- There are now 992 computers in the museum -

Olivetti introduced a mainframe about 1960 which was called ELEA, then in 1965 the Programma 101 - which was probably the world's first real desktop computer. Then a little later they introduced the Audiotronic range of "office computers". The first was the A770, which was replaced by the A7. The A5 was the desktop version. The Olivetti Audit 5 or A5 was largely an electro mechanical computer. It printed via a golf ball typewritter mechanism at the astonishing speed of 16 character per second...
The TA 1600 system was introduced in 1983 at the CeBIT (which was only a part of the "Hannover-Messe" by that time). TA showed a few sample applications and the 1600 family in general. Triumph Adler's hardware included also the 1600/20-3 which was supplied with a permanent-swap-HDD-unit. This unit had a memory/storage capacity of 2 x 8 MB (Winchester technology). Triumph Adler said the system (the 1600) will fit the demand of medium-sized businesses, due to the facts that these companies w...
MIDWICH Microcontroller
Called the Midwich Microcontroller, this British computer was developped to provide a small desktop micro capable of running other equipment throug a variety of interface cards. In 1979 an Italian IC manufacturer designed and began to sell a single board micro system that could be expanded to a full system with a VDU, discs, etc. Called the Nanocomputer, it was manufactured by SGS Ates and one of the distributors in the UK was Midwich. The Nano was somewhat expensive and suffered from a numbe...
RADIONIC Model R1001
This is an extremly rare TRS-80 Model 1 clone, based on an other clone: The Komtek 1 (from Germany). It's equiped with a Level II basic and powered by a Zilog Z80 cpu. _________ Contributors : Incog...
BASF 7100
The BASF 7000 systems are professional computers from Germany. They seem to be based on the Microterm II Intelligent Terminal by Digi-Log Systems, Inc. There were several models in the 7000 serie....
PCC 2000 is a professional computer released in 1978. It was designed in 1978 by Pertec, the company which merged with MITS by the end of 1976. The PCC is conceived as a monobloc machine, where the display and two 8" floppy disk drives are built-in the main case. The mechanical keyboard offers separated numeric and editing keypads. The system is powered by an Intel 8085 microprocessor and offers 64 KB RAM. The whole thing was apparently delivered with an extended Basic language, which has...
TAP 34 is a self design of Terta company from Hungary. Primarily it was designed as a terminal for big computer systems but it was also able to process data alone. The main integrated circuits were assembled in the USSR and in Hungary by Tungsram, but several parts were imported from other countries. The built-in monitor was a DME-28 monochrome CRT made by Orion. This company was famous for its televisions in Hungary and the other KGST countries. The floppy drive attached to the compute...
Based on the MCM 70 / 700 (see this entry for more info), the MCM 800 followed in 1976. It was faster, included 16 KB RAM (instead of 8 KB for the 700), and included the ability to drive an external monitor. Among other things, MCM 800s were used in one of the first french industrial network called Gixinet (along with ARCnet). This was a token-bus type network developped by the Gixi company....
The Imlac PDS-1 is a graphical minicomputer made by Imlac Corporation (founded in 1968) of Needham, Massachusetts. The PDS-1 debuted in 1970 and is considered to be the predecessor of all later graphical minicomputers and modern computer workstations. The PDS-1 had a built-in display list processor and 4096 16-bit words of core RAM. The PDS-1 used a vector display processor for displaying vector graphics as opposed to the raster graphics of modern computer displays. The PDS-1 was often used with...
COMMODORE  C64 Golden Jubilee
Between 1984 (in the U.S.) and 1986 (in Germany), Commodore International celebrated the 1,000,000 machines sold mark in these respective countries by issuing special "Gold" editions of the Commodore C64. These machines were regular C64 models, except they were Golden-colored and fixed on a commemorative plate. The following information comes from Death Adder : Until December 1986, 1,000,000 Commodore 64s were sold in Germany. On this occasion, Commodore Buromaschinen GmbH (...

Microwriter was not really a computer, but a very original pocket word processing system, designed in 1980 by Endfield Cie in the USA and later manufactured in the UK. It used a keyboard with only 6 keys which made it possible to keyboard all the alphabet letters, numerals and punctuation marks. The typing method used the letters shape likeness and only one hand was necessary to type text. It only required a few hours to get used to keyboard and then typing speed could be very fast. The inter...
CASIO  PB-1000
The Casio PB-1000 was an original, well designed and powerful pocket computer for its time. On top of its standard QWERTY keyboard, a row of sensitive keys allowed fast scientific calculations, menus access and text editing. The 4-line LCD display also had 16 sensitive areas. The computer could be programmed either in Basic or Assembly language. The C61 Basic interpreter, based on Japan Industrial Standard BASIC, had a wide range of built-in mathematic, trigonometric and statistic fun...
This computer was an enhanced version of the Challenger IIp. The motherboard was equipped with 3 microprocessors: 6800, 6502A and Z80. An optional 74 MB harddisk was available ($6000 !). It was supplied with a word processor called WP-1 and a database called DMS. An enhanced version of the operating system allowed to connect up to 16 terminals to the computer at one time.

