SYSTEM 6.0.8 HELP!

how do I turn off extensions in system 6?

Move them out of the System Folder manually. This requires using a second startup disk or moving the floppy to a computer which can access it.

Holding down the shift key during startup should disable the extensions. Press it soon after switching on the computer, and don't release it until you get a bomb or until it's clear that the extensions have been disabled.
Would you like help getting a boot disk? The images are freely available for download on Apple's website, and I can guide you through the process of creating disks from them.

That shift key trick may require the Extensions Manager, which was not available until later versions.

It doesn't; it is a separate function which wasn't added to the OS until System 7.

As Grant and Niel point out, the Shift key doesn't disable extensions until System 7. Your only option is to find (or create) a bootable 800K floppy. You can find bootable System 6 images [here|http://download.info.apple.com/Apple Support_Area/Apple_Software_Updates/English-North_American/Macintosh/System/Olde r_System/System6.0.x>, and you should be able to find 800K floppies online. You may find 800K floppies them labeled as 720K (80K are used in DOS-compatible formatting) or as DS/DD (meaning Double-Sided/Double-Density). The process of copying the images onto the 800K floppies requires a floppy drive that is capable of writing to that kind of floppy; if you have any other old Macs, their floppy drives probably will work. And, as I mentioned above, if you need any assistance in creating the floppies, just ask.

Although it seems like 80K is wasted with DOS formatting, the real reason is a little more complex, and has some additional repercussions.

The Apple 400K and 800K diskette drives, originally made by SONY, use a multi-speed motor. This allows them to spin the disk at a different speed at the outer tracks, and get more sectors on the diskette.

But no other manufacturers adopted that drive design, and therefore no other drives can read Mac 800K diskettes. The third-party USB diskette drives you can buy today can read 1.4 MB Mac or DOS diskettes, and some can also read DOS 720K diskettes, but none that I know of can read Mac 800K diskettes.

It is also important to use the proper type of diskettes, as the oxide is different on 2DD/Double Density/720K/800K and the other HD/High Density/1.4MB diskettes. If you manage to fool the drive into writing onto the wrong type, the data can be unreadable in as little as a few minutes.

That shift key trick may require the Extensions Manager, which was not available until later versions. I think that is why Niel said you may have to move them manually.

Niel-

Thanks for that clarification!

Edit: Never mind.
