Yes, I agree it is probably a lost cause these days. We might as well
leave that letter off and call them D9M or D9F and HD15M or HD15F.
There never were official letters for the D19 or D21 parts that I know of.

I would not use a Radio Shack catalog as a definitive reference...

Try http://www.dsubconnector.com/ and look in the Technical Data Sheets
section. Now I know the number of pins all 10 standard sizes have:

shell	SD	HD
E	9	15
A	15	26
B	25	44
C	37	62
D	50	78

Interesting piece of info I found on that site - standard D-Sub connectors
are only rated for 100-200 mating cycles. As an option you can get 500
cycle variants.

My other pet peeves are processors listed as having clock speeds in mHz
(milli Hertz) and RAM access times in mS (milli Siemens) :-).
