#TheApolloGuidanceComputer was built to navigate and guide the #Apollo astronauts to the moon. The #AGC and the inertial measurement unit (IMU) told astronauts where they were. The IMU contained gyroscopes and accelerometers. The IMU was calibrated using an onboard telescope and sextant. The AGC also controlled the engines and reaction control thrusters. The astronauts talked to the computer using verb and noun commands on DSKY (display and keyboard). The computer itself was make of core memory. The fixed memory was woven core rope memory. This is where the programs, constants, star charts, and landmark charts were woven and saved for each flight. The logic unit was make of integrated circuits (dual NOR gates). The computer could only run one job at a time. The executive determined what jobs to prioritize and run. The computer could restart programs, put them to sleep, and had very basic error checking. It was designed by MIT's Instrumentation Lab and built by Raytheon. There was one for the command service module and one for the lunar excursion module. New versions were built for every flight.
Many of the images and video came from this site. It is a great site to explore. Thanks for releasing this for the Apollo 50th Anniversary .

Ben Eater over at kzbin.info has a great series on making a computer from scratch on a breadboard. Was watching that at the same time as watching the AGC restoration video over at Curious Marc's channel kzbin.info as well as this breakdown of how the AGC works kzbin.info/www/bejne/rqmafZmearh-i7Ml.

The restart is described as being done that way: There were regular points of the program, called "way points", in which all the current data was saved in memory; when a restart had to be done, the computer was going back to the closest waypoint, reloading the data which had been saved at this waypoint, and restarting from this waypoint. But, as the address of the next instruction to be executed was stored in the program counter, and the data was still present in memory, it would have been simpler and more efficient to restart from the current address with the current data. Moreover, proceeding this way was meaning that memory had to be reserved to save the data, which was making less usable memory, and also it was taking time to save data at the waypoint, much time, time that the AGC could not afford to lose.

The IMU was not directly giving angles and speeds to the AGC, but pulses that the AGC had to count to update them. If the AGC was stopping working, it was losing the pulses, which means that the variations of angles and speeds were lost meanwhile. The AGC had special instructions (they call them "unprogrammed instructions"), PINC and MINC, to count (and decount) hardware pulses.

Some of this seems quite dumbed down, at least from my current vantage point, but other parts have much deeper diving. BTW one thing about the LM I only recently realized: The descent and ascent stages have totally different engines, but both can be throttled, both use hypergolic propellants pushed by pressurized helium, and both are controlled from the same point, in the cabin where the astronauts ride.

I don't know why this always bugs me so much, but when people talk about going to the moon and saying that the craft needs to leave the Earth's orbit, they are mistaken. At no point on any lunar mission did any craft leave the orbit of Earth. Think about it. The MOON is in Earth orbit. You don't LEAVE Earth orbit to go to the moon; you're just put on a highly elliptical orbit until you make another burn to orbit the moon. You're still orbiting the Earth though. You and your orbit around the moon are collectively in orbit around the Earth. You never leave Earth's orbit.

@@colinsouthern This is incorrect. The TLI burn from Earth that sent them to the moon put them on a trajectory known as "free return" - - meaning if they did nothing else, they would circle around the backside of the moon and be slung around and return to Earth. At some point on the way to the moon, once various systems checks were performed, they altered this trajectory that would allow them to be captured by the moon. At no point in time where they ANYWHERE NEAR a trajectory that would escape the Earth's gravitational influence. As for the ISS, the whole "centripetal force" explanation is a gross overcomplication. It doesn't matter how strong the gravitational field you are in is. If you are in free fall, you will be/feel weightless. Many people conflate this with the absence of gravity - which it most definitely is not. The notion that you leave Earth's orbit simply because you are experiencing weightlessness is erroneous logic. You can ride a free-fall type roller coaster right here on the surface of the Earth and experience literally the same state as a spacecraft in space. It's the same weightlessness, and it is not caused by any alterations in the gravitational field, but rather the result of being in free fall WITHIN that gravitational field - - which was the case for the vast majority of the trip to and from the moon. They are simply coasting. A free fall ride here on Earth just lasts a fraction of a second as opposed to the days Apollo astronauts experience en route to and from the moon / and in orbit.

