I know that both Links (aka: MacWWW) and the older Lynx are text Based Browsers that can work on System 6, as there are ports for them on the Apple II+/e/c/gs. You will need System 6 TCP/IP to work with them.
Things get tricky with graphical browsers, most want System 7 with TCP/IP. But Mosaic can be tricked to run on System 6. Thing is, it requires at leas 4MB of RAM, so it will only for on a Mac II Series or a SE/30 with 8MB or more. The same with Netscape 2.0.
MacWeb seems to be better as it can work on B/W Macs but wants System 7, damn. One could tweak it to work on System 6 with TCP/IP. It can do either Text Only or Text & Graphical Browsing. You'll need Resedit to do the tweaking with.
