HP-16C Computer Scientist OWNER’S HANDBOOK

Complement Modes and Unsigned Mode (p.29)
Quote:The HP-16C provides three conventions for representing numbers: 1's Complement mode, 2’s Complement mode, and Unsigned mode.
The 2’s Complement mode is the default mode when the calculator is first turned on or after Continuous Memory is reset.
Once a mode is set, it remains in effect until you change it or until Continuous Memory is reset.
(All examples in this handbook use 2’s Complement unless otherwise indicated.)

Interesting, I obviously had the false impression here...
But considering that the complement mode is also saved in memory even with the calculator off, isn't this bit of a moot point? Once changed it'll remain as selected.

Maybe it's an easy change to set an initial default to CMP2, I'll take a look at that part of the code.
