Hi all, I'm chasing the Youtube video of the PDP-7 at Bell Labs where
people are using it to draw circuit schematics. This seems to show
the Graphics-2 module that, I believe, was built at the Labs. Can
someone e-mail the URL? I've done some grepping but I haven't found it yet.
Thanks, Warren

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.
Cheers, Warren

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).

Oh! I've found the right set of photos to make a good case this is a
PDP-7...
https://docs.google.com/presentation/d/1lNmjaJhuqKSbpDU96sc3Kia3d-Ag0DVylMzW6APdWEY/edit?usp=sharing
has an early version of a slide I'll be using in my talk next month.
Comments?
