Alan,
Yes…the 3000's SCSI port has been described as "flakey" and
there's even been once instance that I know about where the TPWR diode was
installed backwards.
In that case…the story is told (no idea of the truth of it) that
the engineer who made the schematic was known for drawing diodes backwards.
So when they got the schematic…someone reversed the diode in
production…presuming that the engineer pulled his usual trick. Problem
was…the engineer drew it right the first time.
There's also been several reports of compatability problems with
drives that work fine on other machines…or with other host adapters.
Short of dumping the 3000, or buying CBM's tape unit…adding a 2nd
host adapter seems the best way to go.
However, before you do that…please do make sure your tape drive
is properly configured …that is SCSI ID jumpers properly set and
terminator properly installed or not installed depending on what else is on
the SCSI bus.
