It seems to me that now others are using proof by assertion.
My understanding of the goals of this project are to run it on as many
platforms as possible. So, the answer to the above possible issues are
to port NetBSD to PDP-8 and PDP-11.
If the goal is to support museum exhibits running their original OS, then
why don't we have COMPAT for every other variant (or buggy) implementation,
such as XINU, Ultrix, various insecure (Kent) flavors of IPsec?
There were millions of those IPsec boxen sold, as opposed to mere hundreds
or thousands of PDP- or Perkin-Elmer (my first port) or what-have-you....
I don't run 386bsd on my old 60 MHz Pentium anymore, either!
