This is a custom disk image made by combining the System 7.5.3 (revision 1) installer and the Network Access Disk 7.5. This Makes a bootable disk image containing the 7.5.3 installer. You can use this on a Mac with a fully formatted (erased) hard drive, without having to create the separate bootable floppy. Just a single CD that can boot and install.
Boot disk compilation created June 2016. Component system software released 1994 & 1996.
Tested on a PowerMac 7300.
