I just bought an old Powerbook 530c to use to transfer files across to the MacPlus, works great. The powerbook has an ethernet adapter which I've connected to my local network but the installed system (7.6.1) doesn't seem to have any networking components installed. The powerbook didn't come with the system disks, so I can't use those.

I can get a copy of system 7.6.1 but what's the best way to get the networking components installed on the powerbook?

It only has a floppy drive no cd.
