#SCSI Help
3 messages in this thread
I'm looking for information on the SCSI interface. I need
technical data on the format of the hardware interface. IE: What are the
lines, what do they do, and what needs to be where, when. If info is
here, WHERE? If not here, WHERE? Thanks in advance for any and all help.

Ask for standards X3.131-1986 and X3T9.2 and the Common Command Set
supplement.
Even better, you might call the SCSI BBS, which is run by NCR employees.
1-316-636-8700, 24 hrs., 3/12/2400 8N1. They have tons of files on the
SCSI-1 and SCSI-2 standards. Most of the files are ZIPed WordStar files,
but can be extracted using the ZIP utility that resides here (somewhere).
Then, the files will need to be cleansed a bit (WordStar sets the high bit
in the last char of every word, so a simple AND $7f on each char will
cleanup the file enough that it is almost pure ASCII. Also, check out Byte
magazine. Feb+Mar of 90 is a two-part SCSI article, and Steve Ciarcia had a
two-part article on designing a SCSI interface based on the NCR 5380 chip
(same as is in several commercial Amiga interfaces, and same as is in the
Macs). That was May/June 86 Bytes.
Finally, one of the Fish disks had a file about building your own SCSI
interface, and you might want to track that down.
