But peecee-style parallel ports are not x86-specific;
I've got plenty
of SPARCstations with basically-PC-compatible parallel ports.
I built a little adapter (in one of those boxes designed to take a DB
connector at each end) to turn an HP82165 GPIO connector into a PC-like
printer port. I can then use a normal PC printer cable and printer on my
HP71...
In case anyone's interested, here's the wirelist...

Besides, lots of peecees are on-topic by now. (I
even, once, saw a
_really_ nicely built PC-class machine. I think it was one of the
Some of the original IBM machines were fairly solidly made. The 5155
portable will stand up to real use (and some misuse...). Pity the
electronic design was such a joke...
