Dialup Support Information for older MacOS VersionsThere are a surprising number of older Macintoshes out there - especially in schools and small businesses. A 1993 Macintosh is still surprisingly useful - but it won't be able to run any of the newest system software or enjoy any of its simplified networking benefits. So, you should be prepared to at least make an attempt to provide support for users running MacOS version relics like System 7.1 through System 7.5.5.
In 1994, Apple switched the CPU in its new computers from a CISC Motorola M68000-series chip to an Apple/IBM/Motorola PowerPC-based chip. While PowerPC-based Macs (those using the 601, 603e, 604/e, G3 and forthcoming G4 chips) retain backward compatibility with software compiled for the M68k series, the same doesn't hold true in reverse. If a user has a Macintosh whose name includes a "II" or a number with only three digits, it's a "68k Mac," and it won't be able to run any version of system software newer than 8.1.
