The Canon Checkbook III "Money Manager" continued the idea of an Account Manager introduced already in with the Checkbook and continued with the beautiful Checkbook II.

It is very similar to the Texas Instruments TI-2200 II Checkwriter.

Dismantling this Checkbook calculator manufactured in Thailand reveals a very solid construction centered around a NEC uPD1833G singlechip calculator circuit.

In 2003 this Checkbook III was still available in the stores.
