I'm running on Netscape 2.0 and find I crash alot. Would like to upgrade to Netscape 3.0. I'm on a Mac IICi, system 7.1 with 20 megs ram. I will be upgrading ram to 32 and system 7.5.3. Will this be OK? Where can I get Netscape 3.0 for Mac and is Netscape 4.0 for PowerPC only? Suggestions appreciated.
