For me, DEC was the first "real" computer that I could actually work on. Attending the Maynard training facility was a blast. The instructors used to have us practice troubleshooting the 11/45 by putting tape on a finger "somewhere", and then we had to find the fault. I still remember a friend and I going in one night to practice, putting a piece of tape on a random finger, and taking some two or three hours to find the "problem" :). Normally, the instructor faults would take us maybe 30 minutes max. Later, I programmed an 11/05 as necessary when looking for faults in the control system for a large bakery. T'was just plain fun!!!!!
