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.
