I know of no way, probing only with the PC &
software, to determine which
type of X-1541 cable you might have. However, wiring diagrams for +all+
versions are freely available, and it shouldn't be any great effort to open
up and - with the help of a multimeter - examine a given cable and compare
it against the various arrangements.
The 1541-side parallel port is totally optional, and it is not required to
produce a working setup.
OK, so the presence of that parallel port has nothing to do with imaging
copy-protected disks, as I thought?
Now that I think about it, maybe some particular nibbling software (mnib or
the like) just requires the parallel port, probably for speed reasons or
whatever.
However, when coupled with an appropriate cable,
drives equipped with the parallel connector operate several times faster
than even the fastest non-parallel setups. That said, any of the X-1541
setups will tend to run a fair bit faster than a genuine Commodre IEC bus,
so unless you plan to do a +lot+ of transfer, don't worry about going the
parallel route.

I do a fair amount of cross-C64 work, but all of
it's on Linux.. here's
what I can tell you, much of which applies to MS/Win as well.
First you need a method of reading the original C-64 floppy into a .D64
(or

suite and one of the
various
X-1541
cables. These days, with modern multi-tasking OSes, I'd suggest
using nothing but the XM-1541 cable design. These may be purchased, or,
with a little time & effort, built up by the DIY-er.
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.
If you have one of the SD-based systems, simply copy over the image to
the
SD and you're good! I don't use SD card,
just original 1541 & floppies,
so
wouldn't have much help for that end of the
process. But I'm sure it's
very
well documented by the vendor of the SD-card
drive hardware - right? =)
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>.
