Hello everyone,
My TK-II-STEREO has just arrived in the mail. I popped it and a couple POKEYs in my Atari 130XE and... nothing. The computer freezes at the blue boot screen. It will actually boot with a cartridge inserted (like Defender) but the keyboard doesn't work.
I've also found that if I short the mono pin to ground to disable stereo the computer actually works as normal (just with really hot audio output).
Does anyone know what the problem might be? I also have a U1MB in my machine. I read that I should connect the MO pin on my TK-II stereo to the MO pin of the U1MB, and while the computer will work I don't get stereo audio, the U1MB won't let me toggle it, and the audio output is very hot, exactly the same as when I disable stereo manually.
