This reminds me of a ZX-81 (also cheap PC CGA cards) with the screen snow/flicker in order to save on cost and complexity. Cool stuff that I wish I could really do

Really good chiptune music to go with it as well

This sort of architecture was also not unusual in the commercial world as well. There were several computers with TTL CPUs as well as a few arcade (Cinematronics) games.

Via reddit user visionik:

"This game was a technology masterpiece in its day. The 3D engine was originally implemented with TTL logic chips (lots of little individual logic chips put together to make a 3D engine).
It was a technology masterpiece but a financial flop. Only about 1,000 were made, and only about 500 were sold. They did not do well commercially for three reasons:

* the "newfangled" 3D nature actually confused many players.
* the hardware was not reliable. RAM chips, ROM chips, and the special "hall effect" joystick all tended to die quickly.
* The arcade game market crashed in 1984 shortly after its release.

Due to the limited production run and almost 100% hardware failure rate in the first two years, very, very few I, Robot arcade games still exist. I am fortunate enough to own one - and it is a complete bitch to keep it running properly.
Despite the troubles it is an extremely enjoyable game to play.

The software was created by Dave Theurer - who previously coded Atari's 1981 hit, Tempest.
The hardware was designed by Dave Sherman.

Comment hidden because you are ignoring dag. (show it anyway)

This is double true. Unfortunately as a legacy of the olden days- our domain is with a registrar that doesn't allow adjustments to TTL. We're fixing this. Better late than never.>> ^brain:
You should have just lowered the TTL first.

I know there are still people stuck in razzleberry though.

Word. It's common knowledge that it can take up to 24-48 hours for a DNS change to propagate, but it's a surprisingly long wait nonetheless.
