    Oral History Panel on the Development and Promotion of the Zilog Z8000 Microprocessor Moderator: Michael Slater Panelists: Federico Faggin Bernard Peuto Masatoshi Shima Ralph Ungermann Recorded: April 27, 2007 Mountain View, California CHM Reference number: X4022.2007 © 2007 Computer History Museum Michael Slater: We have with us today [April 27, 2007] four people who were involved in its [Zilog Z8000 microprocessor] creation: Ralph Ungermann, Bernard Peuto, Federico Faggin, and Masatoshi Shima. We’ve heard about the backgrounds from Shima-san, Federico and Ralph in the previous tape [oral history by the Z80 team], so we’ll start with Bernard. Could you tell us about your educational background, your experience before you came to this project? Bernard Peuto: Yes. I was born in France where I got an engineering education in radio and in computers in 1967 and 1968. I came to Berkeley to do a Ph.D. In 1969, I had my Master of Arts from Berkeley in computer science and I passed my prelim. I went back to do my military duties and then I came back and got a Ph.D. in computer science in 1974. My dissertation was about memory protection, which will come back as a subject later. As my first job I joined Amdahl Corporation from 1973 to 1976. The reason I joined Amdahl Corporation was that Charlie Bass was sharing an office with me when he was an assistant professor at Berkeley and I was a Ph.D. student and Charlie Bass had a good friend of his that was working at Fujitsu so through that connection I was hired as a computer architect at Amdahl Corporation.

Chapter 3 Microprocessors in the 1970's The creation of the transistor in 1947 and the development of the integrated circuit in 1958/59, is the technology that formed the basis for the microprocessor. Initially the technology only enabled a restricted number of components on a single chip. However this changed significantly in the following years. The technology evolved from Small Scale Integration (SSI) in the early 1960's to Medium Scale Integration (MSI) with a few hundred components in the mid 1960's. By the late 1960's LSI (Large Scale Integration) chips with thousands of components had occurred. This rapid increase in the number of components in an integrated circuit led to what became known as Moore’s Law. The concept of this law was described by Gordon Moore in an article entitled “Cramming More Components Onto Integrated Circuits” in the April 1965 issue of Electronics magazine [338].

    Computer Development in the Socialist Countries: Members of the Council for Mutual Economic Assistance (CMEA) A.Y. Nitusov Köln/Cologne, Germany; Moscow, Russia [email protected] Abstract. Achievements of the East European Socialist countries in computing -although considerable- remained little known in the West until recently. Retarded by devastations of war, economic weakness and very different levels of national science, computing ranged „from little to nothing‟ in the 1950-s. However, full-scale collective cooperation with the USSR based on principles of equal rights and mutual assistance was aimed at increasing of common creative power. Centralised planning and ability to concentrate efficiently national resources on priority issues, state support for science and progressive educational system accessible for everybody played decisive role. The progress was impressive. Some (GDR) reached world‟s level in science and engineering such as some (in Hungary) – advanced computer education, programming and efficient usage and some (in Bulgaria, Cuba) starting “from zero point” turned into reputable manufacturers. In 1970-1990, 300,000 people as the united team of eight countries jointly designed and produced advanced family of compatible computers ES. Given general review also displays some important technical and organisational details. Keywords: Computer development, East European countries, computer family ES, free education, cooperation 1 Introduction Little was written abroad computer development in the East European1 socialist countries – partners of the USSR, during relatively long period, although some of their achievements were of considerable interest. The lack of foreign attention was primarily caused by natural desire to display first the own pioneer discoveries and most important inventions. The results of the East- European (outside the USSR) computer research appeared notably later than in the “great powers”, what could be another reason of “the silence”.

INTRODUCTION The ZPU Card, TDL's Altair/IMSAI compatible Z-80 CPU card was designed to allow the Z-80 microprocessor to run, without modification to the mainframe, in either an Altair 8800 or an IMSAI 8080. At the same time, the design was configured to allow maximum versatility to the user, allowing the full potential of the Z-80 to be available to the user. The ZPU Card is constructed of only the finest materials throughout. All components are first quality prime and obtained from reputable distributors, factories, or their representatives. No surplus material is used anywhere in the design. In order to complement the Z80, which requires only a regulated +5 Volt supply, no components were used which require any other voltage. The total current drain is ,typically 750ma. Separate jacks are provided to accomodate the front panel connectors of both the Altair and the IMSAI, and the ZPU user may at his discretion elect to install either one, or both during assembly.

  • Z80 Micro Emulation
    Zilog Zodiac Simon Goodwin scours the world for Linux-friendly Zilog micro emulators. This month we test a dozen emulators for home computers with Zilog’s Z80 chip at their core, including the very British MGT SAM and Elan Enterprise, Tandy TRS-80 and Exidy Sorcerer, sundry Japanese Sharps, and continental micros like the P2000, Z1013 and KC85/4. The most capable of these previously unreviewed micros are Tandy TRS-80s and MGT SAMs, but others yet unmentioned put Zilog processors to good use. Zilog breakthrough Zilog’s Z80 was the mainstay of home computers in the 1980s, along with the MOS Technology 6502, yet early eight bit computers favoured Motorola 6800 and Intel 8080 chips. Those large, established chip foundries did not foresee the mass market for low-priced micros, so staff left to start small companies to make the 6502 and Z80. Chuck Peddle worked on the 6800 before he set up the 6502 production line, and Federico Faggin founded Zilog, to make the 8080-compatible Z80, after working on Intel’s breakthrough 4004, the first microprocessor. The first three real home computers, aimed at mass-market users rather than hardware hackers, were the Apple 2, Commodore PET and Tandy TRS-80. Soon after Tandy adopted the Z80 that Zilog chip elbowed out 8080s from CP/M business systems and new home computers. Z80s run 8080 programs faster, with many extra instructions, and simpler hardware interfaces. The CPC, MSX, Coleco, Master System, GameBoy and ZX computers were the most famous applications of the eight bit Z80 processor, as we’ve seen.
