That was before I ran into RSX-11. It's amazing how much more cojones a PDP-11 has with the right software. Too bad RSX-11 is such a poor programming environment (albeit better than \most/ real-time systems).

I'm working on it. Anyone have any ideas? The Software Tools VOS seems like a good starting point.
