Remington Nixie Tube Calculator
I love nixie tubes. This is a twelve digit desk calculator with a nixie tube display manufactured by Remington Rand. Model number EDC1201GT. Most likely made in the early 1960s.

Electronic Calculators
Texas Instruments (TI) developed the first hand held electronic calculator in 1967. A few short years later the slide rule was all but dead. The TI-1200 (far left) was one of TI's most common
calculators. It was released in 1975.
The TI-86 Graphing Calculator (right) is the current calculator on my workbench. A bit overkill for what I need now but it was a
nice find at a swap meet for $10. It's got more memory (96Kb) than my first home computer.
Then again so does my phone, my camera, my watch...

Credit Card Calculators
As calculators got smaller, flat, credit card sized calculators appeared. Thin enough to fit in a wallet,
they were solar powered and could operate even in dim light.

and the CASIO SL-760 "Film Card".

Hioki 3208 Calcu Hi Tester
This is a unique combination of a calculator and Digital Multi-Meter (DMM) in one hand held unit. Not just both in the same package, the reading from the DMM will transfer to the calculator by pressing
the shift key which allows formulas to be calculated using the readings directly from the DMM readings.
The DMM section has ranges for AC/DC Volts, Ohms, and two milli-amp ranges. The DMM can be set to auto range and also has a zero adjust.
It's been labeled by some as "The Best Multi-meter Ever!" (referring to the combination of a calculator and handheld DMM in one package).

Pocket Spell Checkers and Translators
Not limited to math calculations, pocket computers were designed for different functions such as spell checking and translation for hundreds of different languages.
Today any tablet or smart phone will perform these functions.
