in the GOOD OL' DAYS of computing, a
game known as DOOM came out. and in the earliest versions, a screen that says "DOOM Operating System v1.
1", and that's nothing more than a screen. It's initials are the same as it's Operating System (
MS-DOS) witch stands for Disk Operating System.
Guy
1: Hey, do you remember seeing something that said DOOM Operating System v1.
1?
Guy 2: You mean, you saw something that said DOS?
Guy
1: No, boot-up an early version of Doom, and you'll se it.
Guy 2: Oh, alright. Ill do that later.
