People have successfully modeled some of the processors using current
technology such as FPGA's. What if someone used and FPGA or similar and
produced a processor capable of running the instruction set of a specific
machine, but was compatible at the PIN (and other HW considerations) of a
x86. A standard motherboard (obviously with a completely vustom BIOS) and
standard hardware could then be used.
Depending on what type of HAL was implemented their might be the need for
some custom drivers at the emulated OS level. But this would provide a
platform that used current hardware (easy, available, cheap) without any
additional layers....
As I said, I thought I was completly wacko when the idea first came up, but
I wanted to get the lists thoughts....
You may as well design it as a co-processor card that goes into the PC and
then takes over the bus. Sure, it's probable that it can be done the way
you describe, but the distance between "probable" and "possible" is
measured in terms of sanity.
