Vintage Calculators

[hamid_1]

I've accumulated various old calculators over the years. Nothing as elaborate as the HP though. Here's a partial listing by display type.

Red LED:

Commodore 776M https://www.calculator.org/calculators/C..._776M.html

Commodore scientific with internal rechargeable battery

Sinclair Executive https://en.wikipedia.org/wiki/Sinclair_Executive

Calcu-Pen http://www.vintagecalculators.com/html/calcu-pen.html

Green Fluorescent Display:

Casio J-2  http://www.casio-calculator.com/Museum/P...20J-2.html

Prinztronic c-mos 1 (made by Toshiba, I think) http://www.vintagecalculators.com/html/c-mos_1.html

LCD:

Texas Instruments TI-36X Solar Scientific (this is the one I mostly use)

Casio MS-300M (can multiply, divide, add or subtract hours, minutes and seconds as well as decimal numbers)

Canon Snoopy and Woodstock calculator https://www.worthpoint.com/worthopedia/v...-440499308
Much like any other basic calculator, except when you store something in memory, a graphic of Woodstock appears. Snoopy appears lying down exhausted when there's an error, such as divide by zero.

A couple of calculator watches, Zeon Databank and Casio CMD-40 which also works as an infra-red remote control. https://www.worthpoint.com/worthopedia/c...-518647348

There's a few others, mostly no-name very cheap or free ones. I once had a free Sony 3.5" diskette shaped calculator that came with a pack of blank disks. When the shutter was slid open, it exposed the solar cell, switching on the calculator. It looked like this IBM one: https://www.itmanagement101.co.uk/ibm-3-...alculator/
