More drives for the project

...
   Apple PC 5.25
Drive (DC-37) - was this for connecting to a PC or a special
 card in the Mac? 
I think the latter, to allow a Mac to read/write PC disks. I have an 
Apple book on designing add-on cards for the Mac, and one of the design 
examples is the PC-compatible disk controller. It uses a 765 chip in the 
obvious way.

I am not sure if that card was ever a commerical product, but something 
similar might have been,

I think the drive is just a standard PC disk drive in an Apple case. 
The drive came in two flavors. In both cases, the drive was the same, the 
change was the controller card. One version came with an SE PDS 
controller card, the other came with a NuBus controller card.

In either case, the card works ONLY with either the SE (800k or FDHD), or 
the Mac II, no other NuBus Macs.

You need the card to control the floppy drive, but I believe you are 
correct, it is just a standard PC drive in an Apple case.

I have one with the SE card.

There were also 3rd party PC drives that hooked up to the standard Disk 
Drive port on all the early macs, but I don't think Apple ever made one 
like that.
