I know I'm late to this discussion, but are you aware of this:


It's basically bank switched unibus memory.  Not split I&D, I know but 
might be interesting.  And not QBUS, I know.  But I thought I'd mention 
it, since at one point in the discussion I could swear there was talk of 
the 11/34 two board set.

I somehow ended up with a bunch of these boards, and some blanks and 
enough spares to finish some of the blanks.  If you are interested I'd 
be more than happy to "share".  I have a working 11/34 and 11/44 so I 
could even test them.  I think I might need to blow some PALs, but I can 
do that if I can find the right parts (gals, most likely these days).
