If you have the BackBit Chip Tester, the CornBitXL is fully reprogrammable with four 16/32KB ROMs of your choice. This is made possible by the extra pins that hang over on either side. The extra pins only take up a few millimeters of space, so they should not get in the way of other components.
Slot #1: 317053-01 PLUS/4 FUNCTION LOW
Slot #2: 317054-01 PLUS/4 FUNCTION HIGH
Slot #3: 318005-05 PLUS/4 & C16 KERNAL
Slot #4: 318008-01 1551 KERNAL
To reprogram with the Chip Tester, append four 16KB or 32KB binary files into a 64KB or 128KB file, respectively. Then those 4 ROMs will be available with the 2nd and 3rd DIP switches. Make sure to do a binary append.
