Star Wars Math RAM (5F and 5H) and Mathbox Ready errors
Hey,
My Star Wars Cockpit is having some problems... when I try to play a game, it starts, but there's never any enemies, and from the test mode, the first test gives me:
Math RAM at 5F
Math RAM at 5H
Then going further in the test, I get:
Bad Mathbox Ready Line
I've replaced 5F and 5H, but that didn't make any difference, so I think there's something wrong with the circuitry further up. I assume that the Mathbox Ready Line is bad because of the same problem (or the RAM problem is caused by the Ready Line problem).
So far, I've done some searching and came across suggestions to replace 4F and 4H, so I did, but it made no difference. I also swapped with a known good AVG chip, since I've had several of those cause funny problems, but that didn't help. I used to have an upright, and back then I verified that the problem is on the main board (middle board in the stack). The voltages are good and the monitor is good.
I'm running Mark Spaeth's SW/ESB multi kit. Any ideas on what I should check next?
Thanks,
DogP