@@colinsouthern No. STEP ONE : Launch STEP TWO : Get into Earth orbit STEP THREE : Translunar Injection - - AKA, send them to the moon. THIS trajectory was a free return. STEP FOUR : Midcourse (between Earth and moon - AFTER systems checks, etc.) taken off of a free return to a trajectory that would allow them to get into lunar orbit STEP FIVE : Get into lunar orbit. For example - the Apollo 13 explosion occurred during a point in the mission that they had already performed the maneuver that would take them OFF the free-return trajectory and on one that would allow them to perform a lunar insertion burn once arriving. They actually had to perform another burn to put the BACK onto a free-return trajectory and return. I feel like none of this is going to make sense to you.

Concerning the famous alarm 1202 (which caused much trouble in the control room, and which happened after Buzz Aldrin changed the radar switch from LGC to SLEW, because of an "erroneous" indication of the checklist), in a comment of the anomalies section of the mission report of Apollo 11, entitled "Computer Alarms During Descent, at page 16-13 you find this:(excerpt of the comment): "Any difference in phase or amplitude between the two 800-hertz voltages will cause the coupling data unit to recognize a change in shaft or trunnion position, and the coupling data unit will slew (digitally). The "slewing" of the data unit results in the undesirable and continuous transmission of pulses representing incremental angular changes to the computer. The maximum rate for the pulses is 6.4 kpps, and they are processed as counter interrupts. Each pulse received by the computer requires one memory cycle time (11.7 microsecond) to process. If a maximum of 12.8 kpps are received (two radar coupling data units), 15 percent of the computer time will be spent in processing the radar interrupts. The computer normally operates at approximately 90 percent of capacity during peak activity of powered descent.) When the capacity of the computer is exceeded, some repetitively scheduled routines will not be completed prior the start of the next computation cycle. The computer then generates a software restart and displays an Executive overflow alarm." End of quote. Now tell me: 1) Why would the engineers have provided a radar mode which was causing a problem that they perfectly knew that it would happen (and which was not happening when the radar mode commutator was on the LGC position)? 2) Why would engineers have made the processor count itself the radar pulses when, in all other systems, including the one of the Saturn rocket, these pulses are counted by electronic counters instead and never, NEVER, by the processor itself; for, if these unwanted parasite pulses had been counted by electronic counters, the processor would just have read the count of pulses on the electronic counters (like all other systems do, and the AGC had an instruction allowing it to do it), and could have seen that the count of pulses was too high; it would not have had to restart, it would just have issued an alarm that the radar mode was on the wrong position.

And no, there was no program to make the lunar module automatically land, the final program, P67, was entirely manual (the previous program P66, was semi automatic, which means that it was the AGC which was controlling the main engine, while the astronaut was controlling the RCS). And, while it was up to the astronauts to shut off the engine when they were seeing the contact light (activated by the contact of the lunar probes with the lunar ground), it could also have been automatically made by the AGC, for the LGC could also automatically shut off the main engine. It would have been much safer if the landing had been entirely automatically made, including shutting off the engine upon detection of the lunar probes. Armstrong shut off the descent engine as the lunar module was already resting on the lunar ground. In Apollo 15, the engine's nozzle touched the lunar ground because of the way it landed, and it would have been catastrophic if the engine would still have been firing at touchdown, but Scott shut if off before the touchdown; if Scott had been as slow as Armstrong to shut off the engine, it would have ended in a catastrophy. If the landing was automatically made, this scenario would be sure not to happen!

The technique of the way points was completely absurd; it takes time to save data at regular points, it contributes to overload the computer, and it also contributes to reduce the available memory, and it is completely useless; the program could resume from the point it had been interrupted, with the current data, after having released the memory resources it had become short of.
