A bit offtopic but I recently saw a surprisingly interesting talk about the Apollo board computer[0], and it's incredible how carefully they engineered the whole thing. Software hardcoded in the wiring, error correction for every memory access, ability to restart the whole system in any situation without losing state...this thing might have been rudimentary in today's standards, but the quality of the software was a different beast.
