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.
Power Macintosh G3
Blue&White. This makes a complete casing series with
Power Mac G4,
G4 MDD and
G5. Apple released a
re-designed PowerPC-based Power Macintosh line since 1999 to the
end of PowerPC series around 2007. Also, a Power Macintosh G4
Cube has been shown as
even more stylish part of the series.
|2017-10-21||Added a Power Macintosh G4 Quicksilver, an early 733MHz unit, unfortunately not functional. It has 256MB of RAM and hard disk, as well as re-designed case (contrary to blue Power Mac). Also added last G5 Macs, Power Mac G5 and early iMac G5. G5 Macs were the last models with PowerPC processors, after making them quad-core and overclocking enough to add liquid cooling to the last Power Mac G5, Apple decided to switch to Intel processors - Macs became a nicely-engineered PCs and Mac OS X became ported to Intel architecture, allowing PC users to make "Hackintosh" PCs running Mac operating system..|
|2017-10-13||Added two terminals: Loewe Multitel D for German Bildschirmtext service, with telephone support and monochrome screen. The second terminal is ITT Courier, with colour display, which was used with IBM mainframe networks. It is an unit from 1986, having 64kB of memory and color display driver.|
microcomputer. This is a Z80-based home computer with 4kB of RAM
and BASIC, designed more to play games and learn BASIC than to
do serious programming. It was sold under Mattel brand, but made
by British Radofin company. 4 months after release it was pulled
from the market.
Ah, finally found keyboard for ALR Proveisa server, it can be seen in gallery.
|2017-08-05||Added quite modern Mac (2005) - Apple Mac mini. A PowerPC computer enclosed in compact case sold as low-end Macintosh to make PC users swap to Mac easier. As its form is compact, most of these computers were used as set-top boxes and media players.|
|2017-07-29||Added iMac G4 700MHz, flat panel
version. It was the first iMac model with flat panel display,
beginning of abandoning CRT displays. Picture quality was quite
good with 15-inch TFT making iMac still a nice computer for
graphics processing. As with all iMacs, its case is in quite
Added strange 1980s controller machine: Shimadzu C-R4A, probably from some scientific instrument.
Philips Minitel 2
terminal, a small CRT terminal which was used to access French
Minitel communications network. As they've been built to quite
strict standards, it's very similar in construction to e.g.
Awaiting a new-old Mac, one of the first with LCD.
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
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,
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
|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
|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.
