I once asked a CDC customer service engineer about this. He verified the
suspicion: the older CDC 9772 disk drives do not support specification of
the high order cylinder address bit during cylinder select (aka "tag-1")
using the "tag-4" signal line. The Xylogics 753 cannot address the last
40 cylinders on these drives.
