oh, sweet naivete...  for better or worse atari's DMA and the industry-standard
SCSI interface are far from equivalent.  simply crossing a few wires won't do
it for you;  you need an adaptor board (not to mention a disk controller,
unless your disk is *really* a SCSI disk, i.e. has its own built-in
SCSI controller).
i'm familiar with two companies making DMA to SCSI adaptors for the ST:
Tech Specialties, in Houston, and Berkeley Microsystems, in Oakland CA.
I know essentially nothing about Tech Specialties, except that i think they
mostly do turnkey hard disk systems.  i have done business with berkeley
microsystem - i bought their adaptor, as well as an adaptek controller
board, from them.  i use mine to drive a quantum 540 HD.  i've had no
problems.
the cost on these two boards is approx $125 each.
for more info, see my article in the march "ST Applications" magazine
entitled "a hacker's hard disk", wherein i describe my experiences putting
together my disk system.  if you can't find a copy of that mag, send me
a sase and i'll send you a copy of the article (i could uucp the text, but
you'd be missing the graphics then).  i will be happy to do this for whoever
would like a copy.

[aside: i'm beginning to think that this newsgroup needs a "answers to commonly
asked questions" article posted periodically, like that posted with the
netiquette article.]

good luck!
