HP65 Vintage Calculator - First programmable in space

Recently I found this gem on local classifieds, it was advertised as dead, but in excellent condition :)
After I got it i recharged the batteries and she still worked!

Next I need to make a power supply for it and some PAC programmable magnetic cards.

Great site with emulator and some technical details. http://www.teenix.org/
