Look on Ebay for kits, then a cheap USB-to-TTL connector and you too can run Wozniak's best from your top of the line mac/pc. The disassembler is crazy powerfull given the size of the executable.
The same KIM uno (6502 emulation from Arduino Uno) runs KIM, a contemporary of Apple 1 (with much better documentation, check archive.org) and a masterpiece of engineering: Microchess from Peter Jennings (not that one). Microchess, was at the time (and arguably still is) software that is just so unbelievably brilliant thay it must have been recovered from the Roswell crash site, just like whatever Fabrice Bellard puts out these days.
Not saying that the 6502 was the best thing in the computer industry, but then again, yeah maybe it was.
