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.”
Meet the ambassador to the future
Tilly Lockey, 14, lost her hands as a toddler, but sees it as a massive opportunity to embrace technology. She chatted with ARTHUR GOLDSTUCK about the human of tomorrow.
It is a description that defines 14-year-old Tilly Lockey: She lost her hands at the age of 15 months, and now uses bionic hands to show the world how to overcome disability.
That could easily read as an advertisement for a prosthetics company, but Tilly refuses to be defined by marketing messages. She has not only embraced what is supposed to be a disability, but wants to become nothing less than an ambassador to the future.
That is in effect what she is achieving by pushing the boundaries of what is possible with artificial hands. It means that, eventually, she will have more capabilities built into her body than most able-bodied humans can imagine. She collaborates closely with Open Bionics, a start-up that is using 3D printing to create low-cost prosthetics with high-tech capabilities.
“I have very high hopes for the future,” she said during a chat on the sidelines of the SingularityU Summit at Kyalami north of Johannesburg. From Newcastle-on-Tyne in the United Kingdom, she was at the Summit as a guest speaker, chaperoned by her father Adam and sister Tia.
“When I started working with Open Bionics, I wanted it to include lighting, music, Bluetooth, a projector in my palm, all over-optimistic things. But then I feel that is not too far away, and then a disability would turn into and enhancement of normal human hands. I’m really excited about it.
“I know there’s a couple of things they are working on right now, like trying to get the built-in battery thinner, because it’s hard to get overcoats and jackets over it, so they are trying to get the hands slimmer. They’re working on haptic feedback, to give a sense of touch of vibration, which tells me of I have a good grip on something. It could be coming soon. These hands I’m using now were made in the past five years. In another five years, I think we’ll have all of it.”
The hands in question are called Hero Arms, which its creators, Open Bionics, say is “the world’s first clinically approved 3D-printed bionic arm, with multi-grip functionality and empowering aesthetics”.

How Tilly Lockey became a Hero
Part 2 of ARTHUR GOLDSTUCK’s interview with Tilly Lockey explores her amazing career.
This is the second part of this series of articles. To start from the beginning, click here.
Tilly Lockey was diagnosed with Meningococcal Septicaemia Strain B when she was 15 months old.
Her mother spotted the tell-tale signs one day in 2007: a fast-spreading skin rash that looks like pinpricks, along with symptoms like lethargy and bruising. She was rushed to hospital, but the bacterial poisoning spread so aggressively, doctors gave Tilley no chance of survival. They had to make a quick decision to amputate her hands to save her life.
Twelve years later, her future truly came into focus: “I was surprised with really cool Alita: Battle Angel bionic Hero Arms and went on the blue carpet at the world premiere of the movie with Rosa Salazar and director James Cameron.”
That pivotal moment in her life would not have been possible without the intensive efforts of her mother, Sara, to raise funds to buy something better than the metal prosthetics issued by the National Health Service in the UK. She increased Tilley’s profile with a campaign to “Give Tilley a Hand”, and today works as a fundraiser and events organiser for the Meningitis Now support group. Her involvement in an event meant she was unable to join Tilley on her trip to South Africa last week, when she spoke at the SingularityU Summit. After coming off stage, Tilley told us that Sara was her biggest inspiration in her life, and the closest to a role model.
“I’m usually a speaker at her events. I tell everyone my story and what I’m doing now and give these kids inspiration, because they often feel they can’t do anything because of what Meningitis did to them.
“I am home schooled now, which is pretty cool, because I’m able to have a career and get educated at the same time. I feel I can do a lot of things that friends can’t do. I can take a whole class on an aeroplane. I have a great time traveling and meeting so many inspiring people who are making a difference in the world.”
The form of Mengingitis that attacked her leaves hidden scars and issues that only become apparent years later. She is almost absurdly cheerful about the challenges that have faced her.
“I personally figured out that my left leg had stopped growing. I’m still finding out things it has caused, but you survive. At least I’m here and I’m alive.”
It does help that she’s comfortable in the spotlight, happy to give interviews, and eager to show what she can do with her bionic hands.
“I want to go into public speaking a lot more, and it could be an option as career. I want it to continue because it’s a lot of fun, and I feel I’ve got a story to share. If I can inspire people to change the world, I will. “
Her travels this year will still take her to Barcelona, Jakarta and New York. In the Big Apple, she will accept a humanitarian award, and intends “to give a funky speech”.
In Jakarta, Indonesia, she will take part in a fashion catwalk and do a makeup tutorial live. She learned to do makeup with one of her bionic hands when she fractured her right elbow in a fall at school
“I got makeup for Christmas and wanted to play with it, and got the idea of doing it with an open hand. It took a lot of perseverance and patience, but after studying how to do it, I was able to recreate a full makeup routine using one hand. It wasn’t a great situation at the time, but now I’m happy it happened because it got me into doing what I do now.”
What she is doing with makeup is remarkable in its own right. She gives tutorials on YouTube, where she says she is “kinda new”, as she has “only around 16,000 followers”. That may well soon expand into cooking videos.
In other words, everything is an opportunity: “I could be sad, just sit on my bed and cry, or I can live my life and realise what I’ve got: these amazing bionic Hero Arms.
“All I want to do is help give people confidence in themselves, accept who they are, accept their scars and everything about them. That they don’t have to impress everybody and just be themselves.”
