001- My display is sharp but it seems to be unstable. Is
there a quick, easy fix for this?
Maybe. First, check your cable connections to make sure they are solid.
Also, try diddling the side and back controls. Sometimes, these become dirty or
develop bad spots.
If diddling a control seems to cure or nearly cure an unstable, jumping,
etc. display, you can be fairly sure that a squirt of Control Cleaner will help.
The cleaner needs to reach the control's resistance element-- the place where
the wiper touches the carbon track in a potentiometer-- and you should turn the
control back and forth after squirting the cleaner. Probably, you will need to
remove the case to get a good shot at the dirty control.

002- My Apple IIc has the IIc RF modulator module and is
connected to a color TV through a TV/Game switch. The
color is okay but the display is more or less ragged
depending on where I run the cable. Is there a way to get
a better, more stable display?
If you are using a plain hi-fi type cable to connect from your IIc
modulator to the TV/Game switch, then, changing to a video cable may help. If
you are using a much longer cable than necessary, try a shorter cable.
Another popular trick is to form any unused length into one or more loops
(use wire ties or tape to hold the loops together). Wrapping unused cable
length around a ferrite or iron core (e.g. from an old transformer) is a
variation on the same idea.
