Does anyone know of a way, from Linux, to determine the particular
species of one of those cables? I bought mine years ago and no longer
remember which it is (and it isn't marked). I assume it's XM, since I'm
sure I intended it for use in Linux when I bought it, but I'd like to be
sure.

Somewhere I picked up the idea that for that you would need a cable that
connects, not only to the serial IEC port of the drive, but to a
parallel port which you must DIY on the drive. Would someone mind
chiming in here -- I don't understand how that would do anything other
than making the transfer faster? I know that on the software side you
specifically need nibbling tools, like mnib.

The SD card devices all use Ingo Korb's SD2IEC software, as far as I
know.  The main source of documentation I know of is at
<https://www.sd2iec.de/gitweb/?p=sd2iec.git;a=blob;f=README;hb=HEAD>.
