Good question! Not that I know of... BUT that doesn't mean it cann't be applied to
other games or PCBs I routinely use it for early Bally pinball boards (level 17 & 35).

I have done a bit of SA work on Pac boards but most of the problems are easier to find
using a scope than doing SA on this system, atleast for me.

The 50 pin connector was only meant for a pre chip test of the PCB to ensure all traces
were free & unobstructed. Atleast that is the word I got from several Bally/Midway reps
over the years.

Hmmm, I'm very curious in this device too! Perhaps it is the Kurz Kash Test Fixture
(TF-650), which is not really a excersizer but simply a power up/test facility to
connect a board to buttons, speaker & monitor. The fixture was meant to be used with a
SA setup and KK sold a cinematronics exorciser (which I've never seen only advertized in
there literature).

The only other thing in this vein is the Fluke 9010A Microprocessor Troubleshooter.

As mentioned SA has it's limitaitons and is better suited to simpler circuit designs.
It is also something that you will only drag out for multiple boards, tougher problems.
 Believe me, I have 3 (KK, Cat Box & Bug Trap). I have the notes KK issued if anyone is
interested....
