I understand.  But adding the footprints does not mean they need to be
populated.  The board I have here is only about 4" on a side and
single sided with all the functionality I described including
Ethernet.  Adding USB or some other IO would not take a lot more space
and the board can be made smaller by putting parts on the bottom.  You
can see a picture at the
http://photos.groups.yahoo.com/group/OKI-ARM-mcus photo page.  Then
the board can be much more widely used and populated according to the
needs.

I'll give that a try.  Did you send an email or call by phone? What
address or number?

The OKI part comes in a 144 pin BGA, 11 mm sq., 0.8 mm pitch.

Like I said above, you can put hardware on the board and not populate
the chips.  Also, you don't need an OS really.  I found out that there
is a microMonitor that provides debug support and hooks for using IO
like the serial port and Ethernet.  It is from Lucent and it is open
source.  I am no SW weenie, but it looks pretty easy to port.  It is
running on this OKI board.

Don't you need some hardware for Robotics?  Aren't you going to have
an FPGA or CPLD on board?
