Dear All, Both the README file in the documentation for chem.pic and https://www.troff.org/papers.html refer to the manual: "CHEM - A Program for Typesetting Chemical Diagrams: User Manual" by Jon L. Bentley, Lynn W. Jelinski and Brian W. Kernighan. Unfortunately, the URL http://cm.bell-labs.com/cm/cs/cstr/122.ps.gz is dead and redirects to some kind of VPN service.
I tried searches on archive.org but to no avail. Does anybody happen to have a copy at hand? Thank you, and best regards, Oliver. -- Dr. Oliver Corff mailto:oliver.co...@email.de
