I stumbled across an very active torrent for 16 GB of old Mac software. I did a few spot checks of some of the items in the download and they seem to be OK (i.e. resource forks intact). So I downloaded the lot for myself. If anyone wants it, the torrent file is
javascript:file_download('/bbs/download.php?bo_table=torrent_util&wr_id=12851&no=0',%20'MacOSSoft.torrent');
You may need to manually insert "javascript:" in your browser
I think there will be a number of items in there that could be uploaded here on MG.
