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 . Not because I am a pilot, just because the special build devices appeal to me.

Initially this site started with just the devices in my collection, but has grown beyond that to include items that just interest me but that I 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.
