Fellow time-techs,
Nothing lasts forever, and my faithful Odetics 425 is doing its best to
demonstrate that fact. Before I put "Fix or Replace the thing" on my
project list for the new year, I thought I'd check to see if any other
owners of the beasties have run into the symptoms I'm getting.
Specifically: The unit will go from TIME LOCKED and TFOM=4 to TIME
COASTING and TFOM=5, pretty much at random.
What I've done: Reseat every IC the thing has, replaced a couple of
interconnect cable DIP sockets with hi-rel machine-pin style (they were
cheapie single-leaf before), and done a manual recalibration of the
oscillator.
I know for a fact that the single-leaf IC sockets are a huge source of
problems in older gear. My next step would be, I'm thinking, to replace
every single IC socket with a high-rel part (that's a LOT of
desoldering!)
So -- Any thoughts before I start ordering new chip sockets? ;-)
Thanks.
