Hi All...
U-m-m DB-9... Brings back memories from
my sys admin days (early 80s). Built 9
pin serial cables using D-sub connector
with B shell so it could connect to the
standard RS-232 card.
In the early days of computers most
peripheral cards used standard DB25
connectors, even though a lot of pins
were inactive. One of the first things
I'd look at when receiving a piece of
equipment was the manual to see pin out
requirements for the device (badly
written manuals drove me to tech writing
<grin>).
A lot easier to solder only the needed
pins than soldering 25 just to fill up
the shell. This was practice was fairly
standard back then and probably helped
foster the "DB-9" incongruity we face
today..
