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 the standard TI-1001 with brown-silver coloured housing.
About two years later an enhanced Checkwriter was introduced
with the TI-2200 Checkwriter.
The TI-1880 Checkwriter was not the only approach to combine a already known calculator with some usefull 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 shut off but uses power-hungry electronics.
