 NETRONICS Elf II
The Netronics ELF II was an early microcomputer trainer kit featuring the RCA 1802 microprocessor, 256 bytes of RAM, DMA-based bitmap graphics, hexadecimal keypad, two digit hexadecimal LED display, a single "Q" LED, and 5 expansion slots. The system was developed and sold by Netronics Research and Development Limited in New Milford, CT, USA.
Unlike similar "bare circuit card" trainer/experimenter computers of the day, the ELF II could be easily expanded thanks to its built-in bus.

 ECD CORPORATION Micromind
The Micromind was a very innovative machine ahead of its time ! But despite the small group working on the machine, prototyping and developing, and pushing the limits of the time, the machine never shipped. Apparently only a few prototypes were produced.
Development began as early 1975/1976 but commercial adverts appeared only in 1977.
One of the main features of the Micromind was its innovative (for the time) redefinable characters. Up to 120 characters could be software redefined by the ...

 GESPAC Gescomp 720 / 730
GESPAC SA was a Swiss company who designed the G-64/96 Bus in 1979.
This interface bus concept provides a simple way to interface microprocessor modules with memory and peripheral modules on a parallel bus. The G-64/96 Bus uses a simple, yet modern and powerful interface scheme which allows a higher level of functionality from the single height Eurocard form factor. The low overhead of the G-64/96 Bus interface greatly eases the design of custom boards by the User. This is why, even many year...

 WELECT W86
The W86 is a french computer released in 1983 by Welect. It's the second computer released by Welect after the W80.2.
The W86 is powered by an Intel 8086 (hence its name) to catch up with the IBM PC compatible trend of the moment and is thus able to run MS-DOS. But the W86 is also equipped with a Z80A to also be CP/M 86 compatible. It's thus an hybrid machine typical of the mid-80s when the professional industry was moving from CP/M to MS-DOS.
There are 128...

 UNITRON (BRAZIL) Mac 512
This machine was the first Macintosh clone in the whole world.
In Brazil it is almost unknown and there are people who doubt its existence, but it really did exist!
This computer almost started a commercial war between Brazil and the United States. Apple persuaded the U.S. government to use everything it could against the Brazilian clone makers (increases in import taxes for brazilian products such as orange juice, shoes, etc.) until this machine was no longer made.
Brazil had a tr...

 EPSON QX 10
The QX-10 was a robust small business computer that used tried and tested technology rather than anything too innovative. Nevertheless, it was designed to be complete in itself for both hardware and software.
It had an enhanced keyboard with 10 function keys and up to 16 fonts can be defined. It had a battery to save clock, date and a small 2048 characters buffer. It could use MS-DOS programs thanks to an optional 8088 card.
Byte magazine said in January 1983:

 RADIOLA VG 5000
Radiola and Schneider became Philips subsidiaries in 1990 when Philips bought the French Schneider TV assembly plant located in Le Mans - the West of France - and then named Radiotechnique (RTC).
The Radiola, Schneider and Philips VG-5000 were exactly same machines, apart from the case colour. They were conceived and manufactured in the RTC Le Mans factory and only intended for the French market.
At the time, RTC also made the "Minitel", a phone video term...

 SINCLAIR ZX SPECTRUM
The Sinclair ZX Spectrum was one of the most popular European computers of the 80's. Two models were launched: one with 16 kb RAM and one with 48 kb RAM.
One of its most "interesting" characteristics is its keyboard! Some keys have more than five (!) functions! It is impossible to type BASIC keywords letter by letter, instead you have to use function keys. A lot of peripherals and programs were developed for this computer. It seems that several models of this computers were launched (at least...

 IBM Instruments Computer System
About this strange computer, IBM said that it was "A unique combination of features and a new dimension in small computers".
The 9000 (its reference name) was first presented in June 1982 at the COMDEX show in Atlantic City. The system ans peripherals was manufactured by IBM's instrumentation division in Danbury, Connecticut.
It was first and foremost intended to be used by scientists and engineers for instruments control and data acquisition. Its modular concept made the system to g...

