I just noticed this discussion thread...  The probing algorithm is quite
simple, and data driven.  I wrote a tool that mimics the CONFIG part of
VMS SYSGEN, in order to configure my Q-bus systems according to DEC
rules.  By far most of the work was in copying out the tables of device
specifications from the Grey Wall.  :)

A write-up, and the tool, are at https://www.hamartun.priv.no/sysgen.html
