This is the flight software used in the Gemini spacecraft (1960s).
The actual assembly code did not survive. It was considered sort of incidental. For the designers and coders then, the flowcharts were the program, the real source.
Wow, that diagram is absolutely wild! Thanks for sharing. Handwritten flowcharts and most of the code is actually math formulas and matrix computations.
