Can you repair it, instead of replacing?
There are some double sided Sonys around (check with Tony?) with physical
head damage, but intact electronics.
It comes from an HP 1650B logic analyzer - does anyone
know if
it's a 600rpm or a standard 300rpm device?
not offhand
If it's a 600rpm then I've found
someone who has one but wants a lot for it, otherwise I'm reasonably sure I
can modify the cable connections to use a standard/modern drive.
Can you change the data transfer rate produced by the controller?
On the motherboard side, it has a Zilog Z0765A FDC,
and I've successfully
created disks on my PC (using HP's LIFUTIL) that worked on the drive. This
makes me think that the drive is a standard 300rpm. Any thoughts?
no.
600RPM at 500K data transfer rate (Sony) is the same format spec as 300RPM
at 250K data transfer rate (PC "720K" hardware)
