Source code listings from REDAC PDP-based PCB layout system.

[CuriousMarc]

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.
