My goal on the Tic Tac Toe machine was to build an exact replica of the Don Lancaster
1971 design. I have 2 of the MC789 inverters so I could build one unit.
Where would one find the write-up of that? I might have a few of
those chips in my junk bin (from a hand-wired TI-980 peripheral), and
it'd be fun to build one.
