Hello all,
What started as a "Sound Board Interface Error" has ended up as a non-working Tron board - and it's all my fault.
Before I explain, I've replaced the original ribbon cables with new ones, and it has an Arcadeshop switcher and HS Save Kit (for the last five years).
Here's the scoop:
I was trying to figure out the "Sound Board Interface Error" problem. The LED and self-test showed a fast-flash, indicating that the ROMs were at fault. I obtained new ROMs and seated them, but there was no change. Swapped out the Z80 on the sound board, no change. I thought that maybe I'd misaligned one of the ribbon cables between the sound and middle boards, so I swapped them by one pin. That's when the ribbon cable burned up and the game stopped working.
I've replaced the burned ribbon cable, and it still won't boot. I keep getting the attached garbled screen every time it comes on. I don't see any immediate evidence of burns on the board, but something is obviously not right.
I've seen this screen on the net on other Trons, but can find the solution. Any ideas?
Thanks!
Blaine
