In addition to a broken TK70, which is being recognised fine by
NetBSD as mt0, I want to use a 40/80GB DLT on a Dilog SQ703 SCSI

NetBSD doesn't recognise it on booting.=C2=A0 I don't see anything
about addressing in the hardware wiki, does anybody know the address
where NetBSD looks for a second controller?
As far as I can tell, it doesn't.  The only TMSCP device I see is

mtc*            at uba? csr 0174500     # Tape MSCP ctlr

Since there's no other mtc in sight, I rather wonder why it's mtc*
rather than mtc0 - perhaps for machines with multiple buses?
Maybe its to allow you to define mtc0 at an alternate address and then
include GENERIC (for those who want to mess with the head of anyone
trying to match physical hardware to mtc device number :-p)

(Also congratulates Nigel for getting the uVAX II up and running! Do
you have the full 17^W16MB of memory? :)

Right now, just 12.  I have to make up a four-way cable to put in the third 4mB board! It's slow as molasses in January!
