I would really like to get a description of the
jumpers.
The next level of detail might need to be the print set because I have a
spin up/down problem which is not the sticking heads problem, and if I get
desperate I might start using my newly acquired oscilloscope to see if I can
work out why it is happening. I think there are people on this list who have
fiche readers, but I don't know if it is possible to get machine readable
scans from fiche.
The spin up/down problem has only just started happening on one of my disks
and is quite odd. I have it in a MicroVAX 2000. When I have seen these
problems before the disk will spin up and down quite quickly, but in this
case the disk spins fine during the POST, but then when it gets to TEST 7
the test pauses for a while, then the disk slows down, at which point the
test prints its question mark, and then the disk speeds up again and the
Jumper W1 makes the drive latch the error, you may need to try that
the fault finding flow chart is replace board/whatever and retry
without much/any detail
POST continues, but the disk is seen as faulty and
that is that for the
disk. I have not seen this behaviour before.
