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.
Don't miss the rare Texas Instruments 1265 manufactured for Koh-I-Noor Hardtmuth.
