37-pin External floppy drive connectors on PC and

Pertec 9-track adapters.
Nit, it has 62 pins. It's a DC62.
There's also a "thicker" 50-pin 3-row
(not HD) connector used for
the external connector for some PC-based QIC-02 and QIC-36
controllers (Wangtek, I think).
That's the D-size. The DD50. There are also DD78 and DD100 connectors.
There were also non-standard sizes, such as the 19-pin
D connector
used for Atari ST ACSI connections.
I've heard them described as DF19 (NeXT monitor, Macintosh floppy)
and DG23 (Amiga floppy, Amiga RGB), though this is not part of the
standard.
Jules mentioned alternate pin designations too. Besides the "W" for
coaxial "pins", there are also "high current" pins, physically the
same size as the coaxial ones but with a single conductor, and
perhaps others besides.
Gee, look what I found.
