AFAIK, the 19, 21, and 23 pin D-sub connectors don't use standard shell
sizes, so they probably don't have an official Dx prefix.

Apple used the 19 D-sub for their external floppy connectors, vs. the 20-pin
dual row header used for internal connectors. Except the Apple III, which
IIRC used a 26-pin dual-row header for their *external* floppy connector.
I think that was changed on the Apple III+.

The Amiga used a 23-pin D-sub for their external floppy connector.

I saw a 21-pin D-sub on something, but now I've forgotten what.
