Check it out with your handy Web browser (i.e., Mosaic). It should simplify your access into the archives.
Also, I've put the "lost SIG reports" onto the archive. Neither Charles or I have been able to get in the last bit of work to complete and publish them but they are quite worthy even as they stand. You can get them through the Web or if you only have Ftp capability: anonymous login to ftp.einet.net and cd to iceimt/sigsTR.
