In 1969 computer chips had not been invented. The maximum computer memory was 256k, and this was housed in a large air conditioned building. In 2002 a top of the range computer requires at least 64 Mb of memory to run a simulated Moon landing, and that does not include the memory required to take off again once landed. The alleged computer on board Apollo 11 had 32k of memory. That's the equivalent of a simple calculator.
What a gullible rube. 99.99% of the memory of any computer game is for the graphics. You don't need graphics if you have a window. Calculating the physics is a lot simpler than calculating the graphics. A long time ago I wrote a computer game in GW-basic on an old Zenith computer to land a lunar module on the Moon. Its only graphics was a print out of the altitude, down-range distance, vertical velocity, horizontal velocity, thrust, and fuel remaining. It took less than 2 kb. A "simple calculator" is all you need to land on the Moon. The hard part of the mission, the orbital mechanics, was solved back on Earth using the supercomputers of the day and the results radioed up to the spacecraft.
Plus, it had pilots. People on board to to judge the situation and make changes when needed. For example, if Apollo 11 had been a probe, its autopilot would have taken it into a boulder field, and it likely would have crashed. But Neil went manual and guided the thing down, using his skill, experience and his eyeballs and brain to make corrections the computer could not.
Tindarormkimcha, before Apollo 11 landed, there was unmanned probes sent by both the former Soviet Union and NASA that landed on the moon. If landing on the moon is impossible with two trained pilots on board the lander, should it not be also impossible to unmanned landers? Yet other conspiracy theorists try to explain away the presence of reflectors, something verifiable by any with the right equipment, by saying NASA sent them unmanned.
The presence of reflectors is undeniable, yet if they could be sent unmanned, which the Russians did do by the way, then the computers of the time could also be enough to send trained pilots to do the same.
You can't have it both ways.
