<Yeah, and how about we call this new bus "Unibus"  :-)

And yes to run qbus cards from the new bus we need the qniverter. ;)

Likely not unless the small company is the size of the ZK0 facility in 
southern NH.  In VAX land OS and CPU are tightly linked and relay on the 
a multitude of device interfaces that are sometime mroe complex than 
the VAX itself.