 IBM 5100
In September 1975, IBM announced its smallest and first portable computer (If you consider a 28 Kgs. computer portable, that is), the IBM 5100, no bigger than one of IBM's typewriters.
Developed in Rochester, it used the same operating system as IBM's /370 line of main frames. Thus it could accommodate the same APL interpreter, permitting the use of APL programs. A BASIC interpreter was also available, depending of the 5100 version chosen.
This was the first widely marketed and supported p...

 CCE MC 1000
What a weird computer !! Though it has a lot of similarities with other computers of that time, it seems to be however an original Brazilian production, a kind of mix between several popular systems.
Its name MC-1000 is strangely close to MC-10 from Tandy. It uses the same video-controller (Motorola MC-6847) but Sound chipset (GI AY-3-8910) and CPU (Z80A) are different. The character set is almost identical, but keyboard layout and Basic statements are not the...

 SHARP PC-1210 / 1211 / 1212
The Sharp PC-121x series is generally regarded as the first commercially available pocket computers ever. Its design was based on the way normal pocket calculators were built, but the case was turned 90 degrees to allow for a wider display, and most mathematical function keys were replaced with alphanumerical keys. Its main intended use was BASIC programming, although it could be used as a calculator as well, by simply typing in the math functions with the alphanumerical keyboard in one line of ...

 ISOT EC-1035
Very little information about this Bulgarian mainframe used by big East European companies as an industrial or information management system.
It was partially compatible with IBM mainframe and could also share programs and data with the russian Minsk-32. It could run in multiprogram mode thanks to its virtual memory.
The ISOT brand name means 'State Economic Alliance'
Thanks to Bojidar Stefanov for information and picture....

IMSAI VDP 80
I had one of these 2nd hand and it was solid as a rock. The PerSci 277 drives were much faster than 5-1/4" floppies and the MPU-B board functioned well. Came with WordStar, CBASIC and PL/1. ALL Documentation also. Did have to recalibrate the PDS eventually.

TANDY RADIO SHACK 1000 SL & SL/2
I have my Tandy from long ago. It’s a 1000SL/2. It’s doing well, but very noisy. So I’m going to have to oil the fan at some point.

ELECTRONICA CIP-03
A rather important (but as far as I''m aware, entirely obscure*) feature of the CIP03 was that it still contained a full 64K or RAM, besides the 16K ROM. Clearly, given the 64K address space, only 48K of that RAM remained accessible at runtime - but what most people didn''t seem to realize is that the low 16 of RAM remained accessible FOR WRITING during normal operation, with a D-latch at $I can''t remember which I/O address$ accessible to FLIP that, leaving now the ROM getting accessed for writing (LOL) and the RAM FOR READING, instead of the EPROM. So basically all you had to do was "copy the first 16K onto itself" first, changing whatever you didn''t like about the original BASIC, then flip the latch and bingo you were running your "improved OS".
Which worked wonders for me in fixing the notoriously broken Spectrum NMI vector - now I could run my code any time at the click of a button in a way that was impossible to interfere with in software: basically, a "cheat POKE" user''s wet dream. It was bloody GLORIOUS. Later at some point the same trick worked like magic to transfer code from a CIP03 to an emulator on a PC via a custom, jury-rigged expansion port -$ LPT1 connection: at any point you wished, you pressed the button hooked up to the NMI pin, the CIP froze in place (running my pre-loaded glue code) and transferred the full contents of the upper 48K to a companion Pascal program running on the PC that wrote it into an emulator file$ then you just loaded that file into an emulator, and watched your game un-freeze from the exact spot you stopped it at.
* upon discovery of this "feature", I obviously tried to inquire about it at the local Electronica service. The "WTF"-slash-"huh?" attitude of the staff was utterly priceless.

SANDS 3000
It connects to your TV antenna socket to play 1 of 4 different pong games: tennis, hockey, squash (1 player) and squash (2 players). The player slider control are detachable from the main console. The console runs on 6 C-size batteries, or from a 9V external power supply (not included). I don''t have the UHF cable, but I think it''s just a standard TV aerial cable.
