I'm not sure where I should start asking, so I'm starting here ;-)
I have a problem reading TK70 (and probably TK50) tapes in NetBSD 3.0 on a
MicroVAX II. There is absolutely no way of reading a single tape block
with a simple read(). All I get is
mt0: unknown opcode 0x80 status 0xc01 ignore

Hi Christian,
Have you asked this question on the port-vax netbsd mailing list? Also you're
on on Rel3, which is pretty old - I assume you have a good reason to be at
that release level, Have you tried booting a newer release and see if the
behavior is the same? I know, not exactly a convenie

Ok, I was fishing deep in the TMSCP protocol manual, and after fiddling
with the MSCP driver I found out that Opcode 0x80 (OP.END) alone (page
A-2) means MSCP protocol
