[comp.sys.mac.hardware] death of a SCSI controller

kenney@hsi.UUCP (Brian Kenney) (03/15/90)

For all you intrepid folks who open the case on Mac SE's that have an
internal hard disk:  Be careful and make sure that the SCSI connection
is firmly seated in both sockets when you put it all back together.

Apparently, when I put mine together again, one end of the ribbon cable
was not making contact with the logic board.  Turned it back on and ...
nothing.   I opened it back up, spotted the error, and reseated the
connector.  Turned it back on and ... still nothing.  Apparently, I
toasted my SCSI chip on the logic board.  It'll boot from a floppy,
but not from any SCSI drive (I tried an external one, too).

The fix:  replace the logic board.  I got a quote for $350.  (Being the
pessimist, I expected at least $1000, so I was pleasantly surprised.)  

Moral: be bloody careful.  (Strange that a loose data cable would do that -
we used to mess up data cables on pcs all the time to no ill effect.)
