The KimKlone impresses me quite a bit; was it just a case of a thought like: "oh, if I did this and this, I could extend the address space..." and then a burning desire to see it work, or did something else motivate this?

  I was in my twenties, I was hugely turned on by the electronics I was learning, and I was bursting with creativity! There's a little bit of Back Story explained here, especially the "my KIM" section at the bottom of the page. http://laughtonelectronics.com/Arcana/KimKlone/BrideOfSon%20KK%20Lancaster.html http://laughtonelectronics.com/Arcana/KimKlone/BrideOfSon%20... Also I'm a Forth fan, and when when I realized the counter/timer of a 6522 could be tricked into serving as IP for a 9-cycle machine-code NEXT instruction, the idea amused me immoderately (LMFAO) and I had to build the darn thing! :oD Previous HN thread here: https://news.ycombinator.com/item?id=3070169 https://news.ycombinator.com/item?id=3070169

    Have you ever considered making a PCB of the thing and making it available to others? Hell, I wonder if it'd even be possible to make an expansion model for old 6502 machines using this technique. It's very clever. Thank you.

      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 http://forum.6502.org/viewtopic.php?f=9&t=1487

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