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.
