Toshiba
started already in 1972 the production of portable calculators with the BC-0801.
Later products like the BC-0808B reduced the size
and the weights dramatically but today we would still call it huge. This BC-602L
was introduced in 1974 and marked another important step in shrinking the
electronics of a calculator.
A
deeper look into the BC-602L reveals easily the secret how engineers created
such a narrow calculator. The display was reduced to only 6 digits instead the
usual 8 digits. Nevertheless the BC-602L is capable of calculations with results
of 10 digits. The small [<>]-key swaps the upper and lower
halves of the result.
Don't miss the BC-602L sporting a grey housing and
the BC-603L with a [SQR]-key.
