Yes, it's a pretty interesting project, but as Asbjorn says he doesn't expect anyone to actually build the thing. But if you could reduce the component count and print a couple of PCBs... JiffyDOS compatibility would also make it even more interesting. On a similar note I've been thinking about how to connect an IDE drive to the C64 using no active components, only cables and connectors. I think I've figured it out, but I'm not sure if it'll actually work: C64 IDE User Port PB0..PB7 D0..D7 User Port PA2 /CS0 Joy 2 b0..b2 A0..A2 Joy 2 b3 /RD Joy 2 b4 /WR /IORDY is tied low, D0..D7, A0..A2, and /RD or /WR are set up, and then you strobe /CS0 to read or write a register. This isn't quite according to the IDE spec, but it seems like it might work. I think I saw a spare IDE cable in the junk heap at work... -- ___ . . . . . + . . o _|___|_ + . + . + .
