In the U.S. at least, IBM NEVER had a joystick.
Did they
ever sell one for the PC-jr? That machine had a 2 row header
plug for the joystick port, and it's not totally trivial to get a socket
that will fit it....
IIRC the PC-jr joystick interface is identical electrically to the PC
one, so the same joystick mechanism would work with both machines. Maybe
that's the one IBM showed in the PC O&A TechRef.
1) I have never seen a joystick for the jr that had ANY resemblance in
appearance to it.
2) The TechRef in question was from 1981 (the original release of the PC
5150), LONG before the jr was even imagined.
I'm assuming that the drawing was intended to be a generic picture of a
joystick ("to be purchased after-market"), and that their artist simply
happened to use the RS one as a sample.
