No this is a fixed disk with ~132 Mb capacity and a built in tape drive.
If you can get the schematics, or do some tracing, one thing that most of these will do
is
spin up w/o moving the heads. You can get this to happen by either physically pulling
a driver connector, or setting a switch to be sure the heads don't get energized.
That's a good idea. I'd been thinking of doing something like that.
I would get the drive to be able to spin up first w/o head load and be sure that it
is happy (finding a test manual would help a whole lot here).
Then be sure you get the media you plan to use cleaned. If you have a fixed disk,
you probably have a bigger problem than if you have removable, since you can
get in and clean the cartridge media and inspect it much easier than a fixed platter
in a drive.
Use lint free cleaning swabs and isopropyl alcohol for cleaning. I doubt there
are any media houses left in existance, but if there are, you could send the media
to them for a clean job and inspection.
I wish! I don't have the couple of grand that they'd want to do a job like
that. I'm on my own here.
Clean the heads off and inspect them as well before any power up.
Then all you need is luck and a quick hand on the power if you crash. these
drives can survive a crash with some luck if you are quick enough and don't fry
the head. Of course the media will be lost, but that is better than the whole
unit.
I don't care about the media, or the drive either for that matter. I'd like
to get it fired up ONE time just long enough to copy the OS to newer HP-IB drive.
Anybody know if these use the same tapes as the HP 9144/7942/7946? Also if the
9144/7942/7946s can read the 7914 tapes? The 7914 (and the 7942/7946) has the ability to
copy directly from the hard drive to the tape drive without being connected to a computer.
(The 9144 is a stand alone tape drive. The 7914/7942 and 7946 are all combination tape
drives and hard drives.) I thought it might be better to make a backup tape directly on
the 7914 rather than spending what be left of the 7914's limited life trying to get to
boot on the 1000 and figuring out the passwords, etc and the commands to copy the drive
contents to another drive.
