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.
Dismantling
this LADY 1200 manufactured in September 1976 reveals a printed circuit board (PCB) identical with the later
production runs of the TI-1200 and TI-1250 calculators sporting the TMS0972 single-chip calculator
circuit.
Don't miss the rare Texas Instruments 1265 manufactured for Koh-I-Noor Hardtmuth.
