Welcome to my old computer collection

Here you will find information about old computers, their parts and peripherals.

The main objective of this site is to provide information not only about technical specifications of old computers, but also instructions to make an old computer running again as well as how to use the old computers (retrocomputing) and its basic software.

You will not find large amount of software for these devices, but some files, needed to make them running, are in this site.

 Site news:

2019-12-08 Added an unknown joystick interface for Spectrum, made by DK'tronics. Probably a "lite" version of their typical dual-joystick interface. As their dual-port interface became "lite" of programmable version of interface, this is probably even more cost-reduced version.
Additional updates to Keyboard repairs and PC information regarding serial ports and RTC in XT.
2019-11-21 Added a Mikrosha (Микроша) microcomputer - a Soviet home/educational computer built arount 8080 processor. It has 32kB of RAM and only a small piece of firmware. Any programming languages like BASIC or even Pascal had to be loaded from tape, fortunately these were relatively small.

Some corrections in Floppy Drives section, related to Polish Mera drives.

2019-10-31 A few updates here and there (mostly Siemens PG685 and floppy drives), updated links, and a new release of ICTester program package.
2019-08-23 Fortunately problems are gone and the website was not absent for more than a few hours. A few updates have been made in Calculators section, as well as in non-branded PC clones adding a 386sx and K6/2, and Hacks.
2019-06-18 WARNING: Technical problems possible: As recently every year, my provider is quite reluctant about renewal, so I have no idea will there be a downtime as last year or not. If so, here's a temporary backup address: oldcompujggniul7․onion - to enter it you may use a Tor program or use a Tor gate, replacing .onion with .onion.ws in the address. As I don't have any other possibility for server (I'm behind five NATs), this is the only workaround I found. This experimental "server" works on a machine with poor network, so just be patient. Yes, only a few kB/s, but it is out there.
2019-06-03 Added Power Macintosh 7220/200 and Macintosh IIfx - one of the fastest Macs in 1990, with 40MHz processor.
Updated Compaq Contura Areo 4/33c page with a broken hinge fix techniques, as I got another unit with this problem.
2019-05-03 Added two interesting Macs: Power Mac G3 All In One, codenamed Artemis, which was released for educational market and Workgroup Server 8150, a PowerPC-based server from 1994. The All In One Mac is a 266MHz PowerPC Macintosh with multimedia capabilities boosted, as well as both floppy, CD and Zip drives in one case with a colour CRT diaplys and speakers. A really interesting machine, a bit older than all-in-one iMacs.
The Workgroup Server is a Power Mac 8100, but without extended graphics capabilities and with server software built-in.
2019-04-15 Added a Macintosh Server G3 - a G3-based Mac in tower casing, based on (and very similar to) Power Macintosh G3 in minitower case.
Also, added Power Macintosh 9600/350 - one of the fastest pre-G3 Macs, with lots of RAM and a fast video board, as well as with second hard disk and ZIP drive.
2019-03-10 Added Macintosh Quadra 800 from 1993 and a year older, but high-end Quadra 950.
2019-02-16 Added an Ericsson 9161 terminal, this was a Swedish mainframe terminal made for bank systems. This is from early 1980s and it's a very powerful machine for its time, with 128kB of memory and Motorola 68000 processor.
2019-02-09 Added Macintosh Quadra 700, a 68040-powered Apple computer from early 1990s targeted towards high-end requirements, one of the first Apple's computers with tower casings. This particular unit was used to control a professional raster printer.

Numerous small updates in 8-bit section. A comparison between Elwirka and Elwro 800 Junior casings, (they are similar, not the same), some small additions in Atari gallery and joysticks.

2019-01-20 Happy New Year.
Added a replica of Galaksija computer I built. It is a small, home/educational computer distributed as DIY kit in 1980s Yugoslavia. It has a BASIC programming language interpreter and 6kB of memory in the best case.

For Macs, there is an Apple Studio Display from 2001, an early Apple's LCD.
