>Two display hacks run on PDP-7 serial number 129 with the Type 340 XY display option. The 340 has a P7 phosphor has a slow decay which gives Munching Squares an eerie afterglow. Both programs read the left switches to modify patterns. A small AM radio was used to pick up RFI from the Type 347 controller. For the MIT AI lab hackers the Munching Squares "music" was referred to as Munching Tunes.
Here is the 340 Vector Graphics Display Programming Manual:
The amazing retro-hacker Lars Brinkhoff has been working on emulating the 340 and its beautiful P7 phosphor with GLSL shaders for the simh PDP-7 emulator:
