This all makes sense - if one can reach into the CPU, it's definitely
plausible to have an upgrade which expands the size of the PARs (unlike the

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).
