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 ...
SEMI-TECH (STM) PC
This extremely rare computer is Portable PC (IBM compatible) conceived in the same plastic case as the Pied Piper, released by the same company in 1983. This computer incorporates a lot of features in a compact case, which was quite innovative at the time: built-in LCD display, printer, modem, phone and disk drives ! The STM PC is based on an Intel 80186 processor and two quadruple-density disk drives. The processor is faster than the one used in the IBM PC, a...

The unit, which also houses the controller, may have memory ranging from 64K to 256K and capacity for up to 20 terminals. Up to 20 Tina or David computers can link to Goliath as a distributed data processing system. For ...
LOGICAL MACHINE CORPORATION (LOMAC) Adam
The Adam was the first computer released by Logical Machine Corporation (LOMAC) in 1975. In 1978 they also produced Tina which stands for "TINy Adam". In 1983 Logical released the David, and the L-XT in 1983. There was also the Goliath, a data storage server with 5MB hard drive. Goliath could be connected to up to 20 Davids or Tinas. David and Goliath names makes a clear reference to the mythic...
LOGICAL MACHINE CORPORATION (LOMAC) Tina
The Adam was the first computer released by Logical Machine Corporation (LOMAC) in 1976. In 1978 they produced Tina which stands for "TINy Adam". It seems to have the same specs as David but with two 8'' floppy disk drives. There was also the Goliath, a data storage server with 5MB hard drive. Goliath could be connected to up to 20 Davids or Tinas. David and Goliath names makes a clear reference to the mythical story found in the biblical Book of S...
LOGICAL MACHINE CORPORATION (LOMAC) L-XT
The L-XT was the last computer released by Logical Business Machines, after the Adam, the David, the Tina and the Goliath in 1982. It was announced at the 1983 COMDEX Fall in Las Vegas, and commercially available in March 1984. The L-XT uses a 16-bit Intel 8088 CPU with 192KB RAM, and equipped with a 5.25'' floppy drive unit (320 KB capacity) and a 10 MB hard disk (upgradable to 60 MB)...
LOGICAL MACHINE CORPORATION (LOMAC) David
The David is not the first computer released by Logical Business Machines. In 1974, LOMAC (Logical Machine Corporation) released the Adam. Some times later they also produced Tina (for TINy Adam). There was also the Goliath, a data storage server with 5MB hard drive. Goliath could be connected to up to 20 Davids or Tinas. David and Goliath names makes a clear reference to the mythical story found in the biblical Book of Samuel. The David is powered by a 16-bit Intel 8086 CPU w...
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 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 is 128 KB...
SMOKE SIGNAL CHIEFTAIN COMPUTERS The Chieftain 9822
In 1978, Smoke Signal Chieftain Computers (SSCC) released their first computer: The Chieftain, followed in 1980 by the Chieftain Business System, an update to the original Chieftain. At the start of 1982, the company introduced the Chieftain 9822, an update to the Business System featuring the same processor and static RAM options, as well as the same nine-slot bus equipped with the first two Chieftains. The system could be equipped with either two 8-inch or two 5.25-inch floppy drives and...

