I know a place that was using PDP-11's running RSTS long after most people thought the PDP was long dead. Don't know if they still are, but I kinda doubt it. But I can definitely say that if RSTS ran on faster/bigger hardware than a PDP-11 they probably would never have had a reason to leave it. bill -- Bill Gunshannon | de-moc-ra-cy (di mok' ra see) n.
