I'm repairing a ROTJ and I suspect that the code in PROM 9H (136030.116) which is an 82S129 is bad. Unfortunately the MAME ROM set does not include the prom code (it generates the VSYNC and VBLANK) and I don't have another board to copy this rom from. Does anyone have this code or can obtain it for me from their ROTJ?

Thanks,

Bill
 
If all else fails, you might email Elektron Forge. Alex repaired my board, so maybe he can help?


I'll send Alex an email. Never had this go bad before so I never had to get the code for it. You bet I will keep a copy of the code (once I get it) ... :)

Many thanks (again) to Joe Magiera for providing me with a spare ROTJ board to desolder the 9H prom and capture the code on my Data I/O.

I am attaching the PROM file here for posterity. 82S129 or equivalent.
