I'm looking for a hardware guru who can advise on using an old G3 iMac for its modem to connect a Macbook to a dial up ISP. The G3 is running OS9 - while the Macbook is OSX (10.4 of course) - any ideas? Can this be done? Or is it off to the apple store to buy a modem..... Any help is greatly appreciated! I'm on the road and won't be able to check in as often as I like, but will send good will and kind thoughts to anyone who can help!!
