Multihead for debugging full screen apps is/was pretty sweet. Now we just use ssh or a remote debugger. I haven't finished the video, fingers crossed that he hooked 4 joysticks for multiplayer pong.

Didn't realize how wholesome 8bit guy is, great channel.

Id soft folks were using 2 graphics cards, an EGA/VGA and an MDA one to do multihead debugging. It was possible because the two card technologies actually mapped their frame buffers onto two separate address ranges. Cool stuff.
