I'm not sure exactly what you want when you mean "similar", but all the RSX-11 DECUS SIG tapes are online at ftp://sunsite.unc.edu/pub/academic/computer-science/history/pdp-11/rsx/decu… You'll find the index to each SIG tape there, as well as the outputs of a few useful searches (like a search for all references to the MultiTasker newsletter.) If you want to know about industrial process control under RSX-11M, I can point you to a few good resources. Be prepared to pay between $100 and $200/hr for the experts. -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927
