I was watching "How It's Made" on the
Discovery Channel this morning,
and they were constructing speakers. As they went to magnetize the
ferrite ring, I noticed the operator working with an interesting
three-button control panel.
The button he pressed was a red "Fault"
light/button. To their left
was a beautiful white "Ready" light/button, and one marked "Write
Protect". This strikes me as a very interesting magnetizing
apparatus.
These are definitely swindicators (switches/indicators) from a DEC RL01
or RL02 drive. You can see the unit select number has been "obscured"
in some way (white paint?) on the "READY" switch.
Wonder if they are using just the switch assemblies, or perhaps using
the big voicecoil positioner of the RL01/RL02 as part of the system that
magnetizes the ferrite?
