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 kind of miss QIO$.

Those small systems *are* often PDP-11s, in this industry.

I'm working on it. Anyone have any ideas? The Software Tools VOS seems
like a good starting point. I found it real handy on those same PDP-11s
running RSX.
