OutRun Rev.B - Graphic sprite error

« on: September 26, 2015, 08:14:49 pm »

Anyone with Outrun Rev.B board knowledge?
Board: 837-6063-01

Done until now!
* Voltage check (Both from PSU and on board on different checkpoints)
* Have been reseated all the eproms
* Onboard test gives me ALL GOOD status

Any suggestion where to look next!?
Have the Outrun Schematics, but not sure where to look next, what area is sprite related!?

GO!
Cheesy

Page 11 looks like sprite eproms

Games don't typically do self test on video eproms so you might just have a bad eprom in the matrix there. I think you would see more issues if one of the transceivers were bad.
