I know the first is common knowledge, but not for I:

What's the diff between the Wren VII and the Wrenrunner? Right now we have a
bunch of Wren VI's; they've had a colorful life with us, but now that they're
older and more settled down (and we've culled out the flakey drives), they're
doing fine. Nice and fast too. But we're looking at buying some more big
drives, and I'd like to get the lowdown on the rest of the Wren line. (For
various political and other reasons, we're probably gonna stay Wren pern.)

Next: There's been some talk in the past on Suns and differential scsi (I
don't think it was here...) and possibly getting it enabled. Is this truly
possible? I've hacked a little code in the kernel and found the scsi_options
symbol, and found various include files, etc...and I've also heard that the
Wren drives are capable of diff scsi...and I'd like to put 1+1 together
and get some real throughput, but...has anyone done this? Does it work?
Is it possible even? Or am I just california dreamin'?

(My test bed: SS1 or 1+, 1xQuantum 105MB internal, 1xWren VI, 2xSun 150MB tape)

Thanks all.
