And don't get me started about "DB9"
connectors! 
 Although there can be alternate pinnings, to me THAT means a DB25,
 with pins 1 through 8 and 20. 
 
 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. 
 
I called it "Tramiel bleeds consumers with another lousy proprietary
vertically integrated standard." But that was rather long.
