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.”
Netflix lifts lid on first Nigerian Original
The streaming giant is set to increase its investment in Nigerian and African entertainment
The working title is the “Akin Omotoso Project”, but the world will soon get to know it by a snappier title. It is the first African original scripted series from Nigeria commissioned by Netflix. To be directed by Akin Omotoso, with Daniel Oriahi and CJ Obasi, it is planned to be a six-part series.
Netflix this week announced that it will increase its investment in Nigeria’s creative community, starting with the Akin Omotoso Project,
The series will star Kate Henshaw and Ade Laoye in leading roles, alongside other Nollywood greats and fresh faces, such as Richard Mofe Damijo, Joke Silva, Fabian Adeoye Lojede, Kehinde Bankole, Ayoola Ayolola, Toyin Oshinaike, Goodness Emmanuel, Ireti Doyle, Fabian Adeoye Lojede, Bimbo Akintola, Tope Tedela and Ijeoma Grace Agu.
Set in modern-day Nigeria and shot in Lagos, this drama tells the story of Kemi, a goddess reincarnated as a human to avenge her sister’s death. But first, she must learn how to use and harness her superpowers to defeat her enemies and save her family from destruction. The series will be produced by Rififi Pictures.
Over the last year, Netflix has started to invest in the creative community – bringing Nigerian stories to audiences all around the world. These include: popular movies such as Merry Men, The Real Yoruba Demons, The Wedding Party 2, King of Boys; Nollywood classics like The CEO, October 1 and The Figurine; and films by renowned Nigerian director, Kunle Afolayan, such as Mokalik. These much loved Nigerian movies will join Nollywood favorites such as Chief Daddy, Lion Heart and box office hit, The Bling Lagosians.
Ted Sarandos, Netflix’s Chief Content Officer said: “Movies like King of Boys, Merry Men and The Bling Lagosian have shown how much our members love Nigerian movies. So we’re incredibly excited to be investing in Made in Nigeria stories – bringing them to audiences all around the world”.
Dorothy Ghettuba, who leads African Originals at Netflix, said: “I’m excited that in the same week that we’re launching Queen Sono, we had the opportunity to be here in Lagos with Nigerian storytellers to share plans of our first Nigerian original production. Our continent has a wealth of diversity, multiplicity and beauty in stories that have yet to be told and we want to be top of mind for creators in Nigeria, especially when it comes to stories they haven’t had a chance to tell yet.”
Last month, Netflix enabled Nigerian members to pay for its service in Naira – making it easier for subscribers to use Netflix. Members can enjoy a wide range of diverse, quality entertainment, including African Originals like Queen Sono, which launches this Friday, 28 February. Other African Originals launching this year include Blood & Water and Mama K’s Team 4.
Load-shedding generator could blow your insurance
Load shedding is going to remain a reality in South Africa for at least the next 18 months as Eskom conducts maintenance on its ageing power plants – but don’t go rushing off to buy your own alternative power supply without first checking how it’ll affect your home insurance.
That’s the warning from King Price’s partner of client experience, Wynand van Vuuren, who says it’s vital that alternative power supplies like generators are installed and certified by accredited electricians. If these devices are installed or used incorrectly, you might not be covered for any damages that may result.
“There’s been a huge upsurge in the number of people using portable generators to keep a few basic essentials going when the power goes off,” says Van Vuuren. “But what most people don’t know is that you’ve got to have them installed professionally by an electrician. You can’t just stick your generator in the garage with an extension cord running through the window.”
Here are Van Vuuren’s top tips for staying covered and charged safely during load shedding.
Do your homework
Know what your alternative power options are, and the pros and cons of each.
An inverter changes DC power from a battery into AC power that you can use to operate all kinds of devices. Obviously, it needs a battery pack to be useful. These batteries are either charged by solar or from the grid while the power is on.
A portable generator is a little generator on wheels that you see people buying in their dozens at Makro and Builders Warehouse over the weekend. They’re relatively cheap and easy to operate, but can’t keep big appliances running.
Stationary generators are usually slightly bigger units that are installed permanently, and switch on automatically when the power goes off. They’re more expensive, but have greater capacity.
Stay safe – and covered
Apart from keeping your lights on, the different power options all have one thing in common: they must comply with safety guidelines, and be installed by a professional.
“I know of guys who take their portable generators to a different mate’s house every weekend so they can watch the rugby during load shedding,” says Van Vuuren. “It’s not as smart an idea as you think: not only is the generator not covered, but any possible damage caused by the generator won’t be covered either, because it’s not properly installed.”
It’s also essential that portable generators are operated in open areas with good air flow, to prevent carbon monoxide build-up, and that fuel is stored safely in an area with adequate ventilation.
Keep your bases covered
If you’re using a generator or an inverter, make sure they power your electric fence, gate and alarm as well, as burglars are all too quick to exploit opportunities caused by power outages. If you don’t have an alternative power supply, make sure your fence, gate and alarm have a battery back-up that’s sufficient to see you through your darkest moments.
Oh, and make sure your generator’s insured as well, in case it’s stolen or struck by lightning. You would typically insure a portable generator under your home. A stationary (standby) generator becomes a fixed fitting once installed and must, therefore, be added to your buildings cover.
Beat the downs with UPS
Another major headache for South Africans is the power surge that can happen when the power is switched back on after load shedding, with big-ticket appliances like dishwashers, televisions, fridges, coffee machines and sound systems all at risk.
“We’ve seen claims for ‘fried’ computer equipment, appliances and even distribution boards caused by power surges,” says Van Vuuren. “This can be avoided by installing a UPS (uninterrupted power supply) – which doesn’t come cheap – but is advisable to at least protect costly items, like TVs and sound systems, and items with intrinsic value, like laptops.
“The other alternative is to manually disconnect your more sensitive appliances from the power supply and reconnect them after the electricity is switched back on.”
