NOW . . . The interesting question is whether the firmware versions you have
support the ROCKWELL CMOS versions or only the NMOS parts. Rockwell made
the AIM 65 its evaluation system for their entry in the 6502 market, but
their CMOS version is the one whose instruction set I thought was the best
of all of them. If your AIM boards have the assembler and BASIC interpreter
for the CMOS version, that's something to hang onto since it's still current
as far as the compatible cores are concerned.

They are. Two are optional BASIC and the other is
optional Assembler.

Dick,
That's an interesting question! I wonder what the difference in the
software is? I don't think I've ever heard of a CMOS AIM 65. The BASIC
comes up as ver 1.1. I didn't see a version on the assembler. The ICs
containing the assembler and BASIC don't have any special markings. They're
PN is the same as the PN of the two standard ROMs except one digit is
different.

CMOS versions of 6502's by various manufactors had
illegal/non-documented instructionset enhancements, The problem was that
different manufactors
divised different enhancements so the are not very compatible.
There must be docu's out there outlining the non-documented instructions
of various manufactors, Homecomputer magazines from the UK liked to run
such info, Unforunatly I cast out a lot of these magazines.
