Known restrictions:

	IEHDASDR doesn't support 3380s

	3380-K not currently supported (too many tracks/device):
		2655 cyls/device = 39825 tracks/device
		fails in allocation.

		<FLASH> Volker tells me that the Hercules CVS version 
		contains a fix to the problem he earlier reported regarding
		3380-Ks catalogs.  As I recall, this was within the context
		of usercatalogs.

	3390-9 not currently supported (too many tracks/device)

Untested:

	Creating 3380 sysres
	Using SYS1.LOGREC on 3380
	Master catalog on 3380 (possibly broken, due to suspected
		problem with creating mastercatalog pointer in 
		SYS1.NUCLEUS -- sysgen macro deficiency?).
	Page datasets on 3380

	works		Volker Bandke reports VSAM catalog on 3380 works ok.

	fails		Jay Moseley reports IEHDASDR with 3380s fails.
			At this point, neither Jay nor I are working on fixing
			this, and it's pretty likely we won't ever get to it.
			This is a perfect opportunity for someone who wants 
			to dig into it. <hint>
