Computer from the Saturn V Rocket

Amazing how much has changed, and what they were able to do with that primitive technology...

Pretty cool. I was at that museum in the '80s, I was 16 or so and really taken with the place. You can really appreciate the size of those rockets standing underneath one.

Haven't watched the video yet, but wondering if they programmed it in machine language, which was simple then, and compact, and lightning-bug fast. some coders think in it, code like musicians. blows my mind...

I was standing on the beach across the lagoon from the cape and got to watch one of those Saturn Vs take off one time. I remember when the shock waves started to hit us you could feel your chest start to vibrate. As the shock waves hit I felt tears start to run down my cheeks and don't know why. I don't know if there was something emotional that I was feeling or if it was a result of the shock waves hitting me. It was a strange feeling. I remember it made me feel rather insignificant.

Thirty years ago I managed to learn machine or 'assembler' language for the 8088 processor [IBM] family, and man you are right....for things like sorting algorithms it sure beat anything you could compile in BASIC or Turbo Pascal, but for stuff where speed wasn't vital it was not worth the effort. That was when a 1 MHz processor was 'fast' though....now anything no matter how sloppy seems fast at a million times that.... :D A program I wrote back then had a section where parsing through a large database might take 2 or 3 minutes even with the assembler subroutines, so I put in an elaborate tallying and graphic display to make sure the user didn't think the program has crashed and to keep the user from being bored.....I ran it on a 4 GHz machine for kicks a couple years back, and you couldn't even SEE the fancy display because it came and went so fast. :lol:

Core memory. That's the stuff that was in use in the computers I learned on in school. That was back in the days of punched tape, and we had to punch our own tapes to bootstrap. Anybody who had to program in Machine Language remember repertoire cards? The first "hard drive" I ever worked on was 4ft tall and 2ft in diameter. A drum, actually. No Integrated circuits. "Dense-packs" were the cutting edge. No plug-n-play.

It was interesting from a technical standpoint, but life is so much easier these days.

It amuses me that some chuckle-head who slaps together desktop PCs from off-the-shelf parts thinks he's a computer expert.

NYC 1960-something. Night class in programming IBM computers. Reel to reel tape drives and punch cards. The program was fed to the computer on punch cards and the reels started reeling. Very impressive to a simple guy...

Interesting fact. In 1965 100% of the integrated circuits produced in the world went to project Apollo. Before that they were mostly used in the Polaris missile project and in various research computers.

Wow, punch tape. When first in journalism school in the early '70s we "saved keystrokes" in early computers and printed the stories on punch tape to feed into the typesetter. That awkward technology was very short-lived in the newspaper business.

I learned Land Surveying Cad on an old 256 that only used a DOS Tree and it was fast and reliable. When the office added the first Windows to it, it couldn't go two minutes with out freezing up.

In the early days of integrated circuits, it was found that they could fail in spacecraft orbiting the earth in the 300-400 mile region due to an area in the South Atlantic aptly named "The South Atlantic Anomaly". The higher radiation would fry the 1 and 2 layer boards that were state of the art back then and so many 'spy satellites' used hard wired logic boards. You wouldn't believe how large and heavy a wired 12K memory / logic board was.
