Well my recent (last night) experience suggests that what you remember is
true. I was refitting my BA123 with a CPU, 8Mb of PMI memory, my one-and-
only DEQNA and an RQDX3 and stuffed into it a bootable RD54 from a VS2000
that happens to have VMS 5.5 and some stuff to fire up a LAT server and
clustering. The startup bitched mightily about the presence of the DEQNA
and casual reading of the error messages seemed to tell me that VMS 5.5
cluster manager did *not* like it one bit.

Because the machine is standalone at the moment, I didn't pay much attention
to it all. Eventually, I do need to get something working with Qbus and
Ethernet (so I can begin to make physical backups of some 9 track tapes I
have sitting here). I'll have to either stuff a KDA50 in this beast and
use my MDA SDI<->ESDI box (dual 1.2Mb disks) or hang a couple of RD53s
off the RQDX3 and limit myself to one or two tapes at a time before shooting
them down the pipe.

Ah the good old days...
