>for a 68030 computer
However, in this very case, System 7.5.3 should be quite sufficient (even without later updates). A Network Software Selector, allows a choice between classic networking and Open Transport. For a Classic II computer (which, may not be the ideal Internet machine), the "classic" setting with MacTCP (instead of the TCP/IP control panel used under Open Transport) could be a good alternative. For dial-up, a separate PPP program is needed. A (third-party) text-based web browser such as WannaBe should work at a reasonable speed. System 7.1 may be even faster/better for a Classic II, but does not include MacTCP (nor any other Internet software) from the beginning.
