  • 2016
28.11.2016 Acquired Polish Creator IKT-5A serial port terminal made ca. 1993. It was probably manufactured before IKT-6, and still has Fura Elektronik logo in software, while being sold by company called "Creator". It is in "new old stock" condition, in a box, probably not used at all.
16.10.2016 New terminal in collection: Siemens Multitel Fe Ap 90-1.1. It is similar to earlier Siemens Bitel machine, but is simplified and upgraded. It is also in completely working condition and has a key for its lock. These terminals were used solely for German Bildschirmtext service, used to transmit information pages by telephone line.

Also, Elwro Desktop calculators list has been updated.
 

28.09.2016 A new portable laptop PC in collection: A V30-powered Nec Multispeed HD from ca. 1989. It has 640kB of RAM in static chips, 20MB hard disk and 720kB, 3.5" floppy disk drive. In its ROM there are useful programs to minimize power-consuming hard disk usage. These programs can work in a RAM disk saving more power. And if user wants to work with external monitor, it is possible to detach the screen and use the base like keyboard.

Still slowly building up the PC Section.

04.08.2016 Added a Philips VG8000 MSX computer. Quite early MSX machine with 16kB of RAM and without many possibilities of expansion, popular in MSX computers.

The website finally got rid of most JS code, substituted with CSS. Although there was almost no JS code here, it was still in my opinion overused. Visitors' CPUs have many other things to do.

29.07.2016 Because I was diagnosing some hinge problems with my Pocket-PC palmtop, I've added two photos of the mainboard of my HP 200LX. You can see them in the gallery. Mainboard is quite early unit without RAM expansion connector and with some hand-written markings on chips.
 
25.07.2016 Added a comparative benchmark of 8-bit computers. Now it can be seen which one is the fastest and which one has some performance drawbacks. Benchmark covers some simple calculations as well as displaying large amounts of text on screen.
 
18.07.2016 Hello from the new location. Free hosting decided to roll up and leave their customers without any support nor access to servers, probably because of DDoS attacks. Current website is a bit modified, so all parts of previous old site have been incoroprated into newer (yet still old-looking) one. Be careful of falling URLs as some parts are still under restoration. I hope this new address, http://oldcomputer.info, will survive longer than previous one and you'll find help in my site.
 
08.05.2016 Added Amstrad PcW9512 computer, enhanced version of PcW8256. This is a Z80-based CP/M machine with 720kB 3" floppy disk drive and 512kB of RAM. It has a monochrome, white built-in CRT display and can use a proprietary daisy wheel printer.

And don't forget to look at the refreshed Restoration and discovery of old computers text.
 

22.04.2016 Added Siemens PG-685 portable computer with 286 processor, being more CP/M machine than a PC but it can run MS-DOS 2.11. It was used to program industrial control machines. There is 1MB of RAM and 20MB Winchester-type hard disk. Picture is generated on internal monochrome CRT monitor.
Running with such antique form, this computer is not so old, it is from late 1980s. It is made of surface-mounted chips and has quite modern technologies under the hood.
 
13.04.2016 Added a RFT LC-R tape recorder made especially for East German RFT KC85 or KC87 computers. However, it may work with any computer using sound input/output.

 

04.04.2016 Added an unusual Z80-based computer from mid-1980s: Alcatel 7100. It is built on a base of AES 7100 Model 203 word processing computer, but has quite unusual modifications introduced probably by Alcatel. And it seems that there is no operating system nor software for it.
12.03.2016 Added Polish IKT-6 terminal, late-1990s unit which works with PC peripherals.
Probably non-original power supply unit for Unitra portable calculators.
Small update in slide rules section - two items added.
25.02.2016 Added few new things.
 - Acorn BBC Master Compact computer, which is a smaller version of BBC Master, a disk-based computer from 1986, this one with 3.5" disk drive.
 - Commodore 1084S-D2 monitor for Amiga 500, a bit different than earlier D1 version,
 - Two photos of Amiga RAM expansion and mouse.
20.02.2016 A small update with RFT KC85/4. New photos and loading programs procedure corrected a bit.
Added floppy disk drive and controller for RFT KC85/4. Well, it is in fact another computer with own Z80 CPU and RAM, which runs a CP/M clone. The original KC85 becomes a terminal then.
 
15.02.2016 Added text: Restoration and discovery of old computers. Explaination what to do with old computer to restore it and discover its capabilities. In queue: More Robotron KC85/4 photos, Robotron KC floppy disk drive and controller, maybe few things more.
 
06.02.2016 Acquired a small, portable, battery-powered 8-bit microcomputer with docking station - Ronex TPC-8300. It can be programmed using BASIC and results are shown on LCD screen or printed using unusual pen-based printer working more like a plotter.

Hosting has small problems with image gallery, I think they will fix it soon.

