Yep, it's in a BA23 with a ridiculously dense Q-Bus. I considered  
installing the KZQSA from the 4000 in the 3200, but the edge connectors  
won't fit even after removing the panel, plus I read in the list archives  
that the 3200 won't boot from it. :^(

There's a QDSS as you point out, but I haven't tested it yet; need a  
splitter cable and one of those elusive VSXXX mice. Do have an LK201  
knocking about tho.

Wasn't aware the XXDP diags run on a PDP...
