A documentaey film about first computers constructed and produced in Croatia (text in Croatian):
Life On 8 Bits.
(Presently only in Croatian. Translation follows soon.)
In the Virtual MMC you play games on a HP2000 computer (simulated)
from the 1970-ies, or program on it in Basic, you can play a Multi-user Dangeon
Game on a Sun 3/60 computer (real, serving you these pages) from 1986, or try
the Croatian computer "Eagle" (simulated) from early 1980-ies, or you can read a historical
overview, or study a lot of documentation.
On-line access to active machines:
HP2000 Access Timesharing Basic
For the access to the HP2000 Access Timesharing Basic system, as
it was installed in the Multimedia Centre in Zagreb between 1970-ies/1980-ies,
you need telnet. Further short instructions how to
access the system as Guest you will get after establishing the telnet
connection. If you wish to have permanent access and your own user-name, please
write to me (e-mail address at the end of this page).
For telnet access from Windows you need (e.g.) putty (https://www.putty.org/). (32-bit version: putty.exe.
Just download it onto your, for example, desktop. There is no installation,
that's it.) Start putty and enter 'Host Name' 'melior.irb.hr', 'Port'
2100 and 'Connection type' Telnet. Then connect :)
On UNIX or Linux (and Mac OS X) open a terminal, and enter
'telnet melior.irb.hr 2100'.
On Android mobile you can use (e.g.) ConnectBot (https://play.google.com/store/apps/details?id=org.connectbot&hl=en).
Change the protocol to telnet and set hostname:port to
'melior.irb.hr:2100'. (The usage of
ConnectBot is very simple, in the case of any problems read its
If you would like to access these telnet services over the WEB-a, this is
slightly more complicated. You need, for example, Firefox and Firefox Add-on
"BBSFox", which you can download from 'addons.mozilla.org' at https://addons.mozilla.org/en-US/firefox/addon/BBSFox/.
(Though when you install it, it works fine. I only do not know how to send a
Presently I am testing a more convenient WEB access (for the knowledgable,
'jutty' will be installed), but it is not ready yet.
After that you can access the HP2000 system by this link:
Remark: if the HP2000 system does not give a response from first, close the
terminal and try again. For some reason it happens sometimes.
The Philosophical Multi-User Dungeon
In addition to that, those curious can also visit the MUDroslovni MUD
(The Philosophical Multi-User Dungeon), developed during advanced courses
on the Department of Information Sciences of the Faculty of Philosophy of
Zagreb University, developed during the 1990-ies, on the original machine from
telnet grgur.irb.hr 4000
- On Windows, using putty adjust 'Host Name' to
'grgur.irb.hr', 'Port' to 4000 i 'Connection type' to
Telnet. In a UNIX/Linux terminal use telnet grgur.irb.hr
Web access: telnet://grgur.irb.hr:4000/ -
Remark: if you use BBSFox, you will not be able to see what you write, although
it is possible to play even in such a way.
Eagle - Orao
Do not forget to try working on the Web emulator of the computer Orao
(Eagle), developed by Hrvoje Čavrak (the access is direct over

The pages are being updated quite regularly, come back again, as there will
be much more additional documentation during and after the exhibition in the
Croatian School Museum. The intention is that the Virtual Multimedia Centre
becomes a permanent place.
