Gents, thanks for the quick update. Just got done watching about 4 of TheTechKnight's Youtube videos on resolving SE/30 problems to see if I could learn more. He also had a SCSi problem and traced it
to a similar cause (bad connection, not bad chip). This gives me hope that my board can be fixed without having to replace the chip (bigger task than I care to take on). I downloaded the Z53C80 doc
(thanks, Trag) and assume the pinouts are the same as for the NCR 53C80, but don't have a schematic for the board. Consequently, it's still difficult to verify the connections. Anyone know where I can find a copy of the SE/30 schematic? SCSIProbe is reporting that the SCSI bus is not terminated so I believe my problem is not identical to either zuiko21's or TheTechKnigts, but I think it's likely just a different connection that's broken.
