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:

2017-04-23 Added PECOM 64 8-bit computer. A small microcomputer developed for teaching computer science in Yugoslavia in 1980s. It is based on CDP1802 processor and has 32kB of RAM. It is relatively slow and has BASIC interpreter in ROM.
The benchmark page has been updated with it.
 
2017-04-16 A new exhibit in portable PC collection: Compaq Contura Aero 4/33C. One of the first ultra-portable PC notebooks, which later evolved in subnotebooks and, much later, netbooks.

In processing: Ei PECOM64, computer used in former Yugoslavia countries to teach computer science in schools. Very strange architecture. Totally not like common Z80, MOS or 8080-based machines.
 

2017-04-02 Acquired another machine - Sintez 2: Soviet/Modovan ZX Spectrum clone which has case looking like ZX Spectrum Plus, but power supply is a bit bigger. It is based on Z80 CPU (foreign) and TTL chips instead of ULA present in original Spectrum. It has also no RF modulator, but a rather high-quality RGB output. It was sold in early 1990s as video games computer.

 

2017-03-12 Acquired a Robotron K8915 computer. It's a CP/M microcomputer with power supply and monitor built-in. Processor is Z80 and this unit has 128kB of RAM. Unfortunately I got no floppy drive or keyboard for it. It was built in East Germany in 1990, so it is quite late unit.
2017-02-25 Added a Z80-based LED display driver: Transled, a newer version from early 1990s.

Well, non-branded PCs at last got their section which is more-or-less done. Although these informations can't be used in PCs with other configurations, you can see them in their page as another exhibits in the museum.

2017-01-31 Acquired and restored Robotron A7100 16-bit PC-like East German computer with proprietary monitor. Unfortunately without keyboard.

BTW: Internet Archive released lots of computer magazines to download or read online. You can browse the collection in its Internet Archive site.
 

2017-01-20 Hello in 2017. There are some new things in still constructed PC section as well as non-branded PC gallery which, when ready, will be also described. Some microcomputers were acquired, yet they need to be repaired and discovered properly.