16.01.2016 Happy new year. Another 8-bit microcomputer in collection: Texas Instruments TI-99/4A, an early home computer with 16-bit processor and unusual RAM access methods.
Slowly updating PC section with interesting computers.
  • 2015
     
19.09.2015 Added Humantechnik Textel Compact "digital teletype" terminal - device with built-in modem and telephone handset coupler, manufactured in small quantities in early 1990s. In fact it is a battery-powered, portable microcomputer system built around 6502 CPU with system programmed as teletype, with memory, printing support and address book.
15.08.2015 New strange Apple keyboard in collection
Finally added 3Com Palm V to lists and descriptions. Well, finally powered it up. Holding power cables with one hand, palmtop with second, taking photos with camera mount...
 
25.07.2015 Two new terminals: Siemens Bitel T3210 and Magis Club. Siemens for German Bildschirmtext service, Magis for French Minitel.
Siemens is a full microprocessor system from 1986. It consists of few PCBs of different functions. Magis (1999) is newer and it is built around embedded systems microcontroller.
 
9.05.2015 I've analysed signals coming from Transled LED display driver. All results and explaination how to do it can be found in my article. There is also a Perl script which converts logic analyzer data to LED display "images".
 
01.05.2015 A new computer in collection: Acorn BBC Micro Model B. This famous British computer was used in many schools in the UK. 6502 processor, ca. 2MHz, 32kB RAM, built-in BASIC and ROM expansion. My unit has additional expansion connector for Solidisk board, but no board fitted.

PC Section is under construction.

18.02.2015 New in collection: Amstrad PCW8256 - an English word processing CP/M machine. It was simple, efficient and cheap so it gained popularity as office computer and word processor.
Also some updates to Unipolbrit Komputer 2086.
 
 
29.01.2015 Welcome in 2015. Today more updates. Added 3 new computers: Timex-Sinclair TS1000 (ZX81 clone for USA market) with printer (non-standard spark-printing mechanism which can print only on special paper) and 16kB memory expansion, Robotron KC87 (also known as KC85/1) and KC85/4 - KC85/3 with improved architecture and more mmeory.
  • 2014

22.12.2014 Others section complete.
 
 
13.12.2014 Added new media: Minidisc (unfortunately, no device to read it), 8-bit accessory: Amiga joystick tester. Big thanks to donator :). A new photo in Small QIC streamer page, slowly completing Others section.
Sharp MZ-800 - I've got another one with tape recorder, look for update.
06.11.2014 A new computer in collection: Robotron A5105, sometimes called BIC, a Z80-powered computer which could run Basic programs as well as CP/M software. This computer has been manufactured in East Germany in 1989.

 

14.10.2014 A new laptop in collection: Compaq LTE 5300. Nice Pentium-era notebook computer with Windows 95 and one of the last in Compaq's traditional LTE series (started from 286).
Additionally Atari SM124 monitor and part of IBM terminal (unfortunately only display unit and keyboard - without logic part): IBM 3180.
20.09.2014 Welcome back. The web server had problem and site was offline for about 2 weeks. Not many changes, you can see Tandy 1100FD laptop and new Atari computers: 520ST and 800XE. Tape recorders and Joysticks sections have been updated with new accessories (additional manuals/photos of Atari tape recorders and QS130f joystick).
 
28.06.2014 Now Laptops and portables section is probably complete. It shows all my notebooks and portables to ~2000 with few exceptions (some unusual newer machines).

My Philips Videopac G7000 is running now as I replaced bad CPU with Intel 8748 flashed with microcode.
 

26.05.2014 Added Microtrol rare portable computer.

10.09.2013 There was no update for a time... I came across an old PC manufactured by IBM. Restored it, this PS/2 is mostly compatible with ordinary PC, only HDD connector is non-standard, FDD has power wires in ribbon cable. I had to modify Dallas 1287 RTC to make it work as its battery was dead. You can see its photos.
10.06.2013 Now you can see this small Alcatel terminal: Terminatel 258. Designed for French Minitel telephone network, this unit was used to connect to remote systems directly through telephone line. This version has Polish keyboard, menu, character set and messages and starts to phone book with optional password protection.
04.06.2013 Commodore 128D, DCR in fact, arrived. I don't have keyboard for it, but it boots and starts properly to C64 and 128 mode and can be tested with cartridges. You can see it in its page. I'm also slowly doing a DIY keyboard for it.
I'm awaiting an Alcatel terminal, I don't have any information about it, after I discover something i'll post its page here too.
20.04.2013 Another item in my collection: Schneider Euro PC II. Restored from leaking battery problems, now working, you can see its photos.
Ah, power connector is 19V DC (may be unregulated), looking to the holes of connector: two on the left to +, two on the right to -. There's an article how to modify PC floppy drive to Euro PC.
 
12.04.2013 Media section is ready. About floppy disks, streamer tapes and other data storage units.
 
01.02.2013 Identified Hilger as LSI Octopus computer. Don't forget to look at some photos of Robotron manufacturing plant in Sommerda!

Removed probably all JS code, now pages are few kB larger but it's possible to use it in very old browsers. Only HTML and CSS. It should be possible to open all links in new tabs now too.
 

18.01.2013 Finally got Robotron 1715 working. Written more information, tried to describe mainboard, you can also see photos of running software.

 

02.01.2013 Happy new year!
