Sorry, guess I should have been more specific. The (drive that was
0:) drive spins, and the LED comes on, but the machine still says "Cass?".
The other drive (which I had replaced it with) attempts to read from the
disk, and either displays "Diskette?" or nothing if there's no disk in the
drive or a disk, respectively.

Maybe this is part of the problem. Neither drive has a terminator on it.
What resistance is it? I could probably try making one out of spare
resistors or buying a new resistor pack for it.
Still, it seems strange that it was probably used without a terminator,
and that's the cause of the problem.

I haven't seen anything in xtrs that lets me use a physical disk, only
disk images. Does anyone know if I'm mistaken and xtrs will read disks?
