In preparing for this bit of Foolishness, I found these 4 paragraphs...
On September 12, 1962, in front of a packed crowd in Rice University’s football stadium, President Kennedy was willing to propose the building of a giant rocket more than 300 feet tall, the length of a football field, made of new metal alloys, some of which have not yet been invented, capable of standing heat and stresses several times more than have ever been experienced, fitted together with a precision better than the finest watch.
In 1969 at the top of the Saturn Rocket was the Apollo spacecraft. One of the most important components inside of the Saturn was its guidance computer. The computer capacity of the mainframes in the Control Center [of NASA’s Manned Spacecraft Center in Houston] was smaller than that of the desktop systems of the 1980s, and the onboard computers in the command and lunar modules had less capacity than some pocket calculators.
The Apollo Guidance Computer, which weighed 70 pounds, had only 36K of RAM and 2K of ROM. But it was able to guide 27 men to the moon’s orbit and bring them back safely.
These billion-dollar satellites and spacecraft went into space with computational power that’s the equivalent of a Commodore 64 Home Computer (introduced in January 1982).
A Million is big (a thousand thousand). Congress loves to spend Billions of Dollars (a thousand million). They are getting all too familiar with how easy it is to throw around Trillions of Dollars (a thousand billion). Once they find out that there is such a thing as a Quadrillion (a thousand trillion) all is lost.
In the world of computing there a measure of computing speed called a Petaflop or the equivalent to One Thousand Trillion Calculations Each Second.
The Italian Oil Company ENI has a Supercomputer (the HPC4) that has capacity to do 18.6 Petaflops, and when combined with the existing HPC3, the system reaches a computational peak capacity of 22.4 Petaflops.
I may have lost you. Allow me to bring you back…
That’s 22.4 Thousand Trillion Calculations Each Second
If Apollo 11 had this kind of computing capacity it could have gone to the moon and back without leaving the launch pad.
Would I kid u?

Lagniappe: This Blog Posting was first published in July, 2018. If we would say to a 2023 Computer Smart Guy, "Man O Man, 22.4 Thousand Trillion Calculations Each Second! That's really fast!", he would probably come back at you and say to you, "That's nothing. Let me tell you about today's computers..."

Very Interesting..... I have read that the average new car has much more computing power than the Apollo spacecraft.
New car?
Commador 64 is way older than a new car. 😀
I did not see that last line coming, which is what makes your Foolishness so refreshing.
The computer became overloaded and the crew saw a 1202 warning. Don't you just wish we could somehow get where we are going today without the GPS gal's advice.

“Petaflop”??? that sounds nasty!!
That was two years before Elon Musk was born and long before anyone thought about a self driving car. The Gemini computer overloaded and flashed an error code 1202 which indicated the computer was overloaded.
Then came Armstrong’s voice over the radio again, this time marked a slight note of urgency. “It’s a 1202… What is that? Give us a reading on the 1202 Program Alarm…”
He calmly took over manually and set the Eagle on the surface of the moon. If Neil was alive today, I doubt he would trust the Telsa with all it's computing power to be his driver.
