The download links are all still good. Should I grab them all while I can and throw them into an ISO? 

For example : http://download.info.apple.com/Apple_Support_Area/Apple_Software_Updates/English-North_American/Macintosh/Modem/Apple_Modem_Updater.smi.bin still works. 

I can run through the page and make a notepad file with every link and just run wget on all of it
