How do I unpack it ?? It's been compressed with the Unix tar program and GNU Zip (gzip). You should be able to find DOS versions of these (I use djtar from the djgpp DOS port of the GNU C compiler) in the Simtel archive. Use gzip first, and then djtar -xvf to decompress the files. I've not used it, but untgz094.zip in the Simtelnet archive, directory simtelnet\msdos\arcers should both detar and unzip .tgz files.
