Texas Instruments 30/super? This was our first reaction when fellow collector Michel Pfister from France shared already some years ago a picture of this rare calculator with the Datamath Calculator Museum. It is obvious that the model 30/super - manufactured for Koh-i-Noor Hardtmuth - is a hybrid of three different products:
|• The basic functionality
is borrowed without any doubts from the
TI-30 introduced in 1976
• The double-shot injection molded keys are known from the Business Analyst-I
• The printed Texas Instruments logo between the display and keyboard are carried over from the European TI-45
In March 2011 our friend Michel surprised us with another calculator manufactured for Koh-I-Noor Hardtmuth, the odd Texas Instruments 1265 based on the TI-1265. And instead of pictures we even received a box from France with the real hardware as a loan for some deeper investigations and photo sessions. Thanks!
In the meantime Marie Lisa Collas, a fellow calculator collector
living in Luxembourg, located the predecessor of the model 30/super
known as model professional. Don't miss the
colorful SILCA 48.
