They mention a Graphics-1 device, so maybe I'm getting this confused with the PDP-7 and the Graphics-2.

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 cabinet= s. How do you know that the music was composed on the PDP-7 that appears fr= om 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)= .

Oh! I've found the = right set of photos to make a good case this is a PDP-7...


has an early version of a slide I'll be = using in my talk next month.
