The PC has been through a lot of change over the years. Remember the
original machine had an 8088 (8 bit bus) limited memory and an
interrupt system out of the Intel handbook. After this was cloned then
we got the AT line of computer with ISA cards with 286's and 386's. Now
with the Pentium class machines with PCI and better bus connectors, new
and different northbound/southbound controllers I can say with certanty
these machines are NOT the original IBM PC. The architecture is widely
different. Also having programmed 8086's and 80186's, now with full 32
bit registers everywhere and no segmented address space while backwards
compatible to an extent these are very different processors.
