JOSS
From Computer History Wiki
JOSS — JOHNNIAC Open Shop System — was a timesharing system created at RAND Corporation. Users interacted with the system using an interactive programming language vaguely similar to BASIC. The first version ran on the JOHNNIAC computer. The next, JOSS II, ran on a PDP-6. There was a less successful JOSS III running on an IBM System/370.
