I'm not sure if this is the right place for it, since this isn't a technical post.
If not, please excuse me.
I'm personally interested in the history behind Process Simulate, and mainly Robcad.
But is dificult to find links or other kinds of material that cover this topic.
If someone here have brochures, manuals or even screenshots from older versions of theese tools and could share this material with me, I would really appreciate
