  It's a pity that a lot of the custom uProcessors
were never really
 publicly documented. That includes the ones found in the Sharp Basic
 calculators. 
Some of the Sharp ones were documented - There are Technical reference/machine
language manuals for (at least) the PC1500 and PC1350 families - I have
both of them. Sharp service manuals (yes, they exist as well) contain
schematics/pinouts but little (if any) machine code information.
