This work illustrates the machine code of the Luminary 1A (version 099), the Lunar Module's (LM) Apollo Guidance Computer (AGC) for Apollo 11. In the background the reentry capsule is shown. Two different variants exist:
The binary code is a part of the compiled (using the Docker image) Virtual Apollo Guidance Computer, where the generated binary has been dumped to binary format using xxd.
The original assembler source code for the Apollo 11 guidance computer has been transcribed (about 3000 pages!) and is available on Github, https://github.com/chrislgarry/Apollo-11.
The Futura font is the first font to land on the lunar surface, as it was used to engrave a plaque: HERE MEN FROM THE PLANET EARTH FIRST SET FOOT UPON THE MOON JULY 1969, A. D. WE CAME IN PEACE FOR ALL MANKIND - signed by the astronauts (Neil A. Armstrong, Michael Collins, Edwin E. Aldrin, Jr.) and president Richard Nixon. The plaque was mounted on the lunar landing vehicle which was left behind on the moon, see How Apollo 11 launched Futura to the moon for further reading.
In this work the Futura font is used for the title and description.
- 2048 words of RAM. A "word" was 15 bits of data—therefore just under 2 bytes (16 bits) of data—and so the total RAM was just 3840 bytes.
- 36,864 words of read-only memory, equivalent to 69,120 bytes.
- Maximum of about 85,000 CPU instructions executed per second.
- Dimensions: 24"×12.5"×6".
- Weight: 70.1 pounds.
- Power supply: 2.5A of current at 28V DC
Astronauts communicated with the AGC using a numeric display and keyboard called the DSKY (for "display and keyboard", pronounced "DIS-kee").
