TI-1200-Lady_Back.jpg (217097 Byte)This colorful calculator gives you an idea of marketing. The only changes compared to the basic TI-1200 were the blue-yellow keyplate and a off-white housing. With this calculator Texas Instruments targeted a total new market - the hand-bag of modern women. A second attempt was made 13 years later again with the Nuance. The new color of the housing was used obviously used first with the Spirit of '76, please read the serial number of this LADY 1200 carefully.
