  It seems to me that, if one can plug a particular board into a slot in
a particular machine, one should be able to do the same with simh,
regardless of what *old* code may or may not support it.  People are
writing new stuff for these machines all the time; witness BQT's IP
stack for RSX for example.

  I myself have multiple KS10 systems here, and would love to be able to
plug DEUNAs into their Unibus chassis at some point and have it actually
work.  DEUNA support in simh would surely be instrumental in allowing
that to happen.
