    At first glance this is just CMS, and doesn’t appear to include CP, which is a shame.

    CP (VM) was the hypervisor portion. CMS is a simple single-user operating system that ran on the virtualized hardware presented by CP. The older versions of CMS (like this one) could also theoretically run directly on the real hardware, but I don’t think anyone ever did outside of those who were developing CMS itself.
