I have purchased the ST --> SCSI host adapter and driver software from
Supra ~$200. I was able to connect an Adaptec SC4000 SCSI disk controller
and a Micropolis 1304 (40 meg) hard drive . Guess what ...........
IT worked first time !!

The Supra will work with the Xebec controllers also, I don't remember the
model numbers, but call Supra and they will tell you.

The software that comes with the package contains a head parking program,
a formating program (this program will look for bad sectors and map them out
if you select this option.), plus a boot program.  The documentation 
covers building a hard disk system, ex. wiring , power supply requirments, 
placement of boards and so on. And of course how to get it 
all running.


The Atari is limited to ~ 16 Meg partitions so I have two 15 meg and a 12
meg partitions. These are hard drive icons C D E.

The ST will not boot off the hard disk, but you can put a Auto folder on
your boot disks that has a program to mount the hard disk. This takes
approx. the same amount of time as normal boot, but the hard disk is up and
running. Its pretty wierd seeing 5 drive icons on the screen but the hard
drive I am running is bery bery fast. The drive has a 6ms track to track
seek and 30 ms average, and I am running a 4 us step.

Needless to say this a Hell of a system.

I am very pleased with the Supra adapter.
With a daisy chained 50 pin connector could you mayber hook up another 
SCSI device (Tape drive for instance ..... cross your fingers.)????
