Codename Tortilla(1988)
Universe OS 1990’s codename continued the trend of Universe OS 2.0 and Universe OS 2.1 being named after bread. The current name is Tortilla. The first leaked build 3.0.1, introduced quick bootup without DOS. The second leaked build 3.0.16 had a new boot screen and no longer needed DOS. The third leaked build 2.2.9 was a fork from Universe OS 2.1. It was supposed to be a test of a 32-bit operating system. The fourth build, Project Earth 2.2.11 became more stable with 32-bit computers. It also added features from 3.0.1 and 3.0.16.
