I've got an SA-4008 that I'm wondering
about--obviously the spindle
You mean the 14" one?
motor spins the platters up to speed, but the drive
doesn't come
ready (it did about 5 years ago when I last powered it). I'm
wondering if there's a stuck positioner issue on that one. Anyone
have any ideas?
The SA4000 that I have a techincal manual for (and which is used in the
PERQ 1) uses a stepper motor to move the heads. It doesn't (AFAIK)
require any feedback signal from the platters to go ready...
Let me look at the manual. I can at least see what causes the ready line
to be asserted, and you can check back from that.
