...But all the OS's on here ARE GUI's. There's no denying it... an operating system is an incredibly complex and low-level piece of software which creates an interface for the hardware through system calls. Operating systems made on Petit Computer do no such thing, so they're mostly just GUI's or collections of games.

Sorry.
