About the best you can do with a PDP-11, even a
fairly "modern" one like a
11/73, is to use console ODT to see if the device CSRs respond. I've never
seen a PDP-11 microcode or boot ROM with anything even close to "SHOW
DEVICE".

Actually, the quad wide board QBUS based 11 (53 (?), some 73, 83, 84,
93, 94) boot roms do have the Map command that does a pretty good job
of listing the addresses that are readable.
