Hi Tony,
Thanks for the reply.
The drive is a Micropolis 1303, and I think it has
failed. The
drive does spin down after a minute or so.
I noticed the PERQ manuals do state that the hard disk
must
be able to perform a "locate disk heads" operation,
even
for a floppy boot - which I assume means find track 0.
Hence
I'm unable to boot from floppy.
I will check the signal levels just to be sure.
Wondering where to go from here. I'm guessing I could
buy a
replacement 1303 drive - but they are not cheap (hence
my
other posting) just to try and see.
Ian.
