I would greatly appreciate RSTS for my Pro380 too if you would like to
share it....

For myself P/OS was never my thing... RSTS would be much nicer on this
box...

Speaking as an RSX fanatic - was P/OS every the right thing for anyone...???
Now, if I could get proper RSX on that machine...

          Ohhhhhhhhh, that one!   I remember that chip.   That was an "ie"
      (Intel Ethernet) in Sun parlance.   The "le" (Lance Ethernet) found on
      some machines was far preferable.   I had to write a driver for an Am7990
      for an embedded application a long time ago; I remember that wasn't too
      bad.   I've never really looked at the 82586 at the programming level; I
      just remembered not to try to put too much traffic through them when
      building networks of Sun machines. :)

          There's Linux support for it, for which source code is readily
      available, and I have some earlier Solaris source code which will have
      some code.   Maybe pick through that for some tricks.   But man that
      sounds dangerous, no access clash protection...ugh.

          That would be great...Thank you!
