Computer Museum Summary

Museum of Computers is part of the Computing Center at the Slovak Academy of Sciences in Bratislava

The museum maps the history of computing in Slovakia in the context of Czechoslovak, East European and World development and exhibits more then 800 objects (computers, peripheral and network devices and their parts like printed circuits boards, integrated circuits etc.) as well as many „historical“ books, manuals, magnetic tapes, diskettes, CD/DVD ROMs, and other documents on the Information and Communication Technology.

The Museum is not only a nostalgia of the old days of computing, but also demonstration how  computer technology changed over the last 60 years – from the vacuum tube machines to smartphones with complex systems on a chip or supercomputers with many powerful microprocessors.

How to get here: The main (but not best) entry is directly from Dubravska cesta (approximatelly 150m from IBM garages on the way to SVU (School of Applied Arts)). Ring the bell at the gate. Another entry is from the SAV campus, the one floor building behind the Computing Center (Výpočtové stredisko) staircase behing the entry to Computing Center and to the right 50m (ring the bell).
