I've been making a debugging ROM board to test out
the various
parts of the KIM-1. It is based on taking over the KIM at reset
and running test.
So far I've got two test working. One is a basic, is it running test
that just blinks a light on the debug board.
The next is a test of the first 1K of RAM.
A little tricky to do without RAM.
I expect to write some more for the RRIOT ics.
If anyone has interest, they can follow me on the Vintage
Computer Forum or contact me here.
The board has 3 ttl ICs, a 2764/27128 EPROM, a couple
LEDs and a dip switch. Also a few pullup resistors and capacitors.

Dwight,
That is a pretty cool project. May I suggest you break it out on VCF into
its own thread so people can more easily follow what is going on? For those
interested in the original thread:
