My HP 7908 (kindly donated last year by Steven Hirsch)
failed this weekend. Investigation reveals that it has
blown the 10A fuse in the +12V section of the power
supply and when I replaced the fuse it blew again -
but stayed up long enough for me to see that the
on-board diagnostics do at least begin to run and that
the disk itself begins to spin up. Rather than
continue to stuff fuses in it I need to identify the
root cause of the failure.
Recognizing that there could be 1000 reasons why that
12V line is being overtaxed, has anyone encountered a
similar issue ? Clutching at straws at this point, but
any pointers would be helpful. The service manual that
I have does not give any specific guidance on how to
deal with this.
What's irritating about this is that I had only
powered it up to boot an HP64000 to copy some disks.
Failing that, does anyone have a comparable CS/80 unit
they might be willing to part with ? Or parts from
another 7908 ?
Thanks,
Dave
