The D-sub letter-shell-size thing is incomplete. What
do you call a
19 pin D-sub? They're typically referred to as a "DB-19", but the
shell is smaller than a DB and larger than a DA. These were used,
for example, on Atari ST ACSI connections.
And for external floppy connectors. Apple used the 19 position, and the
Amiga used the even less common 23-position. I've seen references to 17
and 21 position, but don't know of any common applications. I don't
think there was a letter designation for those shell sizes.
