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.
