Original CAD code in the wild?

Many moons ago, at Tektronix, I did a stint working in the Scientific Computer Center's Computer-Aided Design Development group. There was a software package, written in FORTRAN (77, I believe) on Tek's Control Data Cyber 73 system running KRONOS, called PIRATE. It was an automated circuit board placer/router. It would take in netlist information, along with information about board geometry and locations of fixed components, along with a library of component information (e.g., IC pinouts and packaging geometry), and generate Gerber photoplotter output, and NC drill tapes. The timeframe I was in the group was around 1977 to 1981 or so. I don't have any of that old code, sadly. But, I figured I'd mention it here, as perhaps maybe somewhere, someone has it. I remember that the first name of the guy that wrote it was Roger, but for the life of me, I can't remember his last name. I recall that Roger was brilliant, and was constantly tweaking the placement and maze-router algorithms to improve the placement and routing performance. It could do complex multi-layer boards, with internal vias, ground planes and power planes, etc. It would be cool if it could be found and archived. -Rick -- Rick Bensene The Old Calculator Museum http://oldcalculatormuseum.com
