INDEX:  — navigate the whole project from here. The project examines two 1969 computers – the Apollo Guidance Computer (AGC) and the HP2116  – plus our own P82 development, aided by the HP9825. In post 12 we add 2001 space odyssey to show the imaginary alongside the reality. The ISS – International Space Station – adds a reality check to the 2001 odyssey.

extra text ???

That note in the top corner along with the media cuttings was written as the first moon step was taken: Monday morning, July 21st 1969 at 3:56:20 seconds (!) a.m. BST (British Summer Time). Transmission was being audio recorded via a microphone in front of the TV !!

[Media side note: the 80 page special issue publication contained 11 full page colour adverts for alcohol and seven for cigarettes.]

The most amazing series is from “CuriousMarc” with a very talented team re-building a complete operating AGC complete with DSKY ready for the 50th year moon landing anniversary of June 2019. There are about 26 episodes, the first three are listed below [I leave full web addresses visible] selected parts of their process are embedded in our project posts.

Images of the P82 project are of course all from our own stock !  Also taken specially as the machine remains here and in good shape.

Information on the 9825 computer.
Photos are ours because we have the 9825 with plug-in 16-bit interface and full documentation – right here!
