I'm curious about the origin of the directory name /usr/mdec. (I am reminded of it because I've noticed that it lives on in at least one of the BSDs.) I had a vague notion that it meant `DEC maintenance' but that seems a bit clumsy to describe a place holding boot blocks. A random web board suggests it meant `magnetic DECtape.' That's certainly not true by the time I came along, when it contained the master copy of the disk boot block(s). But I suppose it could have meant that early on and the name just carried forward. A quick skim of the V1-V7 manuals doesn't explain the name. Anyone have any clearer memories than I do? Doug or Ken or anyone who was there when it was coined, do you still recall?
