I'm occasionally called on to transfer some of the C64 floppies. I have
a 1571 and have cobbled up the XM interface connected to a DB25F
permanently mounted on the drive. That way, I can use a "straight
through" cable to the parallel port of the host PC without thinking
about what I might need. Works fine; I get use it about once every 3-4
I suppose it might be possible to rig something more elaborate up using
a small MCU and a USB cable, but the need doesn't justify the effort.
