The Canola F-11 statistical desktop calculator was the most sophisticated calculator developed by Canon. It is very similar to the earlier Canon F-10 but added some extra memories and the statistical functions.
The calculator architecture was developed by Hitachi but seems to be very similar to the successful TMC0501 family introduced by Texas Instruments with the SR-50. Instead the single-chip calculator chips found inside the F-5 and F-6 models you'll find a processing chip HD3650 surrounded by five ROM (Read Only Memory) and one RAM (Data Register) chips. The pocket sized Palmtronic F-7 and FC-80 used the same processing chip with less ROM and RAM chips.
The display module is very similar to the later Panaplex™ manufactured by Burroughs found in the TI desktop calculators.
In addition to the usual scientific functions of such a calculator the F-11 added 10 memory registers, 7 conversion functions and two-dimensional statistics. Finally, if you don't need the statistical functions you can use another 5 registers for your calculations.
The housing was developed from the Canola L121F and used two years later again with the Canola L1632.
