As the title says, I was wondering if anyone has a bally 17 or 35 mpu board they would like to swap for a Gottlieb sys 80a mpu.
the Gottlieb board is in very good condition, i dont know if it works or not as i dont have a machine to try it, it has no rom for a specific game,
I bought Rollerballs boards from his HH and it works out the mpu board was a sys80a not a sys80 so its no use to me.
I would like to swap it for a bally mpu that is non working now i have the taste for repairing them.the board does not require any of the socketed chips.
some pics of the sys80a board.
