The 6530 and 6532 are very close in functionality.
Nearly the same timer, 2 8 bit I/O ports, RAM.
With an external ROM and some clever addressing logic many 6530’s have been replaced with a 6532.
Here some examples:
- KIM 6530 to 6532 for a KIM-1 clone
- KIM 6530 replacement board
- Allied Leisure pinball machines
- 6530 replacement Commodore
- Gottlieb sound board
- Corsham replacement board for the KIM-1
- Eduardo Casino 6530 replacement board for the KIM-1
- Retrospy Technologies 6530 replacement
