    Quite understandable!

	I finally junked my 2090 in favor of the 2091, and lo, my Tandberg 150meg
(It seems only capable of running in a select/deselect environment) began to
function better.

	The 2091 driver however introduced a new problem, which trashed my
SCSI command block. Someone from CBM posted a partial scsidisk.h in 
comp.periphs.scsi. CBM added to the end of the SCSIcmd structure for auto sense
handling, which caused my data to get overwritten. This scsidisk.h is newer
than what appears in the 1.3 RKMs and what ships with the latest Amiga C
compilers, so beware. Also, a new flag was added to the SCSIcmd.Flags field.

	Can anybody shed any light on these flags, their use, etc.? There's no info
anywhere in the RKMs. 

	Does anyone have the new scsidisk.h? 

    That is, could it be posted? Diffs maybe?

	Any chance I can take you up on this offer Larry?

    I'll give it a spin, fix any problems, and send the fixes if any back to
you if you would like that.

	I'm basically stuck now, for some reason the 2091 hangs with the "activity"
LED on. This is a real bitch to debug. I was lucky to stumble on the SCSIcmd
being larger now than before, which gave me the weirdest SCSI status from
the tape drive (invalid command, due to my internal command block being
overwritten).
