Here is the manual.
How to use:
1. I have renamed atc6240.djvu to atc6240.zip (because djvu wont getting excepted here. And otherwise i have to handle a 7.2 Mb file.
2. Download it and rename the extension back to djvu.
3. There are convertors online which will convert djvu to PDF file and then its useable. Otherwise you need a djvu reader.
~ At least it can do black and white~
