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 Checkwriter (2nd design), the TI-2200 II and the TI-2200+.

Similar products were available with Canon's Checkbook, National Semiconductor's NS-103 A, Olivetti's Chequebook, the Radio Shack EC-430 and a lot others. All used the same calculator chip developed by NEC, Japan.
