then,
In the late 1960s i remember ICS, Daisy and Mentor systems that would do board layout. Rather expensive though, about %50K for the base workstation (often 2901 based) as much more for the software, another chunk $70k for the photo plotter (Gerber compatible). All plus an expensive person or two to drive it. And about $1k/month HW and SW maintenance contracts to keep it running. They did 4-layer and 6-layer boards or IC layouts with different and more expensive software.
My dad was a EE and got all the trade rags there were lots of ads.
