IN my case, all of my drives are terminated in DC37M connectors and my
controllers have DC37F.    Half-height and 3.5" drives are housed in old
IBM 4569 boxes (we bought 50 of the things back in the day) and the 8"
and FH 5.25" have their own external boxes with PSU.

So, no matter what I want to do, it's a matter of plugging something in
and turning it on.  Need a 100 tpi drive?  Just grab it off the shelf
and plug it in.

That extents to not only PC floppy controllers, but things such as
Catweasels (I fit them with a buffer board ending in a DC37F on a
bracket) and even my WD-based controllers and my MCU setups.

It streamlines the process greatly.
