The (in)famous System 7.5 Network Access Disk is what you need. Get it here:
http://download.info.apple.com/Apple_Support_Area/Apple_Software_Updates/English-North_American/Macintosh/Utilities/Network_Access_Disk_7.5.sea.bin

If you can't get it decompressed let me know and I'll mail you something you can directly dd on t 3.5" floppy.
( this should be a MacBinary II encoded StuffIt archive with an unpacker in the resource fork - any StuffIt expander should be able to handle it )

have fun
Michael
