Now they seem to have have found a SCRAPPED Apollo
guidance
computer and am rebuilding the missing pieces.
Wow. What a great site (and that guy has mad skills, everything from
repairing old Teletypes, through designing boards, to repairing analog
stuff). Just 'wasted' a good chunk of the morning reading back through
it; tons of really neat things (including recovery of the very first
FORTH, along with a lot of Diablo drive - from the Alto - repairs).
As a shortcut, here:

is the backstory on the AGC; about 1/3 of the way down, in "Restoring an
Apollo Guidance Computer, part V".

The project and videos were mentioned on the list back in December.
There's an interview with Jimmie there (4:13) with more details about the backstory.

Yes, that would be Carl?s ?day to day? blog (http://rescue1130.blogspot.com/). He is also
on the list, lurking in the background. Carl, are you there?
Ken Shirriff has also several deeply researched blog articles on specific AGC topics
(righto.com).
Mike has some very interesting posts on his AGC FPGA emulation work here:
