Unisonic
introduced with this Model LC 7463 in 1982 an "Ultra Thin Alarm Clock Calculator
with Enamel-Like Finish". The specifications look rather familiar to us -
compare this LC 7463 with the TI-1788.
Dismantling
the featured LC 7463 manufactured in March 1982 by an unknown
OEM (Original Equipment Manufacturer) in Taiwan reveals a clean design
centered around a NEC uPD1032G single-chip calculator circuit soldered on a
double-sided printed circuit board (PCB) and powered by two small LR43 batteries.
Inspecting the PCB of this Unisonic LC
7463 calculator brought our attention to a small mark reading CC-50,
we spotted a similar PCB-Mark already with the TI-1788 reading
CC-31 B and started compiling a list
of the PCB-Marks on calculators
manufactured by OEMs for Texas Instruments.
