Looking for a working MCR SSI/O board for a Tapper. I've got the other two boards in the Tapper boardset, but I'm missing that one to complete the set.
As alluded to previously, the SSIO is a general purpose I/O board used across all the MCR series games with minor modifications from system to system. As a general rule, the SSIO from different games may be safely swapped for testing purposes.
Customization of the SSIO for a particular game is accomplished through four 4K EPROMs in locations A7-A10.
