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.
|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.
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.
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,
will survive longer than previous one and you'll find help in my
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.
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
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.
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.|
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.
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
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.
