DEC B400X expansion chassis

OK, my neighbor just dumped a B400X expansion chassis on me (unfortunatly he's keeping the VAX 4000-100). Is the backplane straight Q-Bus? I'm wanting to see about stuffing a VAX 3400 boardset in there (that he also gave me). I'm assuming I can't stick something like a 4000-300 boardset in it (really don't know as I've not had access to something like that), or do they plug directly into the Q-Bus? Zane -- | Zane H.
