Vector Graphics  MZ  	    The Vector Graphic MZ featured the same hardware basis as the VIP model: S-100 based system with a Z80A processor running CP/M operating system.  However, its separate main unit had an 18 slot motherboard and integral dual floppy disc drives (2 x 315 KB).    The system came with 48 KB of RAM, 4 KB monitor ROM, and used the Vector 3 "Mindless Terminal". Although it may look like a terminal, the Mindless Terminal only had a parallel keyboard, and a B/W monitor.

TANGERINE  MICROTAN 65  	    This computer is what is the ZX-80 to the ZX-Spectrum, but for the Oric 1. Tangerine developped this computer before they became Oric and produced the Oric-1.  It was mainly sold in kit, without the complete keyboard shown in the photo, but with a little hexadecimal keyboard.    The unextended Microtan 65 couldn't use Basic (Basic65) due to its RAM limitation (1kb), so only machine-code was usable.

Tandy Radio Shack  TRS 80 MODEL II  	    The TRS-80 model II, is the obscure brother of the TRS-80 family. Many internet pages deal with the models 1,3 and 4 but omit the model 2... This is maybe because the TRS-80 Model 2 was intended to be a business computer for use in offices and labs. Thus it is equiped with a full height Shugart 8'' drive with a capacity of 500k which is a lot compared to the 87k offered by the TRS-80 Model 1 system disk.

South West Technical Products Corporation  S/09  	    The SWTPC S/09 system was the second computer of the brand based on the Motorola 6809 microprocessor, said to be the most powerful 8-bits general purpose MPU available.    As with the first 6809 version, it used the SS-50 version bus. The S/O9 system had a 20-bit adress bus. It was able to address up to 768 Kb. of memory and used dynamic address translation to map 4K pages into the 64K address space of the microprocessor.

Sord  M223 series  	    These computers were generally sold for specific professionnal use along with the appropriate software.    Two models were launched: the Sord MK II 203 and Sord MK II 223. The difference is that the 223 has 3 x S100 slots for easy expansion. Both have a special DMA channel for the disks (floppy and hard disk).    Some software was sold with them, which included the MFDOS, several Sord BASIC's, a compiled Basic (C-Basic) and many tools.

SOLID STATE TECHNOLOGY  Athena  	    Little is known about this obscure professional computer.    The Athena used a true multi-tasking OS that enabled single keystroke application switching. It also incorporated intelligent distributed multiprocessing into perpherial interfaces.    The machine and OS were developed by an MIT graduate and conceived by Solid State Technology from Boston. The Athena is based on a 8085 Intel chipset.

Sharp  MZ 80K  	    The MZ-80K was, alongside the Apple II, the Commodore PET and the Tandy TRS 80痴 one of the best known computer in the early 80's. Its name stands for "M" from MICRO and Z-80 from the computer it uses.    It has no language in ROM, and BASIC has to be loaded from tape. Sharp called this "clean design", as you could choose what you wanted to put in your computer, the MZ-80K being delivered clean...

Sharp  MZ 80C  	    The MZ-80c is based on the MZ-80K, but offers some enhancements to match the professional market of that time. The price was improved too ;-) It was the first MZ-80 computer to be delivered assembled as opposed to first MZ-80k which were sold as kits.    The RAM size is now of 48 KB. The keyboard which was so strange on the MZ-80K because of its matrix organisation, has now a more common layout with a large spacebar key. The numeric keypad is separated.

Seattle Computer  Gazelle  	    Even if you've never heard of this massive computer, the Gazelle is truly a historic computer. Neither because it was one of the first 8088, then 8086 based computer, nor because this Gazelle is propably the heaviest 8088 system ever built, but because it was the computer Tim Paterson wrote DOS for, the first DOS operating system that became later MS-DOS 1.0 when Microsoft bought the rights to DOS from Tim's company, afterwards.

BS  SBS 8000  	    The SBS 8000 is an early japanese system. The most remarkable feature of the SBS 8000 is its originaly shaped case. It looks like the keyboard had been placed in an area cut with a knife.    There are in fact two models of the SBS 8000. The basic model has only 16k or 32k RAM and a Basic language built-in (Super-Basic). The 12" monochrome monitor sold with it, could display 16 x 64 characters.
