you can find
schematics of the original KIM and one that can be built with a 6532. There
might be enough info there in order to replace the 6530 with a 6532+EPROM
daughter board.
I've seen that before - nice writeup on what has to be done to make a
KIM from easily-available parts. I think the hardest thing is to find
a suitable keypad. If one were to hand-wire one, one could even use
Radio-Shack protoboards with the 22-position 0.154" spacing edge
fingers if one had external accessories to attach (or use 0.1" headers
and ribbon cable for "modern" expansions). Easy to max out the memory
these days... one chip!
