An XT doesn't give a damn what goes where as long
as it physically
and electrically fits. And proper use of a chainsaw on the case
minimizes problems with things fitting physically.
ALMOST.
The slot closest to the power supply on real IBM XTs is actually slightly
different than the other seven! REALLY! Check the schematics! I think
that IBM might have originally intended it for use with a coprocessor board?
I order to prevent anyone from using it for anything else; and because
multifunction boards had virtually eliminated demand for single funtion
cards that IBM had excess of, IBM provided a "free" serial card already
installed in that last slot.
