  I see on the usual site, an 11/23 box with a couple of

 one of which is an M7608 board.  This is a Microvax memory board.
 I wonder if one can build up a Microvax in that backplane, or if that is
 not recommended.  It would obviously be an 18 bit backplane.  The
 backplane is H9276A. 
That's a 22-bit backplane so I don't see why you couldn't build a
microVAX in it.  Bear in mind it's all straight QQ-CD, unlike BA23 and
BA123 backplanes normally used for microVAXen, which have serpentine
sections and can hold more cards.
