So the "old platform" was the National 32016 addon cards that somehow 
ran a Unix?

I'd love to learn more about that, I really liked the 320xx architecture,
seemed like a winner but my memory is they were buggy.  Still would like
to get some idea of what it was like to run on an XT/AT with that card
plugged in.  Did you boot DOS and that somehow booted Unix or what?
