While there does indeed seem to be a limitation on 1024 cylinders,
the 3B2 is happy to use up to sixteen heads (indeed, the stock CDC
drives that ship from AT&T have nine heads).  Congruent Technologies
appears to have found a way to format a drive with > 1024 cylinders,
but we've not been able to do so.

The formatting utilities, called `idtools' (previously `devtools'),
are available in the 3B2 Maintenance Reference Manual, and it is well
worth the ~~$60 from AT&T.  Send mail if you want the info.
