A group of fans of vintage computer technology has restored the 50-year-old on-Board control computer of the spacecraft "Apollo". Enthusiasts set an unusual goal - to use the device, which participated in the flight to the moon, for the extraction of cryptocurrency.
The Apollo spacecraft control computer was one of the first to be equipped with integrated circuits, which made it compact and not the size of a room. There is no traditional processor in the device - 5,600 electronic gateways were used instead, which made it possible to perform about 40,000 simple mathematical operations per second. By today's standards, this is extremely small, but this speed was enough to control the spacecraft in real time.
After the computer was restored, the developers reprogrammed it to extract bitcoins, which is completely different from its original tasks. Enthusiasts have achieved their goal, but the experiment can hardly be called successful. The technique that once controlled the flight does not have enough power for mining. It takes about 10 seconds to calculate one bitcoin hash. For comparison, specialized equipment is capable of processing trillions of hashes per second, and a small USB miner for $ 70 produces 130 billion hashes per second.
“The computer is so slow that it will take him about 4 × 10 23 seconds to successfully mine one bitcoin, which is a billion times the age of our universe,” said Ken Shiriff, one of the enthusiast group members.
