Besides, people have made working replicas of the AGC.
I guess they are part of the conspiracy too. 
That's been pointed out. His argument is that unless they use completely authentic hardware, i.e., iron core rope memory and vintage ICs, it's not a valid comparison. Which, actually, might be a valid point.
What he carefully ignores is that the programs that he says are "jibberish" and can't possibly run,
DO run on these replicas. The hardware is irrelevant - his claim was that the software itself couldn't function. Which pretty well establishes his level of
expertise when it comes to computers.
What I find interesting is that he always ignores questions that he doesn't have a ready answer for. While he has
very occasionally accepted correction on one point or another, he usually retreats to:
(a) he's an
Engineer Aerospatiale and you don't know what you're talking about;
(b) the Apollo engineers deliberately put errors in the plans as a "joke" because they wanted to plant clues that it was a hoax; or
(c) all the project personnel were sworn to secrecy, enforced by death threats from the
Evile CIA.
