HELP!! I need to become a scsi expert fast!! I am a hardware type ( logic designer ) who recently has been thrown into the world of peripherials due to budget reductions. I am looking for books/articals/videos which will explain the scsi software protocols/messages from a top down ( start at the begining) type approach. I have no problem with the electrical interface/timing but all these registers, messages and pointers are as confusing as hell. Any information will be greatly appreciated, and will help keep my learning curve to a miminum. thanks in advance: john Kolber ( 216 ) 449-6700 X5201 Allen-Bradley Industrial Computer Group 747 Alpha Drive Highland Heights, Ohio 44143

I can't really help you there, Rusty Haddock's suggestion of the Byte article is probably a good one for that. But, since you need to become an expert, and because you're a hardware type, it may be most useful to go straight to the source: American National Standards Institute 1430 Broadway New York, NY 10018 Ask for the SCSI ANSI X3.131-1986 spec. Cost is $20. [This info is from a Mini-Micro Systems article, Feb 1987. The phone number isn't included, but you might want to call them first to make sure the price is still the same] Ron Hitchens hitchens@godzilla.cs.utexas.edu hitchens@ut-sally.uucp

Byte by Byte data transfer works fine, but DMA will not. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Michael S.

The ANSI phone number (sales) is (212) 642-4900. The price for X3.131-1986 is $25 plus shipping and handling. SCSI tutorial info is also available from Technology Forums (612) 934-1415 at considerably higher prices. The SCSI-2 draft standard (X3.131-198X) is available from Global Engineering Documents (714) 540-9870. There have been quite a few articles in such publications as Mini-Micro, EDN, Electronic Design, Byte, etc. over the last 4-5 years that would make good tutorials. John Lohmeyer NCR Corp.
