More than any other brand, it seems that DEC stuff
is dead simple to
service if you know how, and impossible if you're playing by ear.
All I can say to that is that I have never worked for DEC, and don't have
access to any 'internal failed circus' manuals...
In other words, _I_ had to 'play it by ear' the first time. And actually,
the RX01/2 is not that hard to work on (at least not compared to some of
the things I've had to sort out).
Incidentally, I suspect I'm one of the few people to trace RX01 problems
using a KM11 card (or actually a copy of same) plugged into the test
connector...
