I hadn't though of those, but it should be easy.  

My plan is to work up a program that has an initial suggestion for
buttons, an initial screen support, and can do limited calculation and
graphing to give people an idea what I'm talking about.  Then I can
see who would be interested in continueing.  I don't plan to finish
all the math work at this point.

I gather that designing the hardware will be pretty easy for someone
who knows what they are doing.  The part that I'm not really familiar
with will be what it will take to get a basic scheme running on the
calculator well enough to move the code from the software prototype
over.  I think it might be best to write a memory manager in scheme,
and it would be nice to have an on calculator debugger I think.  Also,
I want to make sure it is actually a good scheme.  For instance, it
should allow deep recursion without fear of a stack over flow like
good unix schemes will.

What are you looking for exactly in the way of logical operations
anyway?  Just or and xor not as functions to call in the calculator?