DRAGON DATA LTD  Dragon 64
The Dragon 64, launched in 83, was exactly the same computer as the Dragon 32, except that it had 64k RAM instead of 32k, an OS9 operating system and a RS232C connector. The Extended Basic has been modified to provide RS232 I/O calls, to remove the USR bug present in the Dragon 32 ROM and to add calls allowing the additional interpreter to be invoked. This second interpreter was the same Extended Basic re-compiled to run from a higher memory address and store...
LAMBDA ELECTRONICS LTD PC 8300
The Lambda 8300 is basically a ZX-81 clone. Made in Hong-Kong (by Lambda Electronics LTD? DEF?), it was designed as a cheap computer for initiation and was licenced to many companies throughout the world. This explains why the same computer can be found under many different brands and names (DEF 3000, Power 3000, Basic 2000, Basic 3000, PC 2000, PC 8300, Marathon 32K, IQ 8300, Futura 8300, Your Computer, etc.). But on all mainboards is written a generic "PC 8300"...
TOSHIBA  T 1200
This page is dedicated to Toshiba range of PC compatible laptop computers. The T1200 is first described model. More models will come soon (see 'Read more' section). T0SHIBA T-1200 The Toshiba T1200 was a very advanced laptop for it’s time, being able to run many powerful programs only a proper PC could use at the time. It has an 8 Inch screen that can only use scales of Green and Blue. Another Feature was the first “Resume” Feature, kind of like suspend or Standby on today’s comp...
ALTOS COMPUTER SYSTEMS ACS-586 / 686
The ACS-586 was a multipost system which could handle 5 users or more (8) with optional cards. To connect the terminals, there were several RS232 ports at the back of the system, labeled JA, JB, JC, JD, JE, etc... The ports not used by the terminals could be used to connect any serial peripheral, i.e. modem or printer. The 186 was the first computer from a big company to use Xenix as its native operating system. Xenix was the Microsoft "adaptation" of Unix. This system was quite well desi...
YENO SC 3000 / SC 3000H
The Yeno SC-3000 is the same computer as the Sega SC-3000. It was only rebadged YENO and sold in some european countries through a deal with Sega. Same with second version SC-3000 H (pictured here) which only improvement is its mechanical keyboard. See the Sega SC-3000 entry for more info......
MAGICLICK Teleclick
This is an obscure Argentinian pong powered by a General Instrument AY-3-8500-7 chipset. Though it looks like a classic pong system, it is interesting for at least two reasons. First, the paddles are built with calculator or remote control plastic cases !! Indeed, once opened, you can clearly see the holes planned for the plastic keys (see "more pictures" section)... The second unsual fact is that, thanks to the GI AY-3-8500-7 chipset, the system offers a game rarely found on most pongs : ...
POLYMAX Maxxi
The Maxxi was one of the first Brazilian clones of the Apple II and Apple II+. It was manufactured in 1982 by Polymax, a subsidiary of Abicomp, which headquarters were located in Porto Alegre. Polymax also manufactured larger computers for commercial applications. It has a slightly different design than other Apple-compatibles, with a taller case that supposedly facilitated internal ventilation. Due to the success of Apple in the North American market, sev...
HEATHKIT / ZENITH  Z-100/110/120
The Z-100 series professional systems were bi-processor computers. They used an 8-bit Intel 8085 to keep the CP/M compatibility and thus run a wide range of professional software, and a 16-bit Intel 8088 to run MS-DOS or IBM PC/DOS OS's Two models were released: the Z-110 (pictured) which could display color graphics and was delivered with monochrome or colour monitor, and the Z-120 which had a built-in monochrome (green, amber or white) monitor. Z-Basic was the only language...
TANDY RADIO SHACK  TRS 80 PC-2
After the success of the TRS-80 Pocket Computer (a.k.a. TRS-80 PC-1), Sharp also manufactured their PC-1500 (see there for more technical information) in a version for Tandy Radio Shack. This machine was marketed as the TRS-80 PC-2 (catalog number 26-3601). Internally, it was exactly the same machine. Only the front face design had been changed: the keyboard layout was different, with an additional enter key, and the dis...
ATARI  520 / 1040 STf / STfm
The Atari 520 and 1040 STf were the direct successors of the Atari 260 ST and Atari 520 ST. In fact, they had the same technical characteristics except from built-in floppy drive (hence the f of STf). The 3.5" floppy disk drive has been integrated with the power supply into the computer. The early first versions of the Atari 520 STf had a RAM based Operating System (they have a 32 KB ROM), this ROM will be quiclky replaced by a 192 KB ROM which holds all...

IBM  PS/1
I just restored an IBM PS1 2133 back into operating condition. It had a failed 129MB Maxtor hard drive. I tried to install an Apacer 128 MB solid state drive but the BIOS would only recognize it as a 27MB drive and it was not recognized as a valid drive by DOS to perform FDISK on it. So I removed a 245MB Seagate hard disk from another old 486 computer that still works and the BIOS recognizes this and the computer boots and works perfectly. If anyone has any advice on where I could find solid state drives in the 128MB range that would work with old DOS 386 and 486 machines, it is appreciated. The Apacer SSD was recognized by my Toshiba Portege running Win95 as an advanced IDE drive so that may be the problem of the older BIOS''s not recognizing the drive properly.

