I'm at wits end. Spent hours & cannot get LC III to start up. Get smily face and the message "This startup disk will not work on this Macintosh model. Use the latest installer to update this disk for this model. (system 7.1 does not work on this model; you need a newer version that does.)
That's not true as Apple site indicates 7.1 is compatible. No matter what floppy I insert I get that same message. Disk tools etc all result in same message. Have even tried to reload 7.1 from floppies and get the same message. Any expert that can help?? Thanks, Herb

When starting up, try zapping the pRAM by holding down the following keys

Command + Option + P + R

Let it chime about 3 - 4 times, then let go and see if it boots.
What OS was on the machine before you started messing with 7.1?
I would go with OS 7.5.5, which is available at Apple's site

Thanks for your suggestion. I had previously zapped Pram without success. Hve since discovered my problem: Needed the 003 Enabler in the system folder. Works great now.
