with features needed for such a tester along with limitations imposed by low cost systems. This particular test instrument was constructed with less than $50 in parts. "European Industrial Robots" Frost & Sullivan, August 19~5 This lengthy report analyzes the European market for current and advanced industrial robots from 1975 to 1985 and contains infor- cI~; PO BOX 1167, CUPERTINO, CA 95014 • Volume 2, Number 4 I October, 1975 18 MICROCOMPUTER DIGEST mation obtained through interviews, questionnaires, product data and R&D data from laboratories in the U.S., UK and Japan. The report identifies market areas, robot applications and machine evolution. Microcomputers are noted to be used in the artificial intelligence of these systems, however it is not a discussion of design criteria. The report is useful for identifying possible microcomputer applications in future robots. "Using A Microprocessor: A Real-Life Application Part 1" . James D. Logan, Paul S. Kreager, Washington State University Computer Design September 1975 A very enlightening article that presents the complete implementation of a microcomputer-based system. This is the first of two parts and describ,es the hardware required, along with the microcomputer, the interconnections and functions of other components. Although the article is based on the M6800, the details on its implementation and accompanying description of how problems encoun-:: tered in its development were overcome should prove helpful to those developing their own systems, whether based on this microprocessor or on others. "Design Your Own Microcomputer By Using Bipolar/LSI Processor Slices" David C. Wyland, Monolithic Memories Electronic Design 20 September 27, 1975 An excellent article describing the design of a l6-bit microprogrammable microcomputer that uses 24 ICs. It has an instruction set of 18 commands, cycle time of 300 ns and instruction execution time of 0.9 to 1.2 us. Mr. Wyland's discussion centers mostly around microprogramming the bipolar slices. The particular chip used in the example is MMI's 6701 4-bit microcontroller. . # # # # Check to make s·ure you have entered your subscription.

's new517-page electronic industry econometric forecast. The upsurge should be fe£t by nearly all sectors in the electronic industry. Briefly: o Military electronics should grow 7.6% in 1976 with a significant decline in 1977-78, o Industrial electronics should begin to grow in 1976 to wind up the year with a 16.48% increase, (408) 247-8940 Copyright © 1975 by Microcomputer Associates Inc., All Rights Reserved.

DREISBACH, Circulation Editor; RAY HOLT, Applications Technical Advisor; MANNY LEMAS, Applications Technical Advisor. 21 MICROCOMPUTER DIGEST o Instrumentation should show a 12.7% growth, o Telecommunications will remain weak in the first part of 1976, o Microcomputers and minicomputers should . finish 1975 with a 10% increase to be topped by a 30% growth in 1976, o No growth in medium mainframes are expected, o Large frame computers should increase 8%, o Business/retail electronics should recover s.tronglY by the fourth quarter of 1976, and o IC sales are projected to increase by $75 million to a total of $550 billion for 1976. Although Gnostic Concepts reports a strong growth for 1976, the forecast does issue a warning that real growth would probably disappear in 1978, reflecting another recession and a return to double-digit inflation. EUROPEAN MICROCOMPUTER USAGE Microcomputer usage in Europe, at a $10 million level in 1974 will explode 60-fold to become a $600 million market by 1984, according to a new study by Frost & Sullivan, Inc. It was noted that cumulative shipments over the decade will tally $2.5 billion. Of that total, microprocessor components will account for $1 billion; memories for $850 million with ROM memories at 29%, RAM memories at 71%; I/O interfaces for $550 million; and other ancillary circuits for $75 million. The two-volume, 622-page study concludes that the microcomputer market is currently dominated by u.s. designs, but the first European and Japanese units are now becoming available, with:the Japanese companies, in particular, promising to offer serious competition in Europe after 1975. BRITISH COMPUTER SALES UP The U.S. Chamber of Commerce has reported that computer and related equipment sales in Britian were $1 billion for 1974 with an expected 15% increase forecasted for 1975. Exports were $505 million and imports were $830 million. The minicomputer and microcomputer are expected to grow about 20% annually.
