This sounds pretty good, but I have a couple of other questions:

	1.  How does such a board interface to the ST?  Does it fit
internally or plug into the DMA port and stick out the back?

	2.  What is the approximate cost?  Do you have to have both of the
above boards or are they combined?  Also, what are some good HDs that can
be used with an SCSI interface, such that the total cost of the board and
general SCSI drive would cost about the same as an Atari or Supra drive?

	3.  Since Atari markets a disk drive that plugs into the DMA port
and will hopefully fix the HD support in TOS soon (no more 40 folder, I hope),
will future software releases somehow not work with SCSI.  (Maybe this is
a naive question)

From what I've seen in Byte, there are a lot of HDs for the IBM that cost a
lot less than the $600+ currently charged for some type of drive for the
ST.  I hope this board can offer a few more options.
