Cartridge Expanders, Ultimate-1541-II, Cynthcart, Datel Midi

[Mike Horgan]

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!

Update:

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
