Early computers didn’t have operating systems.
You just plugged in a punch card or tape with the program you want to run and the computer executed those exact instructions and nothing else.
Those programs were specifically written for that exact hardware (not even for that model, but for that machine).
To boot up the computer, you had to put a number of switches into the correct position (0 or 1), to bring its registers in the correct state to accept programs.
So you were the BIOS and bootloader, and there was no need for an OS because the userspace programs told the CPU directly what bits to flip.
What would the other be
TempleOS
When you really have to look deep into god’s mind you just have to put templeOS on a supercomputer.
If you install TempleOS on the fastest supercomputer Frontier, you get Event Horizon.
WARNING: Gory, disturbing picture
Do NOT network-enable TempleOS.
God will get angry if you do.
What movie/tv show is this image from?
Event Horizon
Praise be upon him
a glowie’s worst nightmare
You mean the NA/Mixed category?
Probably mostly z/OS and BS2000.
Or actually a mix between Linux and Unix.

They ofcouse had one, probably linux, or unix. But that information, about the cluster, is not available.
Thanks for the links!
