Universe OS 1.0 was the first Universe OS. It could run without Universe DOS, as it was not an OS of its own.

Project Space(1983)
The codename of Universe OS 1.0 was Project Space, it was a plan to combine good ideas that weren't used in the final release of Universe DOS Shell(such as Windows) because it did not fit in the DOS as a program. The first leaked build was Universe DOS 4.0.226, and this build was in Universe DOS instead of a program. The second leaked build was Project Space 1.0.2, it had mouse support as well as a keyboard. The third leaked build was 1.0.11, it had more feature such as a wallpaper and a quickbar.
