AVT ELECTRONICS Comp 2 This is quite a rare computer ! It was conceived by a dutch company called AVT Electronics. AVT is short for Alex van Tienhoven, then the owner of the company. This computer was made in Korea as per AVT's design... This obscure system is Apple II compatible (hardware & software), hence the "Comp2" name. The system is composed of a separate keyboard and a big case housing two 5''1/4 disk-drives, the mainboard and 8 expansion slots.
Tandy Radio Shack 2000 The Tandy 2000 was launched in December 1981, a full year BEFORE the 1000, and proved to be a mistake on the part of Tandy, but to their credit they weren稚 alone, many manufacturers who built systems based on the Intel 80186 CPU suffered the same fate. On the surface the computer was quite the catch: The 典-2000� featured new instructions and new fault tolerance protection over the TRS-80 and COCO lines.
ADD-X Système SMP-5 This is a french professional computer conceived by ADD-X Systèmes based at Blagnac (Toulouse). It was a CP/M and MP/M compatible system, had 64k RAM, two 5''1/4 disk-drives and one 5 MB Winchester hard-drive. It could be expanded to a multipost configuration (up to 3 stations). The following languages were available : Basic, Cobol, Fortran, Pascal, APL.
The Atari 1200 XL was the predecessor of the Atari XL. It had much of the same characteristics, except the size of its ROM KB instead of 24 KB) the BASIC Interpreter being supplied on a cartridge.
Toshiba PASOPIA This is the first home-computer made by Toshiba and was quite powerful for 1981 : 64k RAM, 80 columns, 640 x 200 high resolution and large expansion possibilities. There were two models : the PA7010 with the T-BASIC built-in, and the PA7012 with the OA-BASIC built-in. The advantage of the OA-BASIC is that it can use indexed sequential access methods to handle files, and has an automatic load / run function for launching programs.
Atari 1450 XLD The Atari 1450 XLD has the same characteristics as the Atari 1400 XL. Like the 1400 XL, it has a built-in modem (Bell 103 compatible, 300 baud) and the speech synthesiser chip (SC-02). Contrary to the other Atari, it uses a parallel disk drive controller (a much faster arrangement) instead of the SIO interface. Apparently The 1450 was not released because they were having problems getting the parallel disk drive controller to work properly.
AXEL Click here to read to company history AX-20 This french mono-bloc system had no great success. It was however a nice designed system with its 8 function keys mounted directly onto the monitor (like with some Hewlett-Packard systems). The idea was interesting, because the function of each key was dynamicaly displayed right above it, but it becomes tiring to have to lift an arm to reach these keys... The AXEL-20 can display 640 x 416 pixels with 8 different level of brightness.
WICAT 150 Wicat stands for World Institute for Computer Aided Training. The Wicat is one of the first (perhaps even the first) computer to use a Motorola MC68000 processor. It is a card-based computer. The mainboard just houses the processor, the boot PROMs, a very fast cache memory and the glue electronics. A lot of cards were developed for this computer. Each card has its own CPU: The I/O board called ICI board uses its own 68008 (68000 with 8 bit data bus)...
Alpha Micro 1000 Series The Alpha Micro 1000 was a line of systems based on the 68000 microprocessor. According to customer requests, each system could be configured from a single user microcomputer with 128 KB of RAM, up to a 60-users system with 3 MB of RAM and 2.4 GB of disk storage. The operating system of the 1000 series was AMOS, a multi-user, multi-tasking and timesharing system allowing the user to easily add terminals and printers to the current configuration.
Texas Instruments was one of the first programmable calculators which keeps programs and data in memory, even when it was turned off.
