I am near positive I did not fry anything since everything is working correctly except a sustained write to the tape. If anything were damages, I would expect nothing to work at all. I have ordered the new scsi card and I will report back in to this thread when I find the results. I am also interested in using the sym53c8xx-2 driver instead of the older ones. The older drivers presently work the best with the present configuration. Perhaps the newer drivers do not tolerate the bad scsi chain as well as the older ones ?

Yes and no. From the SCSI FAQ: "[ANSI] specified that if an LVD device is designed properly, it can switch to S.E. [single-ended, i.e. "normal", SCSI] mode and operate with S.E. devices on the same bus segment." - http://h000625f788f5.ne.client2.attbi.com/scsi_faq/scsifaq.html#Generic099 So if you mix it with S.E., you lose its LVDness, e.g. you have to stick to a S.E. bus length; but you shouldn't fry any hardware. HVD (high-voltage differential, i.e. the original differential variant of SCSI) is another story completely! That is indeed flat-out incompatible with S.E. (and presumably with LVD too...) -- | | /\ |-_|/ > Eric Siegerman, Toronto, Ont.
