RTL Logic

Michael, to get a version running, you could "build" an inverter on a 14 pin header with the inverter pinout you need. I realize it would take a couple of 6 resistor packages and six transistors. At least you could replace the "part" with the real one when you find it. It might actually be a conversation piece to show people what went into the RTL chips themselves. Just a thought anyway.

best regards, Steve Thatcher

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.
