You can download the .torrent file here :
http://btjunkie.org/torrent/TRS-80-Com-Site-Archive/443254adc82b02b3b8bedb6f4a8ae943f9cb5c6987bb
If you do not yet have a torrent client I recommend uTorrent which can
be found here: http://www.utorrent.com/
Looks like the above link is not working right now. You can also find
the .torrent on the following Yahoo Groups file areas. I know the
torrent from the Yahoo groups works because I can see it seeding to
more than one peer right now.
File is called trs-80 archives.zip
