1) The eMac won't be able to handle it, the PowerBook G3s -- I wouldn't know about that, but they do have internal floppy drive "inserts" (Including the PowerBook Weight Saving Device :approve: ) which should work. The 280c definitely couldn't either, since looking at the specs reveals no FDD (unless external). You might end up doing a 1.44MB -> 800KB operation -- suggest you figure out how to get that thing connected to a network.

Link which also can be traced back to
here. (If you look down you'll see disk images for 800K disks) I have a bunch of open windows stuffed with tabs as I'm working on my SE/30 and software, I can offload some links for things you might need if you want.
EDIT: A tremendous asset to you at this time (Does your hard disk work?) is a RAM disk. If you don't have 4MBs of RAM, you should do everything you can to do so. (I can offload some unused 1MB modules to you if you want).
I definitely love RAMDisk+ 2.01 under 6.0.8. Start the application, hold down the option key or click the mouse, specify the size of the RAMdisk (leave enough for what you need to do!) and press Enter. It'll copy your startup disk folder into RAM, and boot into it. If you wiped your HDD and just installed a fresh install of 6.0.8 (using the RAMDisk as your startup drive), once the Installer quits you can switch to your HDD by heading into the System Folder and CMD-Option double-clicking the Finder file (as long both are the same versions). You'll switch boot drives in a flash.
