To make a long story short, I found some _very_ interesting looking stuff in the 'incoming' directory. Apparently tar will happily tar that up for you as well, even though you can't get into it and browse the files with ftp. Namely, files with names like 'RSX89A2.LZ.gz', 'rsx83b1.lz.gz', and 'rsx90a.lz.gz'. Are these DECUS RSX tapes in some weird '.LZ' format? Or disk images? I'm very much hoping they're disk images I'd be able to use with Bob Supnik's PDP emulator (since I, sadly, lack PDP hardware at home right now). Obviously, I know how to un-gzip them, but I have no idea what the '.LZ' extension is. It's not in the comp.compression FAQ either, that I could find. Anyone know what they are?
