No one hates you...I don't think... 
Remove all connectors on the MPU except J210.
Power on.
Now what are the LEDs doing?
LED201 is the blanking LED. It should go off a few seconds after boot. If it stays on, the CPU thinks something is honked up that may cause damage to the game.

Quoted from dlbuller:Thanks for the suggestions everybody. Maybe it's because I'm stressed about moving or maybe it really is that I'm pissed about Champion Pub dying day 1....might just jump ship on all my pins. Got too much crap going on and I basically want to just sit and do nothing. Lol.
Time to put things down and chill a little. It always helps me to rest the mind for a while, then reattack a problem.
The blanking signal originates at the ASIC. It holds the AV board and the driver board in reset until power stabilizes and basic initialization of the CPU software completes. The signal goes thru R90, U5, and U21. All of those would be suspect in addition to the ASIC, but I wouldn't go there yet.
Use your logic probe to see if the data and address lines on the 6809 are toggling. I suspect they will be since the DIAG LED is pulsing regularly. But, it's important to know.
I assume that the DIAG LED is pulsing at a constant rate vice flashing a code?
