Finally making mockups again.
Click Read More to see some of the "lore" behind the operating systems in here, not really sure if it counts as a spoiler or not.

BR-OS: 1901-1938
This was the first graphical operating system, invented by childhood friends Thomas Bennett and Hudson Robertson. They would soon become some of the richest men in Britain, creating a monopoly over computing. The operating system was patented, and other attempts to commercially sell an operating system were shut down by the Bennett-Robertson company.
IBM OS/AT: 1917-1985
In real life, IBM was founded in 1911. So in a world where operating systems were invented before then, IBM would get a head start, releasing OS/AT in 1917. Note that the Bennett-Robertson patent only applied to Great Britain, so IBM was free to create their own monopoly over North America.
Reich-Betriebssystem: 1937-1941
This is the operating system developed by the Nazi German government. Its development was stalled in 1943 when the tides of the war switched in the Allies' favour.
Codename Glasgow: 1942
This operating system was developed by the British government during the war. Notable computer scientists and mathematicians of the time worked on it, including Alan Turing and Max Newman. "Codename Glasgow" was eventually developed into Union Jack OS at the end of the decade.
Union Jack OS: 1949-1985
In 1949, Thomas Bennett died, 18 months after Hudson Robertson. It was decided that the patent of the operating held by the Bennett family was unfair, and thus it was lifted. Union Jack OS was released later that year. Until Acorn's RISC OS, it was the dominant operating system used in Great Britain.
EurOS: 1951-1987
EurOS was an operating system created in Germany, initially written off the codebase of the Reich-Betriebssystem. It was advertised as being a European operating system, hence the name. It slowly died out in the 1980s as American systems like Amiga, Mac and Windows were imported to the continent.
AmigaOS: 1970-Present
Commodore International was founded in 1958, so they managed to develop their operating system earlier. AmigaOS was instantly a success, and eventually IBM's monopoly over American operating systems declined. AmigaOS success lead to Commodore International not going bankrupt, and still being a major competitor to Microsoft and Apple in the present. However, AmigaOS has been on the decline since 2000.
Mac OS: 1980-Present
Apple would be able to develop their first graphical OS earlier, releasing the Macintosh in 1980. Mac OS would quickly replace OS/AT as the second most used operating system in America by 1987, and in 2002 it would replace AmigaOS as the OS with the most market shares. Mac OS today is still the most used operating system in the world.
Windows: 1981-Present
Like Apple, Microsoft would be able to work on Windows much earlier. 1.00 would be released in 1981, however initially it would not be able to compete with the success of AmigaOS and Mac OS, and after many disaggreements, Paul Allen would split from Microsoft in 1983, forming Omega Computers Ltd.
Windows would decline throughout the 90s, until in 1997 Apple CEO Steve Jobs invested $150 million USD into Microsoft. Microsoft would buy Omega Computers, and Paul Allen would return to Microsoft.
Today, Windows is the second most used operating system.
Arthur/RISC OS: 1984-1996
it's 1:19 AM. I'll finish this off eventually.
