Ulf's Space Age CalculatorsDo you remember the beginnings ? The TI-Datamath 2500 from the early 70th's: ...and, you can see the design has already changed to the classical TI-Design, the SR-10 from 1974: Of course what has to be there....the Classicals from Texas Instruments: The famous TI-59 attached to a PC100 Printer (unbelievable expensive in 1979: 950 $ !) Another member of that family: The TI-58C which keeps the program even if the battery is empty !! Great progress in 1978 ! Also from that family: The TI-57 programmable calculator: A little later the scientific TI-51-III was available (1980) And again a little later the often used in school TI-30 appeared on the market... This is a very special TI-calculator...designed for people who often have to convert and calculate between decimal, hexadecimal and octal number: The TI-Programmer ! The TI Little Professor is a training tool for elementary mathematics sold already 1976 ![]() |
