I have a version of the Racal Redac CAD system for the HP 2647 or 2648 graphic 
terminal I believe. Several DC 100 tapes and one or two boards full of custom 
ROMs... No documentation. I have not tried to do anything with it yet.

I wonder if that's what DEC used internally?  I remember some PDP15 systems 
around Merrimack NH that I was told were used for that.  They had big displays, 
VS60 tubes or similar.
