This paper is getting older and older, the basic interest is now on the Internet access rather than on Video-on-demand.
The technical details, however, should be still relevant.

It is not pkzip that makes life easy, but compress. Look for an archive called tar-z.zip at the nearest ftp-site. In this archive you'll find both compress and tar, which are regularly used with real computers.
There is also one other tool, that helps, namely new winzip. Check for www.winzip.com.
The compress manual doesn't say it clear, but the decompression can be performed by using the flag -d. In this case:
compress -d pt_adsl.ps.Z
with the exception that PCs are unable to handle filename.first.second type of file names. This is left as an exercise.
If you have any questions or problems, despite of my trust in PC-machines, I'll try to help you if you still have some problems decompressing the file.
