LC-81M_IC.jpg (39453 Byte)The Canon Palmtronic LC-81M replaced in 1979 the original LC-8M and uses still the Toshiba T3709 calculator chip and a yellow LCD. Within one year this chip was obsolete and Canon introduced the LC-82M.

In 1985 Canon introduced with the LC-83M a four-banger with the Algebraic Operating System (AOS) in a much thinner housing.
