Installing Wren VII on Sun

[Matti Jokinen]

I am looking for instructions on installing a CDC Wren VII 94601-12G disk
on a Sun-4 running SunOS 4.0.3.  Especially, I would like to know how to
write the entries in /etc/format.dat.  Wren VII has an unusual geometry:
bit density is constant and the number of sectors per track is variable.
I wonder if it really is possible to get optimal performance under SunOS.
