It sounds like a BA23, the DEC standard 8-slot Q-bus chassis.

Q-bus CPU's can be anything from a PDP-11/03 up to a Microvax,
and even some third-party CPU's with odd things like 68000's
and Z80's on them. You really gotta look in the CPU box and
find the CPU board to determine what it is. The badge on the
front of the BA23 may bear no relation to what's installed in
it.
If it is an -11, it's very likely an 11/73, /83 or 11/93,
possibly a 11/23.
