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 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.
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
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:
|L100||1971||10||TMC1737, TMC1753, TMC1754, TMC1807|
|L100S||1972||10||TMS0106 single chip|
The next desktop calculator in Canon's line was the L100A using the TMC1824, TMC1825 chip's of the LE-10.
