Writing a Floppy Disk from an Image Classic Mac OS I hope to make them available soon using Disk Copy 4.2 format for maximum cross-platform convenience. I’m currently cooking up some Mac boot floppies that will make installing System software a breeze. These will be immediately useful without any decompression. If StuffIt Expander isn’t available, attempt to find the necessary disk image in uncompressed Disk Copy 4.2 format. This free program is available for Mac, Windows, and Linux/i386. Before these disk images can be written onto real floppy disks, they must be decompressed with StuffIt Expander. Many sources of Mac floppy disk images distribute them in StuffIt (.sit) format. (All other vintage Macs have a 1.4 MB SuperDrive or FDHD floppy drive, which is compatible with modern computers.) StuffIt Expander This means that boot disks for a Mac 128K, 512K, 512Ke, Plus, pre-FDHD SE, or un-upgraded Mac II cannot be made on a Mac OS X, Linux, or Windows machine. When written to a floppy, these images create exact copies of the master disks.ĭue to physical differences between Mac and PC floppy drives, 800K double density Mac floppies can only be written by other vintage Macs. These floppies are distilled into disk images you can download from the Web. Installing System 6 or System 7.0.1 onto an older Mac is only possible using floppy disks, and the first step to installing System 7.5 is usually “boot from a floppy”. And that’s what we’ll talk about: Free tools for writing Mac floppy disks and HFS CD-ROMs using modern Mac, Windows, and Linux computers. To get that vintage Mac up-and-running, you need to be able to write downloaded software onto disks that an older Mac can read. 2007: One of the biggest hassles of the vintage Macintosh hobby is loading software onto your first older Mac.
