need classic system folder

Hey all. I had to reinstall my osx 10.4 on a ppc a while back and now I no longer have what looks like a classic system folder. I had it when I bought my powerbook on Ebay but I guess I need the "Additional Software & Apple Hardware Test" disk to get it back or something. I only have the first one apparently. Anyone know where I could find this, or a place where I could get the system folder for the classic environment?
