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

CORRECTION:
Running simH on a $9.95 Next Thing Co CHIP.
1. I built an RL01 disk with RSX11/M that boots within simH using the
files I found online.
set cpu 11/40
set cpu 64K
set rl0 writeenabled
set rl0 rl01
set rl1 writeenabled
set rl1 rl01
set rl2 writeenabled
set rl2 rl01
set rl3 writeenable
One last comment...I will edit and clean up the directions for anyone who
wants them in the future here:

thanks again all.
