Copying from a floppy to an SD card?

"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."

As I say, I'm only aware of using the second parallel port to speed disk
transfers, and in that capacity it's really excellent. If it has other
uses, that's new info to me.. since I never need to copy protected
originals, I've never looked into it.

Once the hardware is in place, open CBM auto-detects the presence of the
parallel connection as an "XP-1541" setup, vs. XM-1541 using only the
serial cable. No further configuration is required, it just reads & writes
at like 4-5X the speed.
