Within the TI-1000 family we discovered in the past ten years some very interesting design variations sold either as a Texas Instruments product, as a Texas Instruments product through different sales channels, or even without the TI logo. Just recall some TI-1000's, TI-1025's and TI-1050's:
• Texas Instruments
TI-1000 with a silver
design instead the original gold design • The TI-1025 sold by by the Dutch department store HEMA • The "silver" calculators sold by Western Auto as Citation • The "brown" calculators sold by Western Auto as Citation • The "woody" calculators sold by Western Auto as Citation |
And how does this Texas Instruments 1050 fit into the line? Thanks to our fellow calculator collector friend Michel Zwawiak in France, we know the roots of this strange product: It was sold in 1977 by Koh-I-Noor Hardtmuth, a manufacturer of pencils, pens and art supplies based in the Czech Republic and already known for the incredible Texas Instruments 30/super.
