RE: OT: I,Robot help

There should be four 82S137 PROM's on the main board.
One off these was the culprit on my set so this might be a good place to
start.

To keep it vector, I'd like to second Jeff's request for help with a Star
Wars boardset. It seems to play okay, but when I put it through the test
mode it reports "Matrix Errors" (or is it "Mathbox Errors", I don't
remember). Which board of the 3 board Star Wars set is most likely the
culprit? Or if it can be isolated further to a particular chip, that would
be helpful too. Thanks,

Joe
