XXDP help needed

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). -- Pete Peter Turnbull Dept. of Computer Science University of York
