The last 68k Macs needed 7.5.1 or 7.5.2 to boot (with the appropriate 
Enabler). 7.5.3 will boot any 68k Mac, all the NuBus PowerMacs and 
quite a few PCI PowerMacs (7.6 dropped support for pre-68030 Macs).

I think Apple provide all the machine-specific Enablers on their FTP 
servers too, which are necessary for certain machines on certain System 
versions.
