Can you give an estimate of the price for all the parts?

Good idea.  Will the microcontroller also allow the amount of data being
sent over the link be minimized?  So it would only take a small instruction
to get the info  so that the amount of data being sent through the link is
minimized and the microcontroller could take some of the processor load off
the z80 on the calc.
