Are you suggesting I like unlabelled ports? Because I
can assure
everybody that I much prefer proper labelling...
No, I was rather referring to those who make fun of people with labelled
ports.

And the mouse signals on the HP-HIL cable are not
quadrature ones either.
Exactly. It's a serial bus. You can't get farther from quadrature.
It's not as if the adapter takes the PS2 protocol,
undoes the damage, and
gives you the quadrature signals back again.
No, that sounds overtly involved.

You said 'trial and error', which I took to
mean something like 'Oh look,
this cable fits that (RS232) port at one end and the back of the printer
at the other. Let's use it for that'. Exit magic smoke...
Well, if ports aren't labelled, there is no real way to find out.
It's all very simple if you've only every operated within the IBM PC context
within the last three years or so, but we established in the last thread that
there were a lot of devices which would let out magic smoke if connected to
your PC just on the basis of form factors.
