From the description I got the other day, it's
slots 1, 2, and 3 that don't
exist in the PC. Isn't slot 8 the one nearest
the power connector?
So ... slot 8 was a layout error, then? ... or was it just stupidity?

The problem with slot 8 in the PC is that it doesn't exist :-). The PC
only has 5 slots.
More seriously, the IBM PC/XT is the only true-blue IBM PC family machine
to have this 'problem'. All the slots are electrically identical on the
PC. And on the expansion unit. And on the AT and PC/286 (well, there are
some 8-bit only slots and some with the 16 bit extension on both of those
machines, but all the 16 bit slots are the same, and the 8 bit part of
all 8 slots is the same). No problems with one slot being the 'wrong
side' of a buffer.

"SLOT 8" compatible IS NOT ABOUT 8 bit v
16 bit!
"SLOT 8" compatible is whether it will work in an IBM XT (not
compatibles) in slot #8 (the slot closest to the power supply).
In the REAL IBM XT (not necessarily compatibles), that slot is different
from the other 7.
Was this an issue in the PC, or just the PC/XT?
