Plus of course there are some weird designs out there
in D-shells
with a variety of pin sizes - e.g. 13W3 connectors for Sun/SGI video,
and ISTR HP using something similar but with a smaller (DA?) shell
size.
I have a machine somewhere that uses 3W3 - basically, 13W3 without the
ten individual pins, and the shell shrunk correspondingly, to about DA
size (it's at home and I'm not, so I can't be precise about the shell
size).
(Also, weren't some Apollo token ring connectors
something like a 5W2
on an DE-sized shell?)
Could be; I don't know either way, though.
There's some other weird stuff about too which
uses D-type shells
with round pins, but a much smaller form-factor (shell and pin
diameters).
I have a few SBus SCSI/Ethernet cards for which the Ethernet is a funny
connector with a shell that looks about like a DA scaled by 1/2, and
the female connector just has hollow metal cylinders for the pins,
without the plastic fill that most female D-shell connectors have.
(Also, it's possible that pin sex and shell sex are reversed with
respect to one another, as compared to full-size D-shell connectors -
again, they're at home and I'm not.)
