Non-Programmable-Operations::

CAT 1-6		catalogs: 1) user programs, 2) external functions,
		3) built-in functions, 4) EMDIR, 5) ALMCAT, 6) user keyboard

Notes::

Same as a -41C but with four memory modules, a Time Module, an
Extended Functions / Extended Memory Module, and assorted
miscellaneous functions built in.

"Halfnut" is the code name for a  redesigned version of the -41C
internals. Externally and functionally it is identical to the other
machines. It was so called because the processor board was only half
the size of the original design.
