||Acquired another BTX terminal:
manufactured by Siemens, this terminal with built-in CRT monitor
was used to connect with BTX network. It is made using much
newer technology than (even later) Loewe units. It has markings
with logos and was distributed by German Post Authority for
accessing the network.
Got some old Macs.

Terminal keyboard. This is a serial terminal in form of keyboard
for a more complex digital trading system. It has a small LCD
display built-in and some useful tools such as calculator and
PC Section finally looks more or less
complete, so it's no more "Under construction". The last one to
describe was an unusual IBM Power
Series 850, a computer which was powered by PowerPC
processor, used in mid-1990s as a high-power workstation for
CAD, computer simulation and scientific computation
applications. Also, the front page has been changed and
minimized a bit, I also updated things here and there.
https support has been added for pleasure of tinfoil hats
fans. If your provider messes with content on pages, just change
a provider! You don't want a postman to read your mail!
||Added a Compaq
Clipper IA-1 (iPaq
IA-1) Internet Terminal made in 2000 for Belgian Internet
provider. It is in fact a small PC with wireless keyboard, small
LCD and proprietary operating system with only one program to
browse the Internet.

||Added a Highscreen
386 portable PC (I think
it's Highscreen). It is a portable computer from early 1990s,
used as control system. It has a typical, desktop internals, but
the casing contains LCD panel (VGA resolution, grayscale) and
detachable keyboard. It was used as a control/measurement system
for some industrial testing device.
||Acquired a Fujitsu
notebook from 1998 powered by Pentium I, a typical portable from
the age. Updated Power
Macintosh G5, as I restored another unit, in even worse
state. Got one more terminal and portable, so they'll be in next
Atari Mega 1 - A
professional version of 16-bit
Atari ST computer, with 8MHz Motorola 68000 processor and
1MB of RAM. Additionally, the computer has an Atari SH205 20MB
hard disk. These computers were used in multimedia authoring,
DTP, as CAD stations or, thanks to the MIDI interface, for music
production driving synthezisers.
BEMZ Bajt (Byte) computer, made in Belarus in late
1980s/early 1990s. This is a ZX Spectrum clone made using TTL
chips and programmable ROMs. It was sold as computer, and when
became obsolete, as a TV game. It has quite comfortable keyboard
and additional sound synthesizer.
||Added a network card for
Macintosh Performa 6200/200.
Can be seen in its
||Acquired an interesting mass
storage device from 1980s - an IOMega
Bernoulli Box. This
magnetic disk drive allowed to store 10MB on a removable
cartridge. In the era of 20MB disk drives it was a huge
expansion, especially that it was much faster than tape
streamers (SCSI interface) and allowed to access any data part
without waiting to rewind the tape.
||Added Power Macintosh 9500 - a
high-end Apple computer from 1995 with PowerPC processor, large
amounts of RAM and PCI slots. As a multimedia computer it has
significant upgrade capabilities. In late 1990s it has been
upgraded with G4 400MHz processor and 128MB of RAM, additionally
2MB video board has been replaced with a 16MB accelerator and
100MBit network adapter.
The computer had to be restored including joining broken plastic
parts. However, by using proper chemicals it was possible, in a
significant time, to restore it.
Canon StarWriter 95, this
is not exactly a computer, but rather a specialized
microcontroller-based computer system for word processing with
text editor, spreadsheet and scanning program to import
pictures. Everything on around 256kB of RAM. and the
double-density floppy drive as the only storage.
The machine has a small LCD screen and an ink-jet printer to
||Happy new year.
Alphatronic PC - another Z80-based microcomputer with 64kB
of RAM and BASIC, as well as with CP/M support if disk drive is
connected. This computer wa snot much successful and was made
only for a short time.
||Added a Swedish
unit built by German Loewe in 1992 on the base of
Multitel D design.
The Swedish version of Bildschirmtext (like more known French
Minitel) service was not as popular as BTX was in Germany, so it
was quickly shut down after a bit more than a year of operation.
Contrary to the German equivalent, it looks like chip cards were
used to "log into" the service, not phone number.
||Added a Macintosh
Powerbook 165c, the
first Apple notebook with colour display from 1994. Although it
was in my collection for longer time, I finally managed it to
power on. It has 33MHz processor, 8MB of RAM, and 120MB SCSI
hard disk. The 256-colour picture is shown in a small LCD screen
with 640x400 resolution.
Because any way it's Apple Mac, it's in Apple
Datassette 1531 - an
original tape recorder used with
Comomdore 16 and
Plus 4 computers.
||Added the computer sometimes known
as the first laptop: Epson HX-20.
Maybe not a "clamshell" type laptop, but definitely portable
computer. Its size is like A4 book, it's battery-powered and has
built-in printer, LCD screen and microcassette recorder. Two
6301 processors clocket at 0.631MHz are running this system, it
has built-in BASIC interpreter and monitor. There is only 16kB
of RAM, but it can be expanded with modules.
LTO Ultrium streamer,
similar to DLT but with some newer technologies. These tape
drives are used even today in servers for backup purposes as
they can fit even a few terabytes to one tape cartridge.
Additionally, a BIT
Computer PC from around 2000. Contrary to AMD or Intel, this
one has VIA/Cyrix processor.
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.
||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..
||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
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.
||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.
||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

architecture. Totally not like common Z80, MOS or 8080-based
||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.
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.
||Added a Z80-based LED display
driver: Transled, a newer version from early 1990s.
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.

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.
||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.
||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.

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