r184 r199 22 22 23 23 <p>Today's kids think of the latest mobile devices when talking about "mini computers". In contrast, in the 1960s and the early 70s, a computer was always huge (like our <a href="univac9400.shtm">UNIVAC mainframe</a>), thus a 300kg computer was "mini". Early computers are well worth seeing due to their enormous size and the nice transparent auxillary devices. 24 <br />There is a very important computer family that finally lead to today's (personal) computers: The development of the "Mini" computers from Digital Equipment Corporation (DEC), series PDP 8. The museum owns a complete production run from that devices: From the PDP 8 (also called Classic 8), year of manufacture 1965 to the PDP 8a (1975, this one is less important so it is located in the archive).24 <br />There is a very important computer family that finally lead to today's (personal) computers: The development of the "Mini" computers from Digital Equipment Corporation (DEC), series PDP-8.
