Playing Space Invaders on a PDP-11

[mpatoray]

The PDP/11 series of computeres are quite different then the Altair 8080 and IMSI 8080 that where offered to the consumer. The PDP/11 is a 16 bit minicomputer series that was very popular with research organizations, Bell Lbas had tons of them and Dennis Ritchie co wrote UNIX for use on the 11.

The IMSI commands a high price because it was "The computer in War Games" The Altair because it was the first packaged kit computer that you could buy, and the first one Bill Gates and crew wrote a BASIC interpreter for. Neither computers where very high power but hey we are talking 1975 and most people had never seen anything like it on a desk in the home.
