    I use a Passport MIDI interface with my Mac Plus. It is extremely
    simple, with one MIDI in and one MIDI out. It does not require an
    external power supply. It comes with a DB9 connector, so you do need
    an adaptor (DB9 to DIN8). The key point, though, is that it does not
    need the +5 volt pin that the new connectors don't have. I guess it
    powers itself directly from the signals. It operates at 1 MHz, is
    about 2 inches by 5 inches, and comes with two MIDI cables. I use it
    with Megatrack XL, Sound Designer, DMCS, etc. I bought it bundled with
    Megatrack so I'm not sure how much it sells for.

    I recommend it if you want a simple, hassle-free, power-free
    interface. Now that I just got a second keyboard, I'm starting to miss
    the 2nd set of ins and outs which the Opcode interface, for example,
    has.

    The model number is MH-01M.
