Thank you for posting. A PCB would be fun but I'd be inclined to do a shrink, moving away from all the jelly-bean logic. I'm pretty sure a KimKlone clone (!) could be done with just a 128 macrocell CPLD, a '574 and the 2 uCode EPROMs, plus the VIA, the CPU, and the stock memory complement (RAM/ROM).

Do you ever visit the forum at 6502.org? There's a smallish discussion about KK there... http://forum.6502.org/viewtopic.php?f=9&t=1487

I do visit, but hadn't seen this thread. Sorting through it.
