I expect many of you already knew that an HP-65 programmable calculator was used on the Apollo-Soyuz Test Project (ASTP) flight. It's been a long-time aspiration of mine to find the programs that were used. I recently put together a web page that summarizes what I've been able to find out so far. I hope it's of some interest.

Here's a tidbit for collectors: two HP-65s were flown — it appears that only one made it into the Smithsonian. So where's the other?

I'm well aware of the HP-65 that someone in Germany has been trying to sell for almost 10 years — despite the absurd asking price (€5000), the seller himself has admitted the calculator itself is not flown — he claims the price is so high because of the card included in the auction that has all 5 crew signatures.

I checked my photos from touring the Stafford Air & Space Museum and do not see a calculator on display, but it might be worth inquiring to see if the second HP-65 is in their collection (if you haven't already).

And great web presentation about a specific artifact!
