Here's a question for a historical expert... I have some floppies made on a Mac in January 1990. A modern G5 will not read them. A M$ Windoze XP machine, after installing MacDrive5, also can't recognized the format. What are the most modern machines that should be able to read them?? (Modern enough to find on campus I hope). The machine that wrote them was color, and likely one of these models (so 800kb or 1.4mb I don't know): Macintosh IIci 1989 Floppy Drive: 1.4 MB SuperDrive Macintosh IIx 1988 Floppy Drive: 1.4 MB SuperDrive Macintosh II 1987 Floppy Drive: 1 or 2 800k 3.25" (upgradable to 1.4 MB SuperDrive) Macintosh Plus 1986 Floppy Drive: 3.5" 800 kb My thanks to the long term Mac expert who can answer this! Chris Added later: The floppies say on them: "MD2DD Double Sided, Double Density, Double Track"
