The early one for the circuit simulator is definitely on a PDP-5 and I
presume the Graphics-1 display. You can see the PDP 5 letters on one of the
cabinets. How do you know that the music was composed on the PDP-7 that
appears from 9:20-10:30? Cool paper tape feeding sequence, though, you
gotta admit :) (well, unless you waited for far too many of those to run
back in the day).
