Simon Owen has written a program that can control the uPD765a floppy disk controller. This makes it possible to read or write normal PC floppy in a different way. The latest version of his program makes it possible to read and write a floppy in a normal PC and then use it in the 1581 3,5"disdrive from Commodore. This program can be used with Windows 2000, XP and 2003.
