Testpoint info
All the Atari demodulator boards that I have, are different from each other (except board 5 and 7) when it comes to the testpoints. All testpoints except TP 1 (resistor), TP 5-10 (pure testpoints) and TP 11 (resistor) works as testpoints av well as jumper connections, as I understand it.
TP1 and TP 11 may have different type of resistors from one board to another.
I decided to include this page, which shows the status of all of the testpoints (except type of resistors for TP 1 and TP 11) for all the demodulator boards I have for sale or trade.
Keep in mind that board 1, 2 and 7 have a few damage/missing components, that needs to be replaced before the board can be used.
The testpoints can easely be changed to the settings for your game.
