Ruud,

Just a heads-up :

IIRC without a video card installed you most likely won't even get that far,
but instead will be getting the motherboards boot-error beeps song. :-)

You need a PC that has (at least) one bidirectional LPT port,

Again IIRC, those old 8088 motherboards you are targetting did not have a
bi-directional printer port.  At least, not like the current motherboards
have.    Instead they just had open-collector pins with pull-up resistors
(more-or-less the same to the data pins of a(n Atmel) microcontroller).  You
might want to double-check if the IEEE-488 hardware you want to attach can
handle that.

That ofcourse also means that the software on that website won't work for
those printerports and needs to be rewritten ...

Rudy Wieser
