I don't know what the disks on MacintoshGarden are to be honest. But I know for a certainty that the disk images I have are for a Powerbook, the only question is, which model. I've just looked at the images and it has an "Install me First' disk image and a "Install" disk image. Under the Install me first disk image it has a read me file which talks specifically about installing the system on Powerbooks and the need to ensure the correct enabler is installed. The enabler being shown on the Install disk is 111. When I loaded the installer, it definitely had a 'Install this system for a Powerbook 180 option', as well as for the 145, 160, 170 and 180.
The system to be installed on the disks is 7.1. There's about 7 disks I think, an Install me first, an Install disk, an Install 2 disk, a Macintosh basics, tidbits, fonts and printing. No Disk Tools, which I thought was curious.
If you feel these may be of use, buzz me a pm.
