Hi Ethan
One can wire the 6532 and EPROM chip in place of the 6530. It does
require a little mapping because the selects most likely won't
be compatable but the rest should work. There is a fellow in
France that is doing this for Pinball machines.

Aside from being a "better KIM"? ISTR it was basically a KIM with a few
extras (oscilloscope output, a la the Poptronics Scopewriter) added. I don't
think it used the mask-programmed RIOT chips either, unlike the KIM, which
makes it (slightly) easier to fix if something goes wrong.
It does not use mask-programmed RIOT chips... one of the reasons I'm happy
to have a SYM-1 - no unobtanium ingredients.
