A cool three part video of a portable apple one.

    In part two he reveals that he uses the Propeller to generate composite video and read his keyboard.

    I can't help but wish he would make a version that uses the Propeller for the CPU and PIA functions as well. It would certainly run faster. Probably won't happen, though. It wouldn't be in the interest of Element 14 to sell fewer chips, connectors, sockets, boards, and wire.

    He's running a clone of the Apple 1 ROM -- not likely he wants to reverse engineer all that.

    I don't think we have a complete 6502 core yet.

    Woz made use of the Decimal Mode on the 6502, which is one limiting factor here, unless he didn't on the Apple I ROM.
