The Canon Canola L100S was introduced together with the first desktop calculator manufactured by Texas Instruments - the TI-3000

L100S_DISP.jpg (30796 Byte)The display found in the L100S is similar to the Panaplex style found in the early desktop calculators manufactured by Texas Instruments.
L100S_DISP2.jpg (52380 Byte)The Hitachi display module uses white ceramics instead the glass construction of the
Panaplex™ manufactured by Burroughs.

L100S_ic.jpg (15442 Byte)The L100S was the first Canon desktop calculator using the TMS0106 single-chip calculator chip. Within roughly 12 month the brain of a desktop calculator was reduced from four (L100) chips to two (L100A) chips and now to a single chip.

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



Within some month the L800 used again a single-chip design fitting in a smaller housing. The Canola LS-1 looks similiar to the L100S, we don't know which one appeared earlier on the market.

Other calculators using the single-chip calculator technology introduced by Texas Instruments were the Heathkit IC-2008 and Toshiba BC-0802.

Compare this strong calculator with the later Canola L813
