Texas Instruments - TI-35 PLUS

Description

Brand: Texas Instruments
Model: TI-35 PLUS (Second revision)
Type: Scientific calculator
Picture: TI-35 PLUS
Batteries: LR 44 x 2
Lifetime: Introduced: 1989
Terminated: unknown
Notes: This calculator seems to be the successor to the TI-35 II, it is however a completely different calculator.

Some of the differences. This one has a 10 digit accuracy and uses two separate digits for the exponent. It also includes hexadecimal, binary and octal operating modes. Complex functions are also included. At least I suspect they are, there is a "CPLX"-mode but I havenŐt been able to figure out how that works. I still got an error on √-9.

Changing batteries is a little bit tricky. The batteries should be placed under the foil instead of the other way around.
