I have a Warrior, and my Warrior uses TO-3 transistors as the audio amps.

The sound board looks very similar to a Space War, off the top of my head it
looks like there is an op-amp where I would expect a leaky transistor to be.

IIRC Sundance audio looks a lot like a Space War board, so my guess would
probably be Sundance.

That and I think there are too many Roms for a Space War. It only use 2 2716s,
so would only need 4 2708s.

An ex-Cinematronics tech once told me that when Cinematronics bought Vectorbeam
they got a sh$t load of those ROM boards.

Larry Rosenthal laid out the daughter board to take advantage of a big surplus
of 2708s floating around at the time. It seems the new "single supply" (oooww!
aaaahh!) 2716s and 2732s were out and nobody wanted to place three level power
supplies into their new designs, so 2708's were going for pennies on the dollar
on the surplus markets. Vectorbeam designed the board once, and used it many
times to take advantage of the prices.

Cinematronics used it for the same reasons when they got hold of the boards.

Sundance could easily have been shipped with 2708s.

I'm thinking Sundance. (Though am kinda hoping for something exotic like Rocket
Racer or Oops! or something... :-)
