Re: Beyond the nits about the bits
Indeed. I have just finished reading the original programming guides and internal documentation on the Apollo Guidance Computer. The low level hardware instruction set was what we would today call a RISC machine, with highler level operations handled by functions. It had a multi threaded operating system. To make life easier for the application programmers (ie, the ones who designed the guidance and navigation, and how to land on the Moon) they had a virtual machine.
We still have a hell of a lot to learn from these Luminary's (and lets see who gets THAT reference!)
