Canon
entered with the Palmtronic LC already in 1976 the market of LCD calculators and
was about 6 month ahead the first Texas Instruments TI-1750.
This
Palmtronic LC-5 uses once again a front access to the battery, we know this
unique feature already from the LE-83 introduced in 1974.
Nevertheless is the access to the battery difficult, two screws have to be
removed first. Later calculators like the LC-6 and its
sibling LC-61T corrected this flaw.
The
printed circuit board (PCB) of the Palmtronic LC-5 makes use of the Toshiba
T3707 single-chip calculator circuit.
The Palmtronic LC-5 was available with a black housing, too. View it here.
Don't miss the LC-4 introduced in the same year with two standard batteries instead the CR2025 lithium battery.
This
LC-5 was donated by Mark Diflumeri. Thanks !
