Try www.replacementdocs.com. They have all sorts of manuals and codewheels.

I am just affirming the rules against abandonware. If it is freeware go on and use it. But this Dosbox site has a rule against abandonware and most of the games of IA. are abandonware. I've been on the forums here for almost 10 yrs.

Sorry to burst someone's bubble but the programs on this site should be considered abandonware and should not have support from Dosbox forums as per the rules.
