Quite a long time ago (74?) Edinburgh University's comp sci dept had a PDP8
which we hooked up to a 'scope in the same way. The '8 wouldn't have been fast
enough for quite so flashy a demo, but we did have a lot of good video games
running on it such as 'tanks' and 'snooker'. (input was via a couple
of trimpots
on the A2D)

Unfortunately no-one thought to video it at the time, but we did preserve quite
a lot of binaries (via paper tapes) and an occasional source.

I remember one program used timing loops to generate RFI and output sound
on a nearby AM radio... another program sampled an on/off switch to decode
morse.

Not bad for a 4K memory machine.
