Not much. Put an ST506 controller into a PC. ST506/412 was the defacto
standard on PCs until IDE. although most PC people erroneously refer to
the cabling and interface as "MFM". The controllers used by IBM in the XT
were made by Xebec.
Once you have a controller and drive in your PC, you can write the code to
read and write sectors to be able to copy a drive. If you go a step further, and parse the DIRectory, then
you could
selectively read and write sectors to be able to transfer files.
