Trying to troubleshoot an old Battlezone arcade game. Anyone got a 6502 CPU lying around?

I have dozens.      I've fixed quite a few Battlezones and never seen a bad CPU.      It's not a common mode of failure.

Got the machine going. Replaced all the ROM sockets, CPU Socket, and socketed the RAM while i was at it. Burned some new ROMs while i was at it. Looks like a combo of at least one bad ROM and sockets. The main board is working now. No audio but i traced that to a bad LM324 so i need to get a couple of those and socket them too.

Hey Jerry, 

Are you uploading photos or a video of the project anywhere? 

Would be cool to see the old equipment. 

Glad you got it running

Cheers,
