hmmm, floppy drive controller. Not a lot of computing power in that though - is he using two micros?

I guess he built it for speed and exceptionally quick retreat to previous branch node.

Good tactic to beat egg-heads over-thinking the maze and poorly maneuvering it.

I bet that once his manuevering was matched, improvements to maze deduction could beat it.

Do they have a URL?
