Haven't watched this video yet but am keen to do so as "ultimate" is a bold claim to make.

For my birthday recently I received 'SUNBURST AND LUMINARY: an Apollo Memoir' by Don Eyles.

I've only read a few chapters so far but it is a fascinating new (2018) account of how the AGC
software came about, and his part in it such as writing the P63 and P64 programs for the powered
descent to the lunar surface.
I've not got the Digital Apollo nor any other books on the AGC but if I had my druthers I would
wish to get the one by Eldon Hall, however it is a rather unusually expensive paperback so that
will have to wait.
