Back in 1984 I journeyed to Lexington, Mass and took a course at the DEC facility in Bedford (I think). It was a 2 or 3 day RT11 course, and was quite good. I remember bringing home a thick green book that was the guide for the student, I don't have it anymore; does anyone have one of these? The course I took was for RT11 V4, I wonder if there was a V5 course. Anyone take one of those DEC on site courses? I've never seen this type of DEC documentation offered for sale on ebay or anywhere. Maybe just rare? Doug
