I have a working pcb for sale. Thought it had the rotary joystick connections, but it doesn't. Looking for $45 shipped.
I will consider trades for other rotary games.
Is there anywhere/anyone that could look at a TNK III board. Has some graphics glitches and won't register credits. Basically, it's just a glitchy demo. I already cleaned all the pins on the entire board--made no difference.
