We thought of this potential problem of using a straight gender-changer when we did the pin assignments, hence why pin 23,24,25 are not connected to GND since the A1000 has +5V on pin 23. Double-check with the pinout on the schematic and don't plug in anything else on the A1000 with such plug without double-checking pinout. It'll most likely damage your CIA chips.

Also on a stock A1000 you have very limited amount of memory so make the FAT-partition smaller, like a few hundreds of megabytes or so. A big partition allocates more memory from the system.
Yikes. I was about to just plug the SDBox into it.
