I was trying to connect a generic microphone to my Beige G3 and it didn't seem to work. So I tried another one and that one didn't seem to work either. I looked it up the Mac OS 9 help guide and it told me to use either a USB microphone or a PlainTalk microphone. Why is this? What's so different about PlainTalk than a regular microphone?? And to solve this problem, I have the video input/output personality card in my G3. In this case, couldn't I use a microphone jack to red/white stereo cable converter and just use the input sound from RCA In?
