LC-830_IC.jpg (42676 Byte)This 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.

LC-830_BAT.jpg (22053 Byte)Most original Toshiba designs use a neat battery holder that accomodates 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.
