TC83220-0009: Single-Chip CMOS LSI for FL (fluorescent) Calculator with Printers
The TOSHIBA printing/display calculator circuit
TC83220-0009 is 10/12-digit calculator on a single-chip CMOS
LSI.
TC83220-0009 can drive the printing machine (M-42TV/42V;
EPSON) with magnet driver circuit, and can drive the fluorescent
display tube with DC-DC converter. It contains a 4 K-word ROM,
a 256 × 4-bit RAM.
