Using a PC 1.44MB Floppy as an internal Amiga Drive - Mitsumi D359M3

Modifications required to allow a Mitsumi D359M3 Floppy drive to be used as an Amiga internal floppy drive.

Move jumper from DEN3 to DEN2 to enable disk-change on Pin2 of the connector

Cut trace from Pin 34 leading to the IC in the centre of the board

Connect the right side of DEN3 to Pin 34

To change the drive to D0 instead of D1 that is the default for PC floppy drives - Cut trace leading to Pin 12 and connect it to Pin 10 instead.

Something I've considered trying is leaving this set to D1 and using the drive externally as DF1:..A project for another day
