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

LC-5_2.jpg (49221 Byte)LC-5_1.jpg (72430 Byte)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 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.
