Thank you for all your help people! I still am having trouble finding the command bytes needed to cause scsi devices to do things. I know that the code for read is 8 and write is 10 but i need moreInformation. Could someone please send me a list of the commands and all of the info on the parameters each takes! Thanks! I would also appreciate pointers to where to obtain good books on the subject (besides the ANSI electrical specs!) Thanks in advance! --

I would like to read and write to a video buffer through its SCSI interface. Are there any software available which will allow me to do so? Also is there any good book on the subject? I am also willing to pay if somebody is interested in doing this for me. Thanks

Your best bet is is call your friendly Hard Disk retailer and as for a product manual. This has worked for me from both retailers and Segate (Seagate in the USA even sent me a manual!). Other manufacturers may call the book with SCSI commands something other than a "Product Manual", but ask and thou might receive. SCSI commands differ slightly from device to device. The other avenue is to mail mr SRC@SCUZZY.UUCP (Heiko Blume) who at one point mailed a very good article to comp.periphs.scsi. We only have it on paper here and we don't want to type it in :-( . Also, you might try to find a document describing the "Common Command Subset" which most devices should support. Happy SCSI'ing and try to avoid the "SEEK RECORD AND SCOUR DISK" command :-).
