The
Toshiba BC-819 started a design line with black, blue and red keys continued
with the BC-8111B and BC-8112SR
till 1979.
From
a technical point of view the BC-819 is a typical Toshiba product centered
around the T3393 single-chip calculator circuit and a huge discrete DC-DC
convertor.
This Toshiba BC-819 introduced in 1976 marks the border between the vacuum
fluorescent display (VFD) and liquid crystal display (LCD) technology. While the
BC-819 uses the Toshiba T3393 calculator circuit, was the T3394 chip used in the
LC-810 - Toshiba's entry into the market of calculators
with LC-Displays.
