Oct 16, 2023 at 18:34 comment added PDP11 I worked for a company that sold an operating system by Microsoft for the Z80 processor with a wordprocessor written in BASIC. It was interpreted BASIC i.e. only BASIC and used hard sectored, 8 inch floppy disks.
Oct 16, 2023 at 17:58 comment added davidbak Answers are now diverging into minicomputers and others of early retro- era. So here's the obligatory mention of the ground-breaking IBM 5100 of which one-half of which was a BASIC-only machine, thus, yes, BASIC was its operating system. (The other half of the 5100 - depending on which direction you flipped the big toggle switch on the front - was an APL-only machine, thus, yes, APL was its operating system.)

Aug 2, 2020 at 16:33 comment added Solomon Slow A modern "operating system" fulfills several different roles, but IMO the most general thing one could say about operating systems over the entire history of computing is that is they are software components of computer systems that facilitate the use of the computer in more than one application. On the other hand, there is one class of operating system—namely, embedded, real-time operating systems—to which that definition does not apply at all.
Aug 2, 2020 at 16:33 comment added Jeffrey Henning Personally? 1) The ability to load and launch applications, regardless of the language they were developed in, 2) The primary UI for doing so (I realize it is often considered a separate program)
