yeah, you are right about larry 5, i forgot that wasn’t a talkie, but i still think sq4cd needs the manual. but it sounds to me like you already know which ones need them and which don’t.
by the way, you can find ALL of the manuals you need scanned into pdf files on the internet if you look hard enough.
replacementdocs is a good place to start if they are up, they go offline quite a bit. there is a link somewhere here for the quest for glory ones, and spacequest.net has ALL of the sq manuals im pretty sure.
good luck.
