Programmable calculators collection

Welcome to my collection of vintage calculators, organisers and pocket computers. This site aims to describe and provide specifications for many calculators and pocket computing devices.

The collection on this site is focused around vintage hand-held, programmable, electronic calculators. Desktop and mechanical calculators are not covered. The oldest calculator in the collection dates from 1972 , about the time of the invention of the integrated circuit (IC or chip). The latest calculators include models like the HP-50G and TI-NSpire

A special section is reserved for aviation calculators . I'm not a pilot, so I don't have an immediate use for these devices. But the purpose build devices do appeal to me.

Initially this site started with just the devices in my collection, but it has grown beyond that to include items that just interest me but don't neccasarily own. In that sense it is more a collection of calculator specifications, than of actual calculators. I have gathered specifications from manuals, personal experience and from the internet.

Please note
This site is in a constant state of construction. Even though I do my best to be as accurate as possible, no part of this site is garanteed to be complete or correct. If you find anything to be incomplete or inaccurate, please use the feedback option on that calculator's page.
