Just a very quick post here.

It is possible to upgrade the floppy drive on the mATX ST to a full 1.44mb HD drive by using @exxos’s V7 upgrade board.

To get it to work you need to connect P1 to floppy drive port pin 10, P2 to pin 12 on the floppy port and then connect D0 to the HD detect pin on your floppy drive.
