Anybody know anything about these pups?  I just tried one in a 400s with a
selection of DIO cards:

98642A 4-port MUX	works
98625B HP-IB		ROM identifies and then "UNEXPECTED USE OF FFFFFFAC"
98658A SCSI		ROM identifies and then hangs

I get a Really Bad Feeling from this, it sounds like devices which do DMA
don't work.  The most comprehensive documentation I have seen on these
adapters is from a price quotation and says:

	"Converts DIO-II interface in Model 400s to DIO.
	Includes all hardware and instructions."

No documentation was included with any of the 6 adapters we received.