NEC  PC 8801
The NEC PC-8801 was released in North America. It was called the NEC PC-8801A. I should know, I own one. I will eventually upload a video of it on YouTube, just the hardware I will need to eventually get the correct monitor before I could even think about the software. I have the 8" drives. I''m not sure if the 5 1/4" drives were released in North America.

Q1 CORPORATION Q1 System
I had one of these interesting systems, which I believe came from the National Enterprise Board (NEB) in the UK. Mine was a Q1 Microlite (manufactured between 1978 and 1980), with an 80 character x 8 character high quality, sharp orange gas plasma display. The Q1 range had excellent keyboards and distinctive orange gas plasma screens, housed in futuristic black and orange boxes. The branding extended to the file servers and printers. They were examples of pioneering industrial design, and quality workmanship. One strange quirk was that the workstation was very polite, displaying the message "Welcome to the Q1 microlite", and "Q1/Microlite at your service". Some thought and care had gone into the design and presentation of this quality computer. I was very fortunate to have a high specification file server, with a 10 Mb (7.29 mb formatted) four platter 8" hard drive, and a matching 2 Mb (1.2 mb formatted) 8 inch floppy drive. I was amused to find that the file server was fronted by two large red and green neon lights, like something from a 1960''s science fiction series. It took approximately 20-30 seconds to boot, and when the hard disc had reached the operating speed of 3,600 RPM, the green light illuminated, indicating it was online, and ready to boot the Q1 workstation. I taught myself to reset the workstation or start a cold boot after the file server had fully booted up from cold, after a few false starts. My model came with a rebranded NEC spinwriter printer, which is similar to a daisywheel but with an unusual thimble printing mechanism. Print quality was outstanding. Being a high end business computer, build quality was breathtaking compared to the 8 bit machines I used in the 1980s. I am not surprised that NASA used these computers and they were exported across the UK, Europe and the Middle East. When booting off the hard drive and communicating over the high speed (300 kb) 10-Base 2 coax network, it was a respectably fast machine. The Q1 had a distinctive boot sequence : it would boot from the floppy (if present), then off the hard drive, so it was advisable to remove the floppy disc before booting the file server. The 32K memory seemed to be the main limitation when editing large files in the EDIT editor. The Q1 appeared to page text in and out of memory, which was fine on the hard drive but less satisfactory on the 8 inch drive. I was impressed by the PL/1 compiler, a port from IBM System/360 mainframes. There was also a COBOL compiler. It must have been a huge challenge to fit these complex language compilers into a Z80 machine with a mere 32K of RAM. Finally, the quality of documentation was excellent, and they were quite speedy when connected to a dedicated Q1 file server (10 mb hard drive and 8 inch 1.2 mb floppy). I had to fashion up my own coaxial cable and solder in a T-piece terminator, but to my surprise it worked and booted up.

KENBAK COMPUTER COMPANY Kenbak-1
Julian Skidmore has some great comments about speed, but I have a few corrections. While the nominal clock speed is 1 MHz as stated, and there is a divider which divides it down to two 500 KHz clock phases signals for the shift registers, these Intel 1404A shift registers are actually two lines multiplexed, so each of the clock phases cause one input and output data, so the bit rate still stays at 1 million bits per second. But she''s off by a factor of 3 on the instruction rate. And while Mike Corregan has some great analysis, and did some python emulations, you can''t beat measuring the instruction time on a real original Kenbak-1 computer. On my computer, which has a clock rate a bit low (800 KHz, maybe due to aging of resistors and capacitors) the standard "count and display" program executes at 768 instructions/second, and those are all 2-byte instructions. If my clock rate was increased to the nominal 1 MHz, I''d expect the instruction rate to be close to 1000 instructions//second. The program on the website kenbak.com when run, flashes the high-order bit at once/second, which is 256 loops, and 3 instructions/loop, so 768 instructions/second.)
