"MUSIC/SP (Multi-User System for Interactive Computing/System Product; originally \"McGill University System for Interactive Computing\") was developed at McGill University in the 1970s from an early IBM time-sharing system called RAX (Remote Access Computing System). The system ran on IBM S/360, S/370, and 4300-series mainframe hardware, and offered novel features (for the time) such as file access control and data compression."@en . . .
