I always get turned around with spacial relationships in the written
word.....
Comparing the linkage position to the one on my working unit. It is indeed
in the "deactivated" position and does NOT move when a key is pressed [as a
clarication, the "far" ent of the linkage extends through a slot on the
front of the keyboard assembly. On the working unit, qhen no key is pressed,
the end is down, it travels up when the key is pressed and returns down
when the typing unit finishes its cycle. On the new unit this end is always
in the down position].
Attempting to move the linkage (but not overly forcing it] is futile.
Visual inspection of the path [at least what I can see without moving the
typing unit out of the chassis bay], does not reveal anything. Are there any
typical binding points? Should I be thinking about a seized clutch?
