The Canon Canola LS-1 and Canola L100S are almost identical. Unfortunately we don't know which of the two calculators was introduced earlier. Probably the LS-1 was later.

LS1_PCB.jpg (77892 Byte)The internal construction of the LS-1 is typical for the early Canola calculators and uses a small metal chassis securing the transformer and printed circuit board. The keyboard and display are attached with robust connectors. The main electronics is centered around the TMS0106 single-chip calculator circuit. The display module is very similar to the later Panaplex™ manufactured by Burroughs found in the TI desktop calculators. The high-voltage drivers needed in this design reside in the black modules (6248 for the digits and 6249 for the segments) between the calculating circuits and the display.

LS1_KBD.jpg (45736 Byte)The keyboard construction is very rigid and uses small Reed-contacts excited by small magnets attached to each key. Even today, after more than 30 years of usage the keyboard operates smooth and reliable.
