Ever hear of PC104?

still too big man still tooooo wayyyy bigg..

you have got to open your mind, tesla old boy!

I've seen (or worked on) PC's or equivalent in applications like
* HVAC control
* manufacturing workstation control
* typesetters
* medical test equipment
(ok, that last one really was a SUN machine, but same idea)

The key point is, as I like to phrase it, that an embedded system
looks like a "whatever" device to the end user. The end user should
not perceive that there is a computer involved. They might be aware
there is a computer used but they do not interact with the device like
they do a PC. That's what makes it embedded, not the size, cost,
realtime constraints, custom peripherals or other contstraints.
