yeah i can help you only if you can afford to loose your iopener. i had 13 to spare so i wasn't worried. actually turbo3 did my mode,
i came close but couldn't remove the r302 resistor. now you dont have to you would just have to solder a resistor on top of that one. still it is hard. i haven't done the audio mode.
sorry, i wouldn't feel right if your iopener fried itself. but you're welcome to get together for a few drinks or capucino and check out our iopeners at the local starbucks anytime.
just let me know what's up.
turbo3 is up in san jose.
