Brand: CASIO
Model: H-816 Memory B-1
Type: Calculator
Picture: CASIO H-816 Memory B-1
Batteries: AA x 2
Lifetime: Introduced: ca. 1974
Terminated: unknown
Notes: Nice plain calculator with memory, square roots, percentages and the ability to set the display to two-decimal currency mode, either truncated ("CUT") or rounded ("5/4").

There's no display indicator to show that a non-zero number is stored in its memory.

Talking about zeroes: this calculator has negative zeroes. When you calculate "2" "÷" "3" "×" "3" "-" "2" "=" the display will show -0.


A power adapter.