SONY  Hit-Bit 201
The HB-201 was the same machine as the HB-101, but with 64 KB of available RAM memory. It was sold in grey or black case color. The 'P' means 'PAL' RGB video output. Peter de Vroomen adds: The great thing about this computer is that it has a PAUSE button, which physically halts the CPU when pressed. Very handy for debugging or cracking programs :). The PAUSE button is that button above the cursor keys. Also handy is the carryi...
INTEL Intellec Series
The Intellec Microcomputer Development Systems (MDS) were complete computers intended for the development of Intel microcomputer based products. They included a main unit with CPU, RAM, ROM, I/O and interrupt circuitry, as well as all necessary software: Assembler, linker, debugger. Optional EPROM programmer and In-Circuit Emulator (ICE) allowed real-time emulation and diagnostics into user configured system before saving final program into an EPROM. Intellec 4 and ...
The "TRS-80 Pocket Computer" was the first pocket computer Tandy/Radio Shack distributed. Nowadays, it is often referred to as the TRS-80 PC-1, so as to differentiate it from its successor, the TRS-80 PC-2 (and following), which is a clone of the Sharp PC-1500. The TRS-80 Pocket Computer was custom manufactured by Sharp Corporation, and is technically identical with the Sharp PC-1211 (see there for more technical information). There were some minor differences...
ACT Apricot Xen
Codenamed Candyfloss, this computer was aimed to compete with the IBM PC-AT. It was a multipost system capable of controlling up to 16 stations. Three versions were sold: • Xen FD with 512 KB of RAM and 2 x 720 KB 3.5" FDD. • Xen HD with 1 MB of RAM, 720 KB 3.5" or 1.2 MB 5.25" FDD. and 20 MB HDD. • Xen WS (WorkStation) with 1 MB of RAM and no disk drives. Some Xen systems used a large black external power supply unit weighing at least 2-3 kilos, others featured a built-in one. S...
This is a highly IBM PC compatible system. It means that it is truely hardware and sotfware compatible with the IBM PC of that time. Back then, all "PC compatible" systems were not exactly 100% compatible... so it was a real marketing argument for the Olivetti M24. There were two true tests to know if a system was really IBM PC compatible : Lotus 1-2-3 and Microsoft Flight Simulator, and the M-24 was running both with no problem. But in addition to its good compatibility, the Olivetti M24 wa...
Almost no information about this 'computer' which was probably the first microprocessor trainer Texas Instruments produced. The system held two chips, a quad-Nand 74279 logic chip and a 4-bit SPB0400 processor which was the first processor made using the VLSI process technology. One programmed it through various switchs, results were displayed on LED diodes. Thanks to Steve Perry for information and pictures....
Very little is known about this Japanese system. Help welcome !! It apparently had some success in Japan, with great game conversions. Based on the IBM PC architecture, it had excellent sound and graphic features. It has the barebone of a classic IBM PC system but was conceived from the start as a real familial multimedia system. Graphic resolutions go from 360x240 to 640x480 with 256 colors simultaneously on screen from a color palette of 16.7 millions colors. Most of these graphic modes ...

The voltages are +5V and approx +20V - the second voltage isn''t stabilized in power supply and may vary. Didaktik Gama stabilizes it to +12V used for video signal circuitry.
The memory chips are of various origin. I have seen bulgarian CM8164P, russian KR565RU5G (transcribed from cyrilics), or Samsung KM4164B. I wouldn''t be surprised to see czech MHB4164 in some variants.
The 16Kb memory chips are different to the ones used in ZX Spectrum. The chips used in Didaktik Gama need just one voltage, 5V. I have seen Fujitsu MB8118, or Intel D2118.

You can find an emulator for A5105 (and other robotron boxes like the KC85/3) at

I have one I purchased way back then, printer and all. It''s still one of the coolest computers ever made. It was very ahead of it''s time. One of the reason (IMO) that it failed was a lack of IBM PC compatibility. That was the direction everything was going, aside from MAC of course. Another cool computer of the time was the GRID. Good times...

I vaguely remember the "voice" saying something when it booted. I also remember think they were quite old in the late 80s to early 90s, being disappointed that there were so few programs. After a while these mostly collected dust in the backs of classrooms, "computer time" being treated like a reward when we didn''t have much to do. A shame really.

Back in the day, I sold Osborne computers in Falls Church, VA. Recently discovered the original manual v 1.1 (in hardcover folder) multipart registration form, Nov 1981 MicroPro End User Agreement. In case there is historical interest, am offering it up. Any interest? Sold my own Osborne years back and apparently forgot where these documents were.
