It was envisaged as a computer utility, a machine that would support hundreds of simultaneous timesharing users. ...

... and Bell Labs withdrew from the project in 1969 as did General Electric, dropping out of the computer business altogether. One of the Bell Labs researchers (Ken Thompson) then decided to rewrite a stripped down version of MULTICS, initially as a hobby. He used a PDP-7 minicomputer that no was using and wrote the code in assembly. It was initially a stripped down, single user version of MULTICS but Thompson actually got the system to work and one of his colleagues jokingly called it UNICS (U ...
