I've used newer Wangtek and Archive 250MB QIC SCSI drives on my
Sun-3/260 with NetBSD-1.2, and I now even have a 525MB Archive Viper
drive on my Sparc-2.

So far as SCSI devices go anything that's bus-compatible (i.e. is SCSI-2
narrow) and that works on *any* NetBSD system will work on a Sun-3
running NetBSD if you have an "si" host adapter.

Unfortunately nobody's written drivers for the MT-02 QIC-36 interface
adapters yet (not that there's been much call for them!).  It really
shouldn't be that hard -- the MT-02 appears to be a SCSI tape device,
but one with some weird brain damage and of very limited capabilities
(w.r.t. the SCSI commands it supports).  Basically an MT-02 manual and a
copy of the complete st driver should allow a knowledgable kernel hacker
to pare it down to work.
