Very close. The first character is the processor type it's intended for,
the next two are the device mnemonic (not always the same as the mnemonics
used elsewhere, alas), then diagnostic "number" (you know what I mean :-))
and then revision and patch level, as you said.
I can't help with the specifics of most diagnostics (my microfiche set is
neither complete nor very accessible at the moment -- wasn't most of that
stuff on-line inside DEC once? What became of STARS and TIMA?) but you
might find the general stuff at
http://www.dunnington.u-net.com/public/XXDP.ps helpful (there's a .pdf
equivalent there too, thanks to the assistance of another list member).
