Intially, there were 4 shell sizes . I'll give the number of pins and the
common usage so you have some idea what I am talking about :
Normal High Density
DA : 15 pin (PC Joystick, Ethernet AUI). 26 pin
DB : 25 pin (RS232, PC parallel port) 44 pin
DC : 37 pin (PC external floppy port) 62 pin (PC expanison chassis)
DD : 50 pin (Sun 3 SCSI)
The other standard one :
DE : 9 pin (PC/AT serial port, MDA etc video) 15 pin (VGA video)
There are also 19 and 23 pin D connectors used on the Atari ST and Amiga.
I've heard of them being called DF19 and DG23, but I am not sure how
official those names are

BTW the B in DB refers to the size shell. The
25 pin connectors used on
the original IBM are B size. Other sizes use a different letter ie DE, etc.
But a lot of people call every size "DB"
So what letters are used for other sizes?
