basically 486 but have a few extra instructions - probably just cpuid
and (IIRC) rdtsc.
Designed for low power embedded use they won't ever have been suitable
for a desktop - but are probably fast enough for some uses.
I'm not sure how much keeping 486 support actually costs, 386 was a
PITA - but the 486 fixed most of those issues.

Right, we have "last of mohicans" (to date) Intel Quark family of CPUs
(486 core + few i586 features).
This is for the embedded world and probably not for powerful use.

What is the status of PC/104?

I have three GPIO drivers for PC/104 machines and these are for
embedded industrial usecases. I am curious about what CPUs these
beasts run on in practice? Are they getting upgraded?

Paging William, I think he work on these daily.
