It's not often that a YouTube video on a technical topic gives one goosebumps. And it's not often that someone unpacking a computer makes history.
Francois Rautenbach a computer hardware and software engineer from South Africa achieves both with a series of videos he has quietly posted on YouTube.
It shows the "unboxing" of a batch of computer modules that had been found in a pile of scrap metal 40 years ago and kept in storage ever since. Painstaking gathering of a wide range of evidence from documents to archived films had convinced Rautenbach he had tracked down the very first Guidance and Navigation Control computer used on a test flight of the Saturn 1B rocket and the Apollo Command and Service Modules.
Apollo-Saturn 202 or Flight AS-202 as it was officially called was the first to use an onboard computer – the same model that would eventually take Apollo 11 to the moon. Rautenbach argues that the computer on AS-202 was also the world's first microcomputer. That title has been claimed for several computers made in later years from the Datapoint 2200 built by CTC in 1970 to the Altair 8800 designed in 1974.
The AS-202 flight computer goes back to the middle of the previous decade.

The first 60 percent of the page's HTML is unrelated crap.
...and, since I don't bother downloading CSS (or fonts or anything else that isn't readable text), that page looks to me like it was produced by an 8 year old.
The link really deserved a fragment identifier [timeslive.co.za] from the submitter.
...and, wow, what a ridiculous number of (completely unnecessary) scripts.
.
Interestingly, AS-202 and AS-203 didn't fly in numerical order, as shown by another page with an Apollo/Saturn V timeline. [wikipedia.org]
Additionally, Apollo 2 was scrubbed and "Apollo 3" was apparently never assigned to any mission.
Apollo 1 was destroyed on the pad during testing.
A fire in a 100 percent oxygen environment at 1 atmosphere pressure with nylon stuff everywhere and a hatch that opened inward killed Grissom, Chaffee, and White.
N.B. The internal pressure became so great that it ruptured the capsule.
NASA and its contractors rethought a huge amount of stuff after that.
The Apollo capsule got a thorough design review|redesign.
It appears that even-more-integrated electronics were a part of that.
