I don't remember if I was aware of this at that
time, but it is very
likely and that could have been the inspiration for our project.
In the RiscPC era they used actual Intel processors
instead of (or was
it as an alternative to) software emulation.
Instead of. There were third-part hardware addons using Intel CPUs by
1989 or thereabouts.

Many people think Intel was stupid to have the 80186
be incompatible
with the PC but they forget that this processor was practically finished
by the time the PC came out and was launched just a few months later,
And it was evidently really meant for embedded applications rather than
as a CPU for IBM-compatible PCs.
