I have quite a few Microsoft Office/Works manuals from the mid 80s & early 90s. They are well-detailed, and useful for those who really want to learn about older productivity software. I also have manuals for Claris-related software, including ClarisWorks 3 & 4, FileMaker Pro, and MacDraw. And then there's DOS-related stuff (i.e., OS/2, Lotus 1-2-3, etc), plus some manuals I have for my Amiga systems (Workbench 1.3, and my newly acquired NewTek Video Toaster manual, which I can provide pics of in a separate thread for those Amiga enthusiasts out there sometime this week).
Many of these manuals were accompanied with the original software packages I've received over the past couple of years. Most are mint, which is an added bonus.
