Programmable calculators collection

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.
