The
TI-2200 Checkwriter keeps the balance of three different accounts. The idea
behind this calculator traces back to the TI-1880
Checkwriter.
The Checkwriter was a very successful product and the line was continued with the TI-2200 II Checkwriter, the TI-2200 II and the TI-2200 Plus.
A similar product was sold both from Canon with the Checkbook,
the National Semiconductor NS-103
A, Olivetti Chequebook,
the Radio Shack EC-430 and a
lot others. All used the same calculator chip developed by NEC, Japan.
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.
