Actually I should remember that one as well? I supported a Unisys mainframe, after I
worked with GCOS-8, though I spent most of my time with HP-UX and SunOS at that time.

z/OS runs on IBM Mainframes, there is also ?IBM
i?, which was previously called OS/400.
Last I checked, GCOS-8 is still running, but with Itanium end-of-life, I?m not sure what
on. It?s been a niche market for decades. I?d argue that it was a serious niche when I
was using it in the early 90?s.
It is amazing how many people - IBMers included - that simply do not
realize that Unisys exists, and both MCP and OS2200 are modern, up to
date operating systems running on quite a lot of sites in the real
world.
