Checkwriter_1.jpg (92367 Byte)The TI-1880 Checkwriter combines a wallet to hold the checks, balance book, cash, credit cards and a pen with a slimline calculator. The calculator is a standard TI-1001 with brown-silver colored housing. 

About two years later an enhanced Checkwriter was introduced with the TI-2200 Checkwriter sporting Account Manager functionality.

Dismantling the featured TI-1880 Checkwriter manufactured in March 1982 by Texas Instruments in their Abilene, Texas facility reveals a well known design based on the TP0311 calculator chip.

The TI-1880 Checkwriter was not the only approach to combine a already known calculator with some useful accessories. Don't miss the TI-1040A Tax Pak and the TI-1850 Visor Kit. 

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