Bally 6803 MPU

[Game On]

Hi all.. I have a Bally 6803 MPU. it boots fine Music and speech is fine but I strongly suspect the switch matrix to be faulty. Does anyone know where I can get a replacement board, original or re-make, or a repair service for these MPU's? I dont have a test rig and without it is almost impossible to fault find.

Thank you

Thank you but i am sure the switch matrix is bad when i test the individual crosspoints they dont register with the MPU. I am trying to find somone who can supply a replacement or repair mine as i have no test kit. Any ideas?

A company called Swemmer did make a repro 6803 board but that was years ago and I don’t know if they are still available- so that’s probably not much help….

You might find repair tips here though http://www.pinrepair.com/6803

My Lady Luck has same board and that has issues too hard to find someone to repair
