I'm having a little philosophical discussion with myself here about whether something that can't run on an actual computer (as opposed to a VM) is in any meaningful sense an "operating system" at all.
Meanwhile I can definitely boot RiscOS on a Pi containing built-in apps with a 1987 copyright message in them. I mean I can't then really do anything with it, but it's still got Haiku beat.
