I got another S&S- this one works, but is dirty and many buttons are broken. No Word Module. I'll swap parts and make one good one. Date code is MTA4078, and the date codes on the chips are several weeks earlier than the other unit. Board is revision 1D versus 3G on the other. An obvious change is the trace to pin 18 of the VFD has been cut and a resistor put inline. Flux around the display pins, so I guess it was replaced. Speaker wires were also resoldered. Everything else looks stock. Chips are the same numbers as the other unit, but earlier date codes.

Also got a Maniac game, designed by Ralph Baer (RIP).
