Color Classic Mystic Upgrade Help

Hi everyone - I recently was fortunate enough to come across an LC575 board (Mystic) for my Color Classic which the original board had become extremely corroded. I was given the Color Classic a few years ago from someone who did not remove the battery and it caused a pretty large mess. I was able to clean out the system and this morning put the LC575 board in.

It appears that the current drive has System 7.1 installed and needs to be updated, as I am getting the following message on startup:

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.)

I have a usb floppy available on a PC. Can I download a startup disk / tools disk or upgrade set?

I also have a Power Mac 7100 running System 7.5 with a CD-Rom drive.

Thanks very much for the support!

You need a system enabler for system 7.1. I would recommend system 7.5.5, because you don’t need one.

You can do a net install so you don’t have to make floppies.  I would make a backup of whatever you need and do a fresh install though.
