To the uninitiated, that almost sounds plausible, except for that fact that the computer and software for controlling a flight simulator is far more sophisticated and complex than that of the aircraft it is simulating.
I've been searching through my old documents with no luck to see if I could find the original post about simulating a lunar landing, but from one later post I think it may have been on New Zealand's
Trade Me Message Board about 2004 to 2007.
A computer "expert" came into a thread about the moon-landings and said that the AGC couldn't have possibly landed the lunar module because it had only kilobytes of memory, whereas it took many megabytes of memory for a lunar-landing simulation program to work.
This blew me away and made me laugh out loud, so posted something like, "Jeez, mate, they were actually
at the moon, so all they needed to do was look out the window to see it, and the computer didn't have to simulate a bloody thing!
"All it had to do was take information from the landing radar and other instruments and display them in meaningful terms so the Lunar Module Pilot could read them out to the Commander, who had to keep his eyes on the lunar surface and not the computer. The information included things like altitude, rate of descent, horizontal velocity, a few other less important items, and now-and-then, how much fuel was left in the tanks."
Here are some other posts of mine around that time at
Trade Me, where I'm dbb:
33. Twincam1 -- No 25. What's your point? Do you think the Apollo computers were not capable of the tasks required of them? Do you know how much computing power was required? IIRC, the lunar module computer had about 75kb of memory. Here's some info about it:
The guidance computer is a general-purpose digital machine with a basic word length, in parallel operations, of 15 bits with an added bit for parity checks. The instruction code includes subroutines for double and triple operations. Memory cycle time is 11.7 microseconds with a single addition time of 23.4 microseconds. The 'core rope', used for the fixed memory, has a capacity of about 36,864 words with an erasable memory (of ferrite core planes) of 2,048 words. The processor is formed from integrated circuits (ICs). The total computer weight is 29.5 kg.

34. Continued... The fixed memory contains programmes, routines, constants, star and landmark co-ordinates and other pertinent data. The erasable memory acts as an intermediate store for results of computations, auxiliary programme information, and variable data supplied by the G&N and other systems of the spacecraft.

The poster I was answering, Twincam1, was one of the very intelligent, open-minded kind of hoax-believers:
35. If you wanna believe the yanks drivel, cool.

36. Your racial prejudice helps us debate rationally whether or not the lunar landings occurred?

33. The Apollo Onboard Computers -- Here's a very good article about them: http://history.nasa.gov/afj/compessay.htm
People who REALLY know computers and study the article don't doubt that the computers could have done the job we're told they could. On the other hand, dopes tell us how much RAM etc. it takes to operate a flight simulator, while forgetting that the real computer didn't simulate ANYTHING. It just measured the environment and controlled a few things. It wasn't even completely necessary -- the astronauts could have operated the spacecraft without it -- it just made life easier for them.
