Making a ALPS DF354H127F MSX Compatible

Here’s a howto for making a ALPSDF354H127F compatible with the MSX.

First cut the traces of Pin 2 & Pin 34 (I use a 2mm drill on point A & B in the picture)

Setting the drive to DS0:
Change the solder jumper from DS1 to DS0

Put Disk Change on pin 2 (Not necessary for some Philips Models)
Solder a wire from pin5 of the controller IC to Pin 2 of the connector. (Red Arrow)

Put READY on pin 34:
Solder a wire from pin 32 of the controller IC to Pin 34 of the connector (Blue Wire)
