Sounds like it - similar backgrounds from different experiences... kewl.

This is one of the bigger differences - when it comes to PC104, I'll be the
first to admit I'm a hobbyist.  I've experimented with them, and while they
are more expensive and more custom than a generic serial card, they sure
are small.  Plus, I didn't have to build a switching power supply to create
the negative supply lines (Oh Bob, still waiting for that schematic <Grin>).

Absolutely agree.

Good point - you're following he keep it simple stupid theory - certainly
been proven to be a good one.

Well, you are still leaving me with one valid argument - its familiar
technology for the masses, and one who knows a high level language like
what they use at work, could use the PC to make it happen.

Oh, and I never said it was the solution to every problem, just potentially
the solution for mine :)  Though I am almost completed a 68HC -based ecm
design.
