Here's what I've done so far....
Tried a different transformer
New big blue
Tried a different arii...I also caped the arii and change the resisters
I think its a board issue
So if I increase the voltage on the board to 5.15 it locks up durning attract mode or when playing almost always on the third board. If I decrease the voltage to exactly 5.0 (measured at the board and the 6205) it plays longer...but will eventually lock up. I've replaced the 6502 (cpu..it might be a 6205..posting from my phone) and the 2 pokeys
There are no RAM or ROM errors in the self test. I've cleaned the edged connectors and spent about an hour going over the pcb looking for smoked parts and touching up some solder
I thought it might be a ROM issue but its weird that as I decrease the voltage down to 4.90 the stability increases. My ROM burner was supposed to be here friday but never showed up
Is it worth a shot to recap the pcb?
Any other suggestions?
Thanks!
