I have a thing in the pipeline where a Coldfire board that went
obsolete years ago is being ported to an ARM based on a RasPi 3. I've
built a HAL for it and am running, more or less, the original code[1]
on the HAL. The HAL mocks memory-mapped peripherals on the obsolete
hardware.

[1] which used an ancient extension of 'C'.

The first prototype will be an actual RasPi 3 with USB peripherals.

But even more than that, I am developing a rather slavish devotion to
building plant simulators using small $50 ARM boards and USB
peripherals.

Some of the USB peripherals are Ardiunos.

It is simply the right thing to do these days. The simulator will
diverge from the actual plant, but if you do this right, you can fold
the error signals into the  plant model iteratively until they match
well enough.

There is one cultural problem - many people irrationally believe their 
system needs much lower latency than it actually does.
