Diskdrives are getting more & more scare to find. Specialy drives that can be made compatible with the MSX.
Here’s a howto for making a new revision of the Mitsumi D359M3 compatible with the MSX.
Setting the drive to DS0:
Cut the trace from the IC to pin 12
Solder a wire from the cutted trace (on the IC side) to pin 12 (brown wire)
Put Disk Change on pin 2:
Make a solderjumper on DEN2
Put READY on pin 34:
Cut the trace from pin 34
Solder a wire from pin 34 to the 2nd pin from the right of the flatcable (white wire)
Now the drive can be used in your MSX (or in your Amiga or Korg or Yamaha)
