You can download several different manuals for 1.3 OS, Workbench, etc. by going to:
http://amiga-manuals.npage.de/index.htmlMany of these are in pdf format.
I agree with matt_H somewhat, I just prefer Disk Master II which can be found on aminet.
If you would rather a real paper manual, they show up on eBay for pretty cheap from time to time.
I still use an A1000 with 1.3.3 (and 1.2 for those really old games!) and love it.
Good luck!
