[comp.sys.apple] Disk ][ ribbon cables

mdavis@pro-sol.cts.COM (Morgan Davis) (11/18/87)

Sean Kamath is right on the mark with his statements about the ribbon cable
being a problem with some Apple Disk ][ drives.

I had two drives that went out on me and took them to a local dealer to have
them fixed (I didn't have the time to work on them myself).  I figured
(incorrectly), "The dealer's tech knows about these things.  He can fix 'em in
minutes."  I didn't hear from the tech for a week.

He calls and says one drive is fixed (a bad IC on the analog board -- I could
have guessed that one).  But he says, "The other drive is totally shot.  We
swapped out everything but the mechanical parts and it still failed.  You
probably don't want to pay to have a new stepper motor installed."  I didn't,
especially when he had the nerve to inform me that to fix one drive, and the
charge for labor on two drives, it would cost me $90 dollars!  NINETY!  You
can get a new drive for $75.

So I said, quite calmly to him, "Keep the good drive and the dead drive.  I'll
go buy a new one for $75 and save myself some money."  At which point we got
into a heated argument.  Apparently, he didn't realize that he was talking to
someone who actually knew a thing or two about computers.  I wonder just how
many people have been blindly ripped off this way...

Anyway, I haggled with the dealer until I got him down to a $35 repair charge
for both drives, then picked them up and brought 'em home.  Something didn't
seem right about "everything being swapped out but the mechanical parts and it
still didn't work" yet the stepper motor was working, albeit getting I/O
errors when reading a disk.  Hmmm....

The *first* thing I did was exactly what Sean Kamath described: hook up the
two drives, test them, then swap only the cables and test again.  Viola'. 
Suddenly my *good* drive was now getting errors.

The quick fix: remove the connector from the controller-end of the ribbon
cable, snip off about an inch of ribbon, then press the connector back on.
Works like a charm now.

Ninety dollars.  What a bunch of crooks.
