Indeed, all modern releases of Fallout 1/2 that I know of contain the manuals in PDF format on the discs. Usually they're in a folder labeled "Extras" or "Manuals".
If I recall correctly... the FO1 manual is about the size of the Fallout 3 manual ~but spiral bound and five times as thick.
Yeah, I think thats about right.... Its either A5 Paper sized, or just a off that size. http://en.wikipedia.org/wiki/A5_paper_size (Close to half a US "Letter" page rotated 90 Degrees).
