The orginal introduction is in file "READ.ME".
I have the book with its 5"1/4 floppy disk, but no hardware to read it. I guess I've found these files on a forum, so I can not garantee that they are what they stand for.
It is at least the 2nd time somebody ask me for these, so I put them online.
If it is a problem due to copyright, malware presence (sorry no scanner at hands) whatever... please open an issue.
