Anyone have the schematics for a police trainer board? I've been probing with my logic probe for hours, but can't figure out where some of the traces go and schematics would help me greatly.

Thanks.

The ones in the manual are very incomplete and dont show what I need to see.
 
What's in the manual is what there is I believe. What problem are you having?
 
The board won't boot. I'm getting a solid red and green LED. I probed the data bus buffer chips and they're latched in high Z mode so I think the board just isn't booting. It's odd because there is actually data strobing on the address and data busses. I found a bad rom at U110 and I have a new one on order from hobby roms.

I just picked up a sharpshooter board and tried swapping the roms from that board into the broken police trainer board and it didn't boot up. I'm not sure if sharpshooter is just a rom swap for police trainer or not do you know? It appears to be the same exact board, but I'm sure there could be differences.
