The Canon Canola L100 preceded the first desktop calculator manufactured by Texas Instruments - the TI-3000 - about one and a half year.
Instead of the later single-chip calculator electronics found in the TI-3000 and its sibling TI-3500 the L100 uses four chips similar to the Pocketronic. A similar architecture could be found in the even larger desktop calculators L121 and L160, too.

The display consists of 10 single tubes with a 7-segment layout. Later products like the L100A or L100S used a construction similar to the Panaplex™ display manufactured by Burroughs.

In Texas Instrument's history of calculator chips the L100 plays an important role. It adds to the three LSI-circuits (Arithmetic Chip, Entry Chip, and Data Chip) of the Pocketronic an additional Display Chip.

Please compare the quick evolution of the calculator technology:

Type	Year	Digits	Chip set
L100	1971	10	TMC1737, TMC1753, TMC1754, TMC1807
L100A	1971	10	TMS1824, TMS1825
L100S	1972	10	TMS0106 single chip
L121F	1972	12	TMS0201, TMS0302

The next desktop calculator in Canon's line was the L100A using the TMC1824, TMC1825 chips of the LE-10.
