I may have my terms wrong. If so, sorry about that. What is important
is that in very old PCs of the 8086/8088 vintage, there are two
different slot widths. There are also proprietory power supply
connectors to the motherboard that crop up at a number of levels after
that. When buying a case to build in, one should always open the case
to check out those two situations or he could end up with wasted
expense.
My first PC was a locally built clone XT (with both 8 bit and 16 bit bus
slots. The 286 motherboard that I upgraded to wouldn't fit either the
motherboard mounts or the slot widths. From that point on my
understanding was that XT=8088 and AT=8086,80286,80386, etc., and that
AT became the standard for slot width. A Daiwo XT and an IBM PC (the
original PC) gave me the same problems as my orginal XT. I always
thought that the difference was between 8088 and 8086, and that the 8086
was not an XT. I have been wrong before, and I may be wrong here. If
so once again, sorry about that. What is important is that there is an
incompatable difference between some older cases and upgrade parts. By
the way the XT keyboard will not work on an AT either, although some
keyboards can be switched between XT and AT and so made to work with
either one.
