TI-35

The TI-35 series of scientific calculators was a line of calculators manufactured by Texas Instruments from 1979 to 1996. The original TI-35 was notable for being one of Texas Instruments' first use of CMOS controller chips in their designs, and was at the time distinguished from the lower-end TI-30 line by the addition of some statistics functions.

The TI-35 Plus, introduced in 1986, added hexadecimal and octal calculations and a 10+2 display (i.e. 10 digit mantissa with a 2-digit exponent), a feature carried onto the TI-36 and TI-30 lines.

The line was dropped in 1996, after ten years of coexisting with the TI-36 line, which had a very similar feature set. The number was also used on some models from TI's mid-80s portrait-aspect Galaxy line, but the functionality was closer to the contemporary TI-30 models.
