Vanura -∞

Vanura -∞ was created by Oggosoft, The first-ever computer company in existence.

Info
Vanura is the very first OS in existence. It was released before the big bang in 13800000000BC.

Storage
It contains 250 bytes of storage, and its use was very, very limited at that time.

(Yeah. it doesn't make sense but, does everything here exist and make any sense?)

Bugs
It has over 1 billion flaws in the computer itself, which is a very usual thing that happens for the first computer ever. Mostly, the computer will crashes after a couple of milliseconds after it boots up.
