Usagi Electric video Repairing a 1956 vacuum tube computer Bendix G15: https://www.youtube.com/watch?v=8P48899B1WA
Learning the details of the Bendix G15 system architecture leads me to believe this system allowed creating some beautifully optimized code. Or rather the opposite: Naive code would lead to massive delays due to the cyclic nature of the memory. Having to wait for data would lead to massive slowdowns if code/data wasn't aligned properly. Fun stuff! I bet some nerds got the kicks from making their manager's code run in 1/3 time.
Random tidbit from the https://en.wikipedia.org/wiki/Bendix_G-15 Wikipedia article:
Apparently Bendix G15 was the first computer Ken Thompson ever used.
