If somebody has these old Bonus Disks, could be nice if create a torrent of them to share with other people using the old versions 
By other side, you can install software yourself (like the office from the bonus disks or games), for that you can use the commandline package manager "sudo apt-get install ...", or maybe installing synaptic (if is not installed by default)
But, probably the debian repositories are dead (verify that by running "sudo apt-get update"), in such case you can still access to them by using the "archive" debian repositories explained here and here
Feel free to improve this very basic howto with better instructions
