The hacker, the scrapheap, and the first Apollo computer
August 31st, 2016
A Tshwane (Pretoria) computer engineer has tracked down one of the great treasures of the computer age – the first space flight guidance computer.
ARTHUR GOLDSTUCK tells the story.
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 Tshwane, 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.
The Rope Memory Modules from Flight AS-202’s Guidance Computer.
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.

In a series of three videos, he extracts the software, shows how the computer was constructed, and uses a hospital X-Ray machine to inspect its insides. The third video starts with the kind of phrase that often sets off the hoax-detectors in social media: “Okay, so you guys won’t believe what I’ve been doing today.” But, in this case, it is almost unbelievable as Rautenbach takes the viewer through a physical inspection of the first Apollo guidance computer.
