I have a copy of Diab and MQX that would run on it if you have the full 
docs.  the 68332 was a nice micro
that was used in several projects I worked on.  The first one I used an 
ice box that was a crude affair
done by an operation in Massachusetts, which allowed in circuit testing 
via on chip facilities.

Their development compiler was essentially GCC with a chip startup to 
set up the rom, ram etc. registers,
then transfer control to the first instruction of main().

Diab is much like that with a cc setup that prepares the processor, but 
the MQX goes and runs much like
your OS sounds.  it is initially fixed number of tasks, but can add 
tasks, etc.  Not really a timeshare type
system, but a pretty powerful embedded OS of course.

I have several boxes with the 68332 and will have to see if your gizmo 
would come up and run on it.  I'd
need to figure out how to get either an ethernet stack (there are some 
out there), or something to
get to a serial mux from our hardware though.  I think we have 2mb, and 
1mb rom though.  Also a
very nice ASIC which was the reason for the hardware.

Nice project
