ultrix disktab entry for an RF73?

Thanks for the information

I found another solution as well. The old DSNlink database gave me the
total number of sectors on the RF73 and identified a RZ73 disk with the
same characteristics. On an old alpha at work was a disktab entry for a
RZ73. I was able to munge the RZ73 information into a RF73 disktab.

I was only interested in the C partition so the others may or may not be
valid:

rf73|RF73|DEC RF73 Winchester:\
       :ty=winchester:ns#71:nt#21:nc#2621:\
        :pa#131072:ba#8192:fa#1024:\
        :pb#262144:bb#4096:fb#1024:\
        :pc#3907911:bc#8192:fc#1024:\
        :pd#15884:bd#8192:fd#1024:\
        :pe#307200:be#8192:fe#1024:\
        :pf#542575:bf#8192:ff#1024:\
        :pg#291346:bg#8192:fg#1024:

And here it is mounted on /scratch
