	It's the only card that I have, but yes I would definetely be
willing to loan it out to get it working with NetBSD.

	I've seen references to a driver for the card for A/UX lying around
on various websites before, mainly newsgroup archives, but I've never found
the actual drivers. I have the MacOS drivers though, but not any of the
documentation. I've played with the card a little, but never used it
extensively, since I don't have alot of serial devices, and all of my
machines are already hooked up to my ethernet hub. But if this card really
IS capable of DMA it'd be great for a small dialup server.

	Speaking of DMA, might figuring out the DMA on the card's serial
controllers help a little with getting serial DMA working on the Q9x0
machines, once we totally figure out the IOP's?

	If you do want to borrow it for awhile just let me know. I can get
some packaging and ship it out ASAP. Maybe by the time it's supported I'll
be able to put it in my working Q900 system. :-)

	Thanks,

	Ryan
