seen another 8" drive that size.
Always something to learn!

Here's a strange one: I recently acquired
two Shugart 851 drives from
another cctech-er. They were in nice shape and operate fine. The weird
part is their form-factor.
I have 8 or 10 other 8" drives in my collection, both half-height and
full-height, including two other 851 Shugarts. All of these are 8.5" wide,
with faceplate and frame being exactly the same size.
These two "new" Shugart units are _9.5"_ wide at the faceplate and require
a clearance of about 9-1/8" for the frame. Can anyone explain this odd
sizing? Were they perhaps manufactured against an earlier standard?
IIRC, the "R" suffix drives are intended to be rack-mounted in pairs. I have
no idea, though, how that could be better than using the standard-width
drives since either way they're going to need some mounting hardware.
