[Aren't you hungry...?]

	Is there any general concensus about the best way to handle IO to slow
devices?  I have been thinking about building a board whose disk interface
has a sort of staging area of 4K or so and then tells the processor its
there and come get it... This would allow, for example, hard disk backup
which happened in bursts at memory to memory speed rather than memory to
disk speed.

	My plan is to put a separate processor and bus on the disk interfac
and connect these to the main bus through an IO port.  Any 
thoughts/suggestions?

P.S. if this is a repost, I'm sorry.  Forgot to sign my name to the first
one, but I cancelled it  before it left the local site, so hopefully it
won't go out.....?????
