They look too small to be Qbus and the module numbers are all 3
digits, whereas all the Qbus and UNIBUS module board numbers I've seen
had 4 digits.
this looks like an I/O module from the vintage of pdp 8/I or earlier
8's. the poster put in Qbus
to get more Dec types to hit the auction, rather than having any idea
what the unit actually did.
Note that the unit probably had all the modules pulled and they look
like they were put
back in sorted for pretty color rather than where they need to be. So
w/o drawings this
is a nice backplane and a lot of boards.
