* [TUHS] Video of PDP-7 with Graphics-2? @ 2019-08-02 20:14 Warren Toomey [not found] ` <e00fc7d7-7182-1d0f-261e-6701af92c690@deitygraveyard.com> 0 siblings, 1 reply; 4+ messages in thread From: Warren Toomey @ 2019-08-02 20:14 UTC (permalink / raw) To: tuhs 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 ^ permalink raw reply [flat|nested] 4+ messages in thread

Thanks Jim, Is it this one? https://www.youtube.com/watch?v=iwVu2BWLZqA They mention a Graphics-1 device, so maybe I'm getting this confused with the PDP-7 and the Graphics-2.

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).

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.
