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.
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.
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.
