Well, I would not venture to suggest just where it originated, but the
37-pin D-sub connector has pretty much (there have been exceptions) been
the standard for connecting external floppy drives of all sizes. Almost
all PC (ISA) FDCs that support external drives use it, and the Xerox 820
(CP/M) series used it. Most S-100 crates did not, as they typically ran
the ribbon cable direct from the card to the drive.

What I find odd about the MITS FDD is that they used a

found one among a set of enclosures I bought about 20 years ago. While
this is already promised out (once I find the top of the box), I do know
that there's an ALTAIR hard disk controller box, apparently with a drive
inside, judging from the weight, at Gateway Electronics in Denver, (303)
458-5444, if anyone's interested. It's the same size as the ALTAIR FDD
box.

Well heres where I stand on it. Never seen one, I was there, and never
seen an advert for one, I have back issues. Was it possible, sure. The
8"
design with some tweeks would certainly do
minifloppy.
