OS that doesn't use Virtual Memory

What are some operating systems that didn't / don't use virtual memory?

Virtual memory was introduced to the x86 CPU architecture in the Intel 80286. So you'd need to find an OS (and hardware) that was pre Intel 286 days.

This sounds suspiciously like a homework question.

It's just a "challenge" question at the end of a chapter that I couldn't figure out. Not any kind of actual assignment.

From what I can tell the DOS/360 & OS/360 are a couple that wouldn't have had virtual memory at the time.
