In my day, slide rules were it. As I mentioned
previously,
when I was in high school, the SAT and other standardized
tests prohibited slide rules (and nobody that I knew had a
Kurta), but they ENCOURAGED bringing in scrap paper, including
graph paper! AFter my generation folded log graph paper to make
impromptu slide rules, they changed the rules.
I heard about that, but never needed it since slide rules were allowed.
But prices came down! In the mid 1970s, I had
calculators,
and kept buying more as the prices fell. I remember the
FIRST <$5 Commodore! calculator.
I have a SHARP ELSIMATE EL-230 which I seem to remember
cost about $ 5. It must have been in the 1980s. IT STILL WORKS.
I can't see that the screen is also a solar panel - is there another
explanation?
