I know that WECo used some DEC PDP systems in some of their interesting experimental work. Prime examples being the COSMIC automated system for managing MDFs. And I believe a PDP-8/e was used as an experimental replacement for the card translator of the #4A toll crossbars before the "proper" 4A-ETS came out (I think they also used an 8/e in managing Dimond ring translators). But that's beyond the scope of interesting non-mainstream minis. Cheers, Christian -- Christian M. Gauger-Cosgrove STCKON08DS0 Contact information available upon request.
