Testing a Millipede board for a friend. In test mode it gives EA, P0 & P1 faults. Controls do nothing. Switched EAROM with good chip, same issue. Reseat chips, same issue. In attract mode, start buttons blink rapidly. Credit up game and will not start. Attract mode looks like it should. Checked all eproms and they check out good (checksums). Any idea what the issue could be? Not sure what to look for next, don't want to do any more damage just poking around.

earom and both pokeys are your errors, start by checking voltages and swapping the pokeys

earom error should only prevent high score saves, i think it will still run properly

pokeys will cause all kinds of problems, including your controls being out
 
Definitely sounds like Pokeys. If you have another Atari PCB, there's a good chance it has one, or maybe two, which you could swap around to diagnose your problem.
 
Update: tried different pokeys, earom and same issue. Got controls to work, had dirty edge connection.
