Hi all, I'm chasing the Youtube video of the
PDP-7 at Bell Labs where
people are using it to draw circuit schematics.
A Bell Labs video? The only Bell Labs video I remember seeing that had
someone doing circuit schematics had it being done on a PDP-5. The -7
was
shown later doing music stuff. (That's the
-7 that I thought maybe Unix
started life on.)
Thanks Jim, Is it this one?

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