Title: OutRun Rev.B - Graphic sprite error Post by: yocke on September 26, 2015, 08:14:49 pm (http://yocke.se/blogfiles/arcade/IMG_9517.JPG)
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! :D Title: Re: OutRun Rev.B - Graphic sprite error Post by: iankellogg on September 28, 2015, 07:38:32 am Page 11 looks like sprite eproms
http://www.arcade-museum.com/manuals-videogames/O/Outrun%20Schematics.pdf 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. |
