The Canon Canola L100 preceded the first desktop calculator manufactured by Texas Instruments - the TI-3000 - about one and a half year.

single-chip calculator electronics found in the TI-3000 and its sibbling 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.

In Texas Instrument's history of calculator chips the L100 plays an important role. It adds to the three LSI-circuits (Arithmetic-, Entry- and Data-chip) of the
Pocketronic a forth chip to manage the display.  
Please compare the quick evolution of the calculator technolgy:

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 chip's of the LE-10.
