Toshiba LC-827 replaced the earlier LC-825. The
appearance of the two calculators is very similar, main difference in the
combination of an [ON] and [OFF]-key instead the sliding switch.
Dismantling this Toshiba LC-827 calculator manufactured around July 1980 in Hong Kong reveals a uPD1832G single-chip calculator circuit manufactured by Japanese company NEC instead the usual Toshiba chips. The uPD1832G is a stripped down variation of the uPD1833G located in Account Manager calculators like the National Semiconductor NS 103A or Texas Instruments TI-2200.
