The infamous game that begat Unix has now been made to run on a PDP-7 emulator with support for the Graphic-2 display system.
An interesting teaser! I had a search, and didn’t find this particular work but I did find a previous issue thread of yours with several interesting links:
I’m guessing that GRAPHIC-1, GRAPHIC-2, and Type 340 are related in some way?
And this 1968 classic (The Incredible Machine) was mentioned too:
It’s being merged to the http://github.com/pdp7-unix repository as we speak.
The Type 340 was DEC’s older display system, popular with the PDP-6. (Also related to the even older Type 30 for the PDP-1.) The GRAPHIC-1 is visible in the video you posted;if you have sharp eyes you can see it’s attached to a PDP-5. The GRAPHIC-2 was the followup, normally used with PDP-7 or 9 computers. I think they were both designed mainly by William Ninke at Bell Labs.
