I have an old 5400 sitting about languishing under Ultrix and I wondered 
if anybody was working on the Pmax port to it.  According to the web-page 
the port would be "trivial" when the Vax 3900 series was ported, which 
has since taken place.

I would be willing to work on it, however I am a student with rather 
limited programming experience.  I would be eager to do anything I could 
to facilitate the 5400 port.
