In august 1985 ther was a PCB program posted to net.sources. I have not implemented the program so I do not know if it is GOOD program. I enclose a copy of the advertisement for the program. Sven-Ove Westberg Lulea University of Technology Computer Aided Analysis and Design S-951 87 Lulea, Sweden Tel: 46-920-91677 Telex: 80447 LuHS UUCP: {decvax,philabs,seismo}!mcvax!enea!luthcad!sow PCB is an integrated router and editor to design printed circuits boards. It adopts the 'correct by construction' principle, that is it will enforce a certain set of design rules (such as cooper traces have to maintain a minimal separation, holes have to be aligned etc). PCB maintains a data base of the desired circuit to insure that signals of different net cannot be shorted, to keep track of unfinished nets, to support the routers etc. PCB V1.24 features: * Interactive layout editing functions with on-the-fly design rule checking and enforcement. * Interactive placement functions. * Integrated routers that can be used interactively or automatically. (Completion rates of >90% were achieved on a board with about 1.9 14 pin DIP chips / square inch) * Functions to move, shorten or straighten wires. * Supports the MOSIS process for 4 layer PC boards. * Update functions to allow changes to the circuit data base without re-routing the entire board. * Support for externally supplied geometry (such as connectors, text strings, logos etc). * Multiple wire widths. * Caltech Intermediate Form (CIF V2) output generator. * Versatec Plotter output for previews. Required input files: * A list of device descriptions. * A list of used devices with optional placement information. * A net list of the desired circuit. Required hardware: * A VAX running Unix 4.1 BSD * An unmodified AED-512 graphic terminal with a Bitpad-1 graphic tablet and a 4 key mouse. * (optional) A Versatec V-80 plotter PCB is written in 'C' and it might be possible to port it to other system configurations. It was successfully ported to 4.2 systems with a different graphic hardware, however doing so requires some hacking. A manual is included that gives some hints on how to port PCB. The CIF output format is probably unpopular execpt for people with MOSIS/Arpa connections. It is defined in the Mead & Conway book on VLSI systems and PCB uses only a few constructs of it. In other words, it should be easy to change the post-processor to produce other output formats (I'm interested in any such code). Please send me a message with your e-mail address if you use PCB. This is because of curiousity and to have a way to send out bug-fixes. Andreas Nowatzyk ARPA net: agn@cmu-cs-vlsi.arpa usenet: ...!seismo!cmu-cs-vlsi!agn

I am also interested in the program. Could someone send the sources to me too?

Prefer (but not a must), something that would work with a Bauch & Lomb
( AKA Huston Insturments) DMP- 29 eight pen plotter, or HP 7474(?).

Kick the habit: ask the American Lung Association about their
"Freedom From Smoking" class. It worked for me, the wife, and 75%
of the class. What a differance! Its GREAT!
