Actually, Apple supplies disks that will boot any Mac ever made. Look
around on Apple for something called Network Access Disk (NAD). It is a
system 7.5 boot disk image that contains everything needed to connect to a
network (EtherNet or LocalTalk). You can use this the same way as the 7.0.1
you found.

PS my Quadra 840AV is one of only about 5 Mac68k computers that cannot boot
with System 7.0.
