Dual 6532 adapter board
Replacing the 6530 with a 6532 and ROM and some glue logic is a well known method nowadays.
Eduardo designed a PCB that replaces both 6530-002 and 6530-003 on a standard KIM-1 and of course his replica with a PCB that fits in the IC sockets of the 6530’s. That makes a KIM-1 completely operational!
See this github page for the design.
