Which brings up one of the 'bones' that I have
to pick with IBM [as if
they were interested in listening to me. ;-(]
RS-232, was a well accepted 'Standard'. Any time that you saw a piece of
equipment with a DB-25 connector on it, it was almost certainly a RS-232
connection. Then along comes 'Big Brother' (IBM) wanting to save a few
pennies on 'printer connectors' (The Amphenol must have been _way_ more
expensieve. But all the printer manufacturers still seem to be able to
be able to afford it.)
Which brings us to todays state of affairs!
DB-25's that might be either a serial port, or maybe a parallel port, or
maybe something else.
Yes, the time you see (and smell) the result of a Radio Shack Daisy
Wheel Printer II (something I thought was unkillable) plugged into the
DB-25 video connector (carrying power) of an AT&T (Olivetti) 6300, you
want vendors to use better labels. (The aroma of doped silicon being
turned into silicon dioxide [sand] is pungeant, and you never know
which of the evaporating materials will later be discovered to be a
virulent carcinogen -- during a democrat administration, probably all
of them, including a few that were never near the computer.]

They say that politics makes strange bedfellows.
Of course, the main reason they cuddle up is to screw somebody else.
