I've been using the two bit diagnostic tool and have successfully fixed the colors and the character display. I'm now stuck trying to get the sprites to display. This is one of the diagnostic screens that should have sprites displayed in each box points to 3F or 3H. Both are new. When I boot using the ms pac-man eprom provided with the diagnostic kit the demo starts and I see dots disappearing but no sprites there either. I saw activity on 1F, 2F, and 1H which are downstream from 3F 7 3H. I checked all the possible causes in MikesArcade pac-man troubleshooting guide and everything looked good there. Any suggestions on what else to check would be greatly appreciated.
