According to the manual, my Sharp EL-5500II pocket computer has a
CMOS microprocessor, 40K of ROM, and roughly 4K of user-accessible RAM.
I found three undocumented functions that access absolute addresses:
PEEK, POKE, and CALL.  I know what PEEK and POKE do.  I think CALL
makes it jump to a given address and start executing machine code
there, but I can't use it until I know the processor instruction
set.  I don't even know the name of the microprocessor.

Can anybody tell me (or help me find out) what the instruction set
is for the microprocessor in the Sharp EL-5500II, or at least identify
it?  Is there any chance of getting a map of ROM?
