Copying from a floppy to an SD card?

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. 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.
