Atari 800 computer Adjustments

[Sean39]

Hi every on

 

I know on te back on the Atari 800 computer has the GTIA Graphics adjustment. Now when you open a Atari 800 computer and look

at the bottom of the computer there is a small hole going to an inductor coil. I think the coil is L101 but what is this coil used for ??? What is this

adjustment used for. It may be an oscillator type circuit if so what frequency should it be at???????????? Well anyways it is the only opening

on the bottom of the Atari 800 computer.
