I got the iso on Macintosh repository, I think it was universal install. I tried to burn a lot of cd’s with the slowest speed possible, but it doesn’t boot. At one point the Macintosh logo appeared but just after it spit out the cd. Do you now where I can find a specific iso file for my Performa 6360 ?Where did you get the Mac OS 8.1 ISO used to burn the CD media? You’ll need install media specific to your Performa or a Universal install.
I’ll try to burn onto a cd os 7.5.1, but which cd format should I use ? For the moment i use hfs with the disk utility, but i can also use Burn.A lot of these old systems are very fussy about what CDs they will work with and what they won't. I can't get my Beige G3 to read and boot from a MacOS 9 CD I burned on my G4 PowerBook, but it will read one on a different brand of CD burned by someone else. So, first thing to try is burning the install CD onto a different brand of blank, at the slowest possible speed.
Also, these systems were supplied with MacOS 7.5.1, and in the first instance, I'd be inclined to start with that, or perhaps 7.6.x (https://macintoshgarden.org/apps/macintosh-mac-os-76 has universal installers) since is less complex and may be more readable.
The 6360 restore CD is available from the Garden (you might need to use Firefox: at least on my computer the download links don't show up in Safari).Do you now where I can find a specific iso file for my Performa 6360 ?
