I need three things:

	1) Pointers to titles of books on programming scsi devices AND sources
            where i can get those books!

	2) (related to above) A nice refrence sheet or file to tell me what
	   the various command bytes and parameters for scsi devices are

	3) The answer to why I am getting a scPhaseError when trying to read
            a block from my CMS 20 hard dr (i have two pieces of sample source              code that someone generously sent but they don't give the precise
	    values of the command bytes i need to send) I do a scsiget, then
            a scsiselect, scsiccmd,scsiread, scsicomplete. I am on a mac plus.
            Also, I am using pascal. How long is a reasonable delay before calling SCSIcomplete (my sample says 10) 

THANKS FOR ANY HELP!!!
