Texas Instruments entered the market of Checkbook Calculators with the TI-1880 Checkwriter in 1981, almost 3 years after National Instruments' NS103, but it was nothing else than a basic calculator put in a fancy wallet. The TI-2200 Checkwriter introduced in October 1982 added Account Manager functionality with three permanent (till you remove the batteries) Memories and started a very successful product line. We discovered as of now seven different family members:

1982 - 1984: TI-2200 Silver, unknown OEM, Americas market
1982 - 1984: TI-2200 Silver, unknown OEM, European market
1984 - 1986: TI-2200 Gold, Compal Electronics Taiwan, Americas market
1984 - 1986: TI-2200 II Gold, Compal Electronics Taiwan, European market
1986 - 1991: TI-2200 II Solar cells, Compal Electronics Taiwan, Global market
1991 - 1996: TI-2200 II Solar cells, Compal Electronics Thailand, Global market
1996 - 2002: This TI-2200+, Inventec Corporation Malaysia, Global market

Dismantling the featured TI-2200+ manufactured in July 1996 by Inventec Corporation in Malaysia reveals a clean design centered around a Toshiba T7752S single-chip calculator circuit soldered on a double-sided printed circuit board (PCB) and powered by a small LR43 battery.

A similar product was sold from Canon with the Checkbook III at least till 2003.

Don't miss the Corvus CheckMaster introduced by Mostek already in 1975. This rare product retains the balance of your memory even when shut off but uses power-hungry electronics.
