Eduardo Casino has designed with modern tools, like Kicad and image software Inkscape a PCB for the KIM-1 which is as close as he could get to a Rev D.
Based upon images on the Revisions pages on this site.
On this forum64.de thread he published the design, and made all available on his github pages.
The PCB is an exact PCB replica of the KIM-1. It therefore requires 6530-002 and -003 RRIOTs, which are not available anymore (or use the Retrospy Technologies 6530 replacement boards).
