I don't specifically recall a "math board" in that one, but we didn't see too many of that Logic Set come through for repair. Wouldn't surprise me a bit (get it??) though. The Atari AVG logic sets were all doing 16-bit math at 12MHz, remember the mighty 2901s on them? With the state machines for them decoded from bipolar PROM? Battlezone, Red Baron, Tempest.. all had essentially the same mathbox.
Not like the mathbox on the Atari games, this was a strange critter. It was an analog gizmo, bunch of op-amps and bilateral switches and whatnot. It was hooked to the processor with a ribbon cable and to the XY monitor with analog connections. It was too complicated to be like the stroke generators in Cinematronics monitors, I think it was probably worked like that scope clock circle generator.
