The Q-bus controller *did* exist (actually I think it was mostly the same
as the Unibus controller but with a different interface card), it was called
the RKV11D.  They're very rare (I sure don't have one), and they're horrible
in that they're actually *Q16* devices, bits 5:4 of the CSR don't really work.
I've heard there was an ECO to fix that and at least bring them up to Q18.

Older versions of the 11/93 (and probably others) boot ROMs had a bootstrap
for the RK05 (which almost no one had on Q-bus, certainly not on an 11/93),
but *not* for the TK50 (which everyone in their right mind has!).  I always
thought that was pretty funny.
