I used Lyle's updated version to show Spacewar on my PDP-8/a during this weekends retro event "RetroGathering" in Sweden. It works great!
I did two modifications to the code: 1. Use digital IO instead of the switch register so I could use hand controls to let the audience play the game. 2. Fixed a bug so that timer interrupts is turned on if the DK8-EP programmable real time clock is used. /Anders > >I just updated D.E. Wrege's Spacewar as follows: > >1.
