My main reason for wanting to get an IBM type drive is to read my old
COCO floppies directly on my COCO2.  And since I cannot currently
locate a COCO Floppy, I figured if someone had gotten an IBM drive
working on a COCO I could do this.  All of my floppies were used under
Disk Extended Color Basic.

In the title Block all it says is Project 523.  It does not use 12
volts, and it hand written under the date is Color Computer II Disk
Controller.  I would assume it is the FD-501.  It has the 1793 Floppy
controller chip.
