	The mt02 enables the tape drive to 'emulate' a real SCSI tape,
	so from NetBSD's viewpoint it is just a generic SCSI tape drive.
	The quality of the emulation is probably a little poor. :/

	You should still be able to netboot it. Thats not to say that
	fixing the support for the mt02 would be a bad thing!

	There is no specific mt02 support of which I am aware.
	What do the probe messages on NetBSD/sparc and NetBSD/sun3
	have to say about the tape?

	You should be able to hook up any SCSI device to that controller,
	providing NetBSD can recognise it. That would include DAT, DLT,
	scanner, zip, jaz, cdroms, and tape changers :)

	I used to run it a 4/370 and 4/260, but I had to leave all of
	them behind when I moved from UK to US :/
