The unix ``bigot'' in question recalls that the original Uvax II support
for 4.3bsd was contributed by (I think) mt.Xinu, and was in the archives
of postings to comp.bugs.4bsd at (I think) ucbarpa.berkeley.edu. Amongst
other things (mostly support for the KA650 cache, and emulation
code for the missing string instructions that acutally *worked*),
it included a Uvax booblock and a tk50 bootstrap, which the sufficently
perverse could probably build and put onto tk50 media.  (One really
doesn't want to overwrite one's bootblocks until one is *sure* the new
BSD kernel is going to boot.)  Having a functional Ultrix system with
TK50 media would be a *big* help there; though there's an existence
proof that it's not strictly necessary.

A replacement for the missing memory management code is probably harder;
though in a previous post, Paul Vixie threatened to have some working
about now...
