held within carts computers radios trx and any media
that uses quarts crystals
the quarts comes from other than one mountain in california
so they are not IC grade in atari or other
so drift with time
by more than 100ppm
mostly these units have a lifetime and factors like 1ppm drift
but have a life time
other than replace them there is no choice to just unsolder and turn them around
as the drift is polar
and they become polerised with time
so all the crap in them at atom level moves around
so replace or as a test turn them round
it wont cure a failed machine
however it will effector the state of things like colour and glitch you encounter
missing levels on game carts
etc etc
best replace a resonator like a electrolytic cap
every 10 years ....
i write models for many things in c++ for simulation
and i always build in there time in life factor as a measure of uptime and use
its time people realised a crystals doesnt stay static .. and this affect there whole retro machines
ability to process
a good analogy is flushing a toilet voltage being water and current the fifo effector..
if you flush current you drag atoms in a particle stream...
