You need to tell that to my motherboard. ISA boards run just fine in
slot connectors (I know, I do it). The pin spacing is different in
that there are double the number of pins and they are spaced
vertically one above another. I don't know all the tech details,
but ISA boards simply make
contact with only their required signals and do not interfere with the
bus signals for EISA control.
The trick is that EISA and ISA are completely different, howevery through
an engineering trick they managed to put the two conectors in the same place
in such a way that there wouldn't be a motherboard realestate penalty for
having both busses.
