If you use BitTorrent or any type of NZB downloader, you can oftentimes find the Snap-On GM Electronic Parts catalog available for download.

Just search for "GM EPC" on some of your favorite torrent/nzb sites. The set contains two ISOs that you can mount/burn and install on any computer running XP.

The EPC gives you exploded diagrams and information on a lot of GM vehicles. It's come in handy a few times when trying to figure out how something should come apart.
