hi, I would like to be able to communicate with real time audio on the internet (in lieu of
long distance telephone calls). I have a macintosh performa 6115cd, with 80mhtz. processer, 28mb ram and approx. 300mb
hard disk space. my computer has a microphone input jack (3.5mm stereo), and i have a microphone.I cannot find "system
av" anywhere on my hard drive. If anyone can let me know whether what i want to do is possible with this computer, and what i need if it is possible, i would be very appreciative. thank you.
