Introduced: 1979? Terminated: unknown |
Notes: |
I'm not sure whether the manufacturer is indeed "HD" because I can't
find any references to that brand name as a calculator manufacturer on
the Internet. Still, this calculator as a spectacular type designation:
"Executive 2200 S 79/80".
The calculator itself is a plain calculator with added functions for squares, square roots and reciprocals. It also has constant memory. |
