50,000 tracks = Mod 3
150,000 tracks = Mod 9
Figure out the rest from there.

We have an old TSO command call SPACE that gives a quick display of online
DASD, tape, and some other stuff. It reports a DASD device as 3390-xx
based on a table lookup using some data in the returned UCB. This command
never reports a device as bigger than a Mod-9 even though the capacity may
be several times that, e.g. Mod-27 or Mod-54 in common (though unofficial)
parlance. It appears that nothing in the UCB indicates Mod->9, so the
command may need to be modified to calculate a mythical model number based
cylinder capacity, which SPACE does report accurately. Any advice?
