RF74 Disk

[Andrew Ball <asbatwrk%gmail.com@localhost>]

I have looked at the 'RF Series Integrated Storage Element User Guide'
and was able to find a geometry for most of the DSSI disks. RF36 and
RF74 though mentioned different number of sectors per track for
different 'bands', which makes some sense given that outer tracks
would be longer. Since I'm making virtual disks for open-simh, I'm
probably just looking for a total number of sectors (especially for
the RF74). Could someone point me in the right direction?

Thanks,
