Device driver compatibility BSD <==> Ultrix

[bruce nelson]

We are contemplating purchase of a display device for which we will be
able to obtain a working device driver for 4.3BSD on a VAX 750. However,
the machine we want to put the device on is a MicroVax under Ultrix.

What will it take to convert the device driver? Is it an easy (change
a few register locations) or hard (re-write the whole thing) type of 
conversion. there's also the question of Unibus vs Qbus and what changes
that would generate.
