Toshiba LC-830 followed the LC-821 and defined already in the year 1978 the standard design of a simple
LCD calculator. It uses the Toshiba T3709 calculator chip located already in
dozens of "basic" calculators like the TI-1750,
the Radio Shack EC-264,
and the Canon LC-8M.
Most original Toshiba designs use a neat battery holder that accommodates two coin-shaped batteries. Find it with the LC-834WA, too.
Later Toshiba calculators like the LC-844WA used a simpler construction to hold the batteries.
Don't miss the odd LC-842 and the later HB-102.
Toshiba introduced with the LC-831W the first combination of a calculator and clock with two discrete LC-Displays.
