Texas Instruments Studio 29? We were really surprised to locate in October 2016 this unusual looking calculator on the Italian eBay site. We knew already the original version of the Studio 29 with its strange looking yellow-brown keyboard plate but we didn't expect even a second version of it. At first glance this Studio 29 - manufactured in 1978 for Koh-i-Noor Hardtmuth - looks like a hybrid of two different products:
|• The basic functionality
is borrowed from the TI-15 introduced in 1976
• The silver keyboard plate is... unique - and not from the TI-30
Looking closer at the Studio 29 reveals a strange difference to the TI-15 sold in Europe - the [K]-key is missing!
Don't miss the model 40 and it's
