To be honest, I believe that at the time I was writing graphics software for 
the Pro-350.  My ex was in VAXworks that did most of the field training for 
new VMS releases.  My 3rd hand knowledge of the issues is rather stale.

There have been a number of interesting projects over the years that for one 
reason or another never came to fruition and some that took multiple starts 
before someone could work out all the kinks.
