A new member of the family coming soon

I managed to secure an A1200 HD without the HD last night.  Apparently boots okay and has workbench disks, mouse and PSU.  Super excited to pick this up on Saturday.
Also picking up an A500 for $20 that boots okay but has non working keys.  Should be fine for spares if nothing else.  I may get the keyboard sorted and add a Keyrah to make a Pi based Amiga, or buy another De-10nano and use MisTer.  The MisTer cores are really shaping up well with AGA Spec machine running faster than an A4000.

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
