A600 PiggyBackNot V3

This A600 Amiga board has a design error that grounds the LED2 output of the Pi zero on Pin 22

To fit the audio board to this version, solder to the back of the Pi zero and then cut off pin 22 on the other side of the pi zero so that it doesn't make contact with the board when plugged in. Do not remove the pin entirely as the stub on the rear side is required to make contact with the audio board.

NOTE: The A600 will output mono if no cable is inserted in the external audio output so plug two RCA plugs into the audio outputs to force stereo.

LinuxJedi A2000 (Fletch Edition)

The audio is available on pins 3,4 of CN203 and the Audio Ground is located on pins 34 and 36 of CN207.
Some wires are routed through vias and are NOT connected to the vias electrically. When soldering wires to the gold plated fingers, try sticking some Kapton tape to the fingers leaving a just small area at the top exposed which can help to prevent the solder from wicking along the entire finger.

Solarmon CDTV

Note there may be an issue with audio levels which could require resistors to reduce the levels from the CDTV
This is currently under investigation.
