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.

can still run Univac 1100 programs.
