    It works!
    You can combine:
    - X-Pander 3
    - Datel MIDI interface
    - Ultimate 1541 - II+

    For the Datel, set the DIP switches ON for IO1, IO2, and both POWER. All others
    OFF.
    For the Ultimate:
    - set the DIPs to all on
    - disable any cartridge emulation
    - disable RAM expansion unit
    - in Audio config, don't have any SIDs in $DE00 to $DFFF

    Hi There,

    I'd like to be able to use a Datel Midi interface cartridge alongside an
    Ultimate-1541-II for cynthcart.

    It appears cynthcart's prg ought to be able to run from the U-1541, but I
    suppose it could alternatively be a third cartridge.

    I'm evaluating either the X-Pander 3 from RETRO innovations, or the Mini
    X-Pander+ by Arkanix Labs.

    My preference would be:
    U-1541 (running cynthcart.prg)
    Datel Midi cartridge
    on the Mini X-Pander

    -or-

    U-1541 (running cynthcart.prg)
    Datel Midi cartridge
    on the X-Pander 3

    Alternatively:
    U-1541 (switched off, but plugged in)
    Cynthcart cartridge
    Datel Midi cartridge
    on the X-Pander 3

    I'm wondering if anyone can offer experience or rationale for why any of the
    above will/won't work.

    Cheers!
