I think I still may have a copy of the Great Softwestern pcb layout addon for AutoCAD.
The first board I ever did on a computer was on AutoCAD Ver 1.x
I plotted it in ink at 2x to mylar and the pcb house worked from them.
Just my .02

IC gate-level design

I know several of you out there have microprocessor
development
environments from Intel and TI, IIRC. Ditto for things like PROM
programmers.
What about the design software? I imagine the first
generation of EDA
software was created in-house by pioneers of VLSI design. But what
about when the tools started to become commodities? What about early
releases of software from a company like Mentor Graphics?
