This
Toshiba LC-110PV is a remarkable calculator. It seems to be the first battery
operated printing calculator using normal paper. You should compare it with the TI-5025
introduced about one year earlier but using thermal paper for its printout.
The
internal construction of the LC-110PV is centered around a Toshiba T3781, the
first single-chip calculator circuit supporting impact printers. Additional
driver circuits TD62302 contain power transistors and level shifters for the
printer interface.
The
huge impact printer used in the LC-110PV sports a famous name, it is a EPSON Model-710.
The successor of the LC-110PV could be found with the LC-1028PV,
actually a twin of the TI-5010.
