You all may think that I'm nuts, but I've kinda had a pipe dream for a while
about putting a basic 32 bit CPU in the RCX enclosure. Something like a
Motorola 68k or ColdFire. Lots and lots of tools out there for 32 bit micros!
Heck, if money were no issue, a person could even put a Java VM on it. But
I'm getting carried away...

My biggest problem has always been that I have only a basic knowledge of how
to build even simple circuits. Software is definitely my specialty. Building
a CPU board looks fun, but something that has a learning curve to it. Such a
small board would most likely have multiple layers, maybe even parts on both
sides of the board. A soldering iron doesn't help much there.

So an even bigger problem is once I get a successful design on a breadboard
with schematics and all, where can I go to find a company or person who can
actually build a pc board for fairly cheap??  I could be wrong, but building
a CPU board that will fit into the Lego enclosure looks like it could get
quite expensive. And that's if I could even find a place that would be
willing to build just 1 or 2 boards at any price. I like the RCX and all, but
I don't think my marriage can afford to fund such a major cost to simply be
able to build a powerful 32 bit Lego robot :-) Reality is such a pain to deal
with! :-)

The HC11 is a really neat idea as well. And most likely the most practical.
