This
Canon LC-25H is a very basic calculator introduced in 1990. It was manufactured
by Nam
Tai Electronics, Inc. in China and basically it resembles the TI-1105
introduced in the same time frame.
Disassembling
the LC-25H reveals indeed a well known design using a single-chip calculator
circuit wire-bonded direct on the printed circuit board (PCB).
Don't miss the LC-23, LC-28H III and the LC-210L.
