Canon Palmtronic LC-5 Awarded the Good Design Award in 1978 Released in February 1978 Broke the 4mm barrier, debuting at 3.9mm ◎ Power on and function confirmed OK I have several calculators from the cleanup of a store I used to run, and I believe these are almost new, unused items left over from sales. They are very clean considering their age. ※ Leather case and instruction manual are not included. ※ The original batteries are old and cannot be used. Please enjoy them as a collection piece. ************** Excerpts from the internet below LC-5 (Silver type) A 3.9mm thick calculator released in February 1978. It used flat lithium batteries instead of the conventional button-type oxide batteries, and employed a 0.1mm thick polyimide resin for the printed circuit board, and a 0.3mm thick LCD, allowing it to break the 4mm barrier. Uses CMOS-LSI. One lithium battery could be used for about 2,000 hours. Good Design Award-winning calculator. 68(W) x 115(D) x 3.9(H)mm. 50.5g (including battery). 6,800 yen. CR2430 can be used as a compatible battery. I used a new battery for confirmation, so I will include it. #Canon #Canon #CanonCalculator #OldCalculator #NotebookTypeCalculator #ShowaRetro
