It is totally totally impressive that a hardware version of a software simulation of the actual 6502 was built. What about an 8080 or 6800? Or Z-80. Zapple V1

  https://en.wikipedia.org/wiki/Transistor_count#Microprocessors https://en.wikipedia.org/wiki/Transistor_count#Microprocesso... A 6800 or 8080 at the same density would be slightly larger, and a Z80 is more than twice as large. Even the first Pentium has almost 1000x more transistors.

  Well http://www.visual6502.org/ http://www.visual6502.org/ has the visual sim for the 6502 but also the 6800 and the ARM-1. I guess that means the full netlist for those two must be done too? If so I guess it'd be possible to do them in this way. Though I don't think they have the same obsessive fan audience that the 6502 has. It sounds like the process of analyzing the Z80 in a similar way is starting: http://www.visual6502.org/wiki/index.php?title=Z8400 http://www.visual6502.org/wiki/index.php?title=Z8400

  "Hardware version of software simulation" seems not to quite convey this. It looks like the software simulation actually simulated the original circuitry, using a netlist. The hardware is based on the same netlist; thus that simulation is of this hardware as much as of the original 6502. This new hardware isn't a simulation, though, but a discrete implementation of the real circuit.

  I would pay for a Giant Z-80.
