I thought this too. But then realised it makes not much sense. Because with Concurrent CP/M you are supposed for example to dispatch a print job while doing other things. Thus assuming you would only use one physical console. If you needed additional terminals back in the day that would circumcise the idea of multitasking. For example there is OS-9 <https://news-commentaries.blogspot.com/2018/02/os-9-forgotten-operating-system.html>. There, just like with UNIX or Linux, you can dispatch a task by adding a "&" at the end of a command. I would have assumes Concurrent CP/M knows a similar procedure. -- Andreas You know you are a redneck if people hunt in your front yard.
