         A few months ago a file appeared on some BBS's describing someone
elses implementation of a SCSI controller for Ami. It was called AmScsi.arc.
It has a text description and a schematic. The implementation was quite
simple & (I believe) used a National Semiconductor part. If you can't find
it & are interested I will send it on to ABF20 (or whatever its called) the
replacement for Xanth. I would send it to you via mail but have difficulty
getting mail to UUCP sites to make it without bouncing.
	If you want the written specs on SCSI they are available as 
ANSI X3.131-1986 from the American National Standard for Information Systems,
1430 Broadway, New York, NY, 10018.
