So, you find yourself in some computer room, for some reason. Lots of computers, old and new. Why are you here? Who knows. Maybe these computers will give you an answer. Except all of them are locked, save for one. Impossible to get to them without breaking anything, and that's something you'd want to save for last.
Looks like this dusty old-school IBM PC is your starting point. You'll want to find how to unlock these computers, one by one. Each of them will give you the name/URL of the next one and their credentials, if any, behind a little puzzle. Each level features a full-featured emulator of a different operating system (ideally free, redistributable and lightweight, so no Windows
) running in your browser, so, needless to say, you'll want to know your way around Linux, DOS and operating systems in general.
Again, it's some idea I find pretty cool and educative and I'm not sure I'll work on it right away with my numerous other projects, but yeah, I want your feedback and ideas, what do you think about it?
