Hmmmm, of course Sun supports this drive for the IPI controller but I
thought I'd just send it on in case it could help for a 753.  So I looked
in format.dat and lo there was no 9720-1230 on my 4/60. Odd. Anyway here's
one for a 9720 for the IPI.

disk_type = "CDC IPI 9720" \
	: ctlr = "ISP-80" \
	: ncyl = 1631 : acyl = 1 : pcyl = 1633 : nhead = 15 : nsect = 82 \
	: rpm = 3600 : bpt = 50400 : skew = 0 : precomp = 0

disk_type = "CDC IPI 9722" \
	: ctlr = "ISP-80" \
	: ncyl = 1630 : acyl = 1 : pcyl = 1632 : nhead = 7 : nsect = 156 \
	: rpm = 3600 : bpt = 100800 : skew = 0 : precomp = 0

What makes this interesting is the 9722 entry.  I'm still waiting for my
9722 but at least there's some hope.
