Hmmmmm... I wonder what my little Sinclair Cambridge Scientific
calculator is worth???
I does a lot of scientific-related calcs, over and above the usual
operations... sqrt, sin, cos, tan, exp, etc.
This one was had from Boots The Chemist limited, 1-2-3 Marble
Arch., London W.I. on 25 Apr 1977, for UKP 8.45, .43tx, 8.88 tot.
It works well, and comes in a little plastic clamshell case... in
which case the Instruction Booklet (English/Deutsch/Francais) does
not quite fit... interesting.
Maybe I'm a millionaire.......
