A Tshwane 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.
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.
His video succinctly introduces the story: “On 25th August 1966, a very special computer was launched into space onboard Apollo flight AS-202. This was the first computer to use integrated circuits and the first release of the computer that took the astronauts to the moon. Until recently, the software for the Block 1 ACG (Apollo Guidance Computer) was thought to be lost…”
One can be forgiven for being sceptical, then, when he appears on screen for the first time to say, “I’ve got here with me the software for the first microcomputer.”
Then he unwraps the first package and says: “Guys, these modules contain the software for the first microcomputer that was ever built, that was ever used.”
The goosebumps moment comes when he reveals the NASA serial number on a device called a Rope Memory Module, and declares: “These modules are the authentic flight AS-202 software modules. These were found on a rubbish dump, on a scrap metal heap, about 40 years ago … and we are going to extract the software from this module.”
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.
How did an engineer from Tshwane stumble upon one of the great treasures of the computer age? He has tended to avoid the limelight, and describes himself as “a hardware/software engineer who loves working on high-velocity projects and leading small teams of motivated individuals”.
In an interview this week, he added: “I am the perpetual hacker always looking for a new challenge or problem to solve. I have experience in designing digital hardware and writing everything from embedded firmware to high level security systems. Much of the work I did over the last five years revolved around building new and creative payment solutions.”
The breadth of his work gave him the expertise to investigate, verify, and extract the magic contained in the AS-202 computer. A global network of contacts led him to the forgotten hardware, and that is when the quest began in earnest.
“I got interested in the Apollo Guidance Computer after reading a book by Frank O’Brien (The Apollo Guidance Computer: Architecture and Operation). Most of us grew up with the fallacy that the AGC was less powerful than a basic programmable calculator. I discovered that this was far from the truth and that the AGC was in fact a very powerful and capable computer.
“I started communicating with experts in the field and soon realised that there was a wealth of information available on the AGC and the Apollo space program in general.
“One day I received some photos of AGC Rope Memory modules from a friend in Houston marked ‘Flight 202’. After a little googling, I realised that these modules contained the software from Flight AS-202. As I learned more about AS-202, I discovered that this was the first time the AGC was used in an actual flight.”
Rautenbach eventually tracked down the source of the photos: a man who had picked up the entire computer, with memory modules, at an auction, as part of a three-ton lot of scrap metal.
“At one point he opened up to me and said he had other modules. He admitted he had a full Apollo guidance computer, and my theory was that it was used to develop the Apollo 11 guidance computer. He sent me more information, and I thought he had THE computer.
“He’s got all this junk in his backyard. He started selling stuff on eBay and one day got a visit from the FBI wanting to know where he got it. He was able to find the original invoice and showed it to them and they went away. But it scared him and he didn’t want to tell anyone else in the USA what he had. Not being from America was an advantage.”
Rautenbach flew to Houston last year, opened the sealed packages and filmed the process.
“This was the first microcomputer. I opened it and played with it. I realised this was the first computer that actually flew. I also found Rope Memory modules that said Flight 202, and he didn’t know what that was. I found it was from AS-202, and I said we can extract stuff from this.”
Rautenbach paid a deposit to borrow the units and have them sent to South Africa, so that he could extract and rebuild the software. He also made contact with Eldon Hall, leader of the team that developed the Apollo guidance computer and author of the 1966 book, Journey to the Moon: The History of the Apollo Guidance Computer.
The correspondence helped him verify the nature of the “scrap”. The Apollo command module from flight AS-202 was restored and is now on permanent display on the USS Hornet, the legendary aircraft carrier used to recover many Apollo command modules and now a museum. However, the computer parts were sold as scrap in 1976. And NASA never preserved a single copy of the software that had been used on its first guidance computer.
Fortunately, a sharp-eyed speculator realised the lot may contain something special. He sold off some of the scrap over the years, until that visit by the FBI. He still prefers to remain nameless.
Last week, on the 50th anniversary of the launch of AS-202, Rautenbach quietly began posting the evidence online. He also announced that the raw data he had extracted would shortly be made available to anyone who wished to analyse it.
His videos on the unboxing of the AS-202 computer and the extraction of the software can be viewed on YouTube at http://bit.ly/as202, where he also plans to post instructions for accessing the software.

Apollo comes back to Pretoria
Francois Rautenbach points out that South Africa played a prominent role during the 93 minutes of flight AS-202: “Pretoria is mentioned no less than three times in the post-flight report. The AS-202 flight actually reached it’s highest point above South Africa. The telemetry data from the flight were recorded on computer tape at Hartebeesthoek and later shipped back to NASA.”
Showmax launches half-price mobile streaming service
A new streaming product designed specifically for Africa, featuring TV series as well as African content and live sport, is aimed at filling the gap in subscription video on demand services
The subscription video on demand (SVoD) model, which originated in the USA, spread rapidly in countries where uncapped broadband is affordable and widely available. However, because the model also relies on consumers being comfortable with transacting online and having ready access to credit cards, it has barely scratched the surface across Africa.
On top of that, smartphones are often the only only form of Internet access across Africa, and none of the popular SVoD services have been designed for the format.
Showmax says it plans to change this with the launch of a new mobile plan that costs 50% of the standard Showmax package but still features 100% of the same video content. Showmax is set apart by a combination of four pillars: hit African content, exclusive international series, topkids’ shows, and live sport, including weekly matches from the English Premier League, Italy’s Serie A, and Spain’s La Liga.
Showmax says the new plan is aimed at consumers who only use smartphones and tablets to watch video content. Video resolution peaks at standard definition to help reduce data consumption. As it is a product aimed at individuals, only one concurrent stream is included in the plan. As with the regular service, it is also available for a 14-day free trial.
“This is all about an African service developing a solution that meets the needs of African consumers,” saus Niclas Ekdahl, CEO of the Connected Video division of MultiChoice. “Customer feedback consistently points to local content and sport as some of the things that people value most from Showmax. That’s of course on top of the international series, movies, and kids’ shows that are our bread and butter. With all of that content now available in a product designed specifically for mobile usage, we’re doing something no other service can offer.
“On top of that, with groundbreaking deals like our new offer with Vodacom in South Africa, we solve the credit card issue through add-to-bill payment and the data issue by including data directly in the package. We’re looking to launch similar offers in Kenya and Nigeria soon.”
Both the standard and mobile plans include live sport, sport magazine shows and sport documentaries. The 2019 Rugby World Cup Final was streamed live on Showmax earlier this month, and the following is a selection of some of the football due to be live-streamed in November:
22 November: Levante vs Mallorca (La Liga)
23 November: Arsenal vs Southampton (Premier League)
24 November: Bologna vs Parma (Serie A)
25 November: Aston Villa vs Newcastle United (Premier League)
29 November: Celta Vigo vs Valladolid (La Liga)
30 November: Fiorentina vs Lecce (Serie A)
30 November: Chelsea vs West Ham United (Premier League)
Showmax’s mobile plan is currently available in Nigeria, Kenya, and South Africa.
