- ams6110 13y agoNo the Cray OS would have preceded UNICOS. https://en.wikipedia.org/wiki/Cray_Operating_System https://en.wikipedia.org/wiki/Cray_Operating_System Also some customers developed their own operating systems. Note that systems like this also required a separate management computer to boot the mainframe and load the OS.
- beat 13y agoThere was more than one OS. Supercomputer manufacturers (not just Cray) were basically hardware companies, and operating systems were an afterthought. Software was written on other systems and loaded in from the outside. UNICOS was a regular System V Unix port, to give users the sort of rich experience of a modern operating system.
