Is there a list of SCSI commands documented anywhere? If it makes a difference, I'm using an Apple SCSI hard drive (made by Quantum/Mirror). --- Subash Shankar Honeywell Systems & Research Center voice: (612) 782 7558 US Snail: 3660 Technology Dr., Minneapolis, MN 55418 shankar@src.honeywell.com srcsip!shankar

(The number you gave is the committee document number.) While I am spending network bandwidth, I should also mention that electronic versions of the SCSI-1 and draft SCSI-2 standards are available on the SCSI BBS at (316)-636-8700. These documents are stored in ZIP format and contain WordStar (tm) files. The SCSI-1 files are actually revision 17B, which was the final approved committee draft document -- it is not identical to the ANSI standard, but should be technically equivalent. The SCSI-2 files are for revision 10b, which is currently in a public review and comment period. To avoid the usual series of questions: No, these files are not available for anonymous FTP (whatever that is :-). If someone wants to make them available for anonymous FTP, I'll be glad to cooperate -- I don't have the resources/knowledge... -- John Lohmeyer J.Lohmeyer@Wichita.NCR.COM NCR Corp. uunet!ncrlnk!ncrwic!entec!jlohmeye 3718 N.

There are a couple of documents which in describe SCSI (commands & interface)
in gross detail. They are :
COMMON COMMAND SET (CCS) of the Small Computer System Interface (SCSI)
X3T9.2/85-52 Rev 4.B (Is there a new revision???)
and
American National Standard for information systems - small
computer system interface (SCSI)
ANSI X3.131-1986
Both of these are ANSI documents. I haven't found them real useful from a
software standpoint. Much more useful has been just the manuals for the
particular SCSI device you are interested in. They tell which SCSI commands
that device supports and usually gives an overview of SCSI.

Well, almost. The first, CCS, is not an ANSI standard. Its not even an ANSI document (whatever that is?). CCS is (more like was) a working document of the X3T9.2 task group of ANSI-accredited standards committee, X3. (If that sounds like lawyer talk -- it is.) Groups like X3 are accredited by ANSI, but are not part of ANSI. Anyway, many SCSI products were designed to both documents, but CCS does not have any real status as a standard. I would recommend using SCSI-2 for new product design -- at least it is in the approval process to become an ANSI standard. SCSI-2 includes all of the worthwhile concepts from CCS plus many more useful features. The official designation for SCSI-2 is X3.131-198x. It will replace SCSI-1 upon its approval. Note that the 198x should really be 199x as the earliest that SCSI-2 will be approved is 1990. All three of these documents can be purchased from Global Engineering Documents at (800) 854-7179. They know these documents as: SCSI-1 X3.131-1986 CCS CCS SCSI-2 X3.131-198x These documents (except CCS) are available on the SCSI BBS (316-636-8700) in electronic format (ZIP'd WordStar files). >I haven't found them real useful from a >software standpoint.

While I would agree that the standards are not as easy to read as a device manual, be careful that you do not write your software so that it only works with that vendor's product. This is exactly how Apple got in trouble with the early MACs. -- John Lohmeyer J.Lohmeyer@Wichita.NCR.COM NCR Corp. uunet!ncrlnk!ncrwic!entec!jlohmeye 3718 N. Rock Rd.
