The TI-1400 differed slightly from the TI-1200 introduced roughly one year earlier. The brown housing together with the valuable keyplate design made this calculator desirable for the manager desk.

Under the hood the TI-1400 was identical with the TI-1200, one additional key gave access to the previously hidden Change-Sign function. Don't miss the similar TI-1450.

Both the calculator shopping game Check Out and the fun-with-number game Calculator Squares included the TI-1400.
