Hm. I'd use 7.1 (with Update 3) on a Macintosh Classic, actually. Much nicer system IMHO. You'll also quite probably find more software for it. A Classic makes for a *very* nice typewriter with
- MacWrite (any version)
- Microsoft Word 5.1a
- ClarisWorks (only if you can't find MacWrite, for it takes longer to load).
I'd make sure to get the 7.1 system disks, though, so you can reinstall, should it ever be necessary. System 7.5.3 is much easier to come by, but it requires more performance from the computer (RAM, mainly).
