I have a mid-90s ThinkPad with Windows 95 and Office 95 sitting on my shelf. I cannot do anything with it, because the battery is long gone, it has no floppy, no CD-ROM, no network. But every once in a while I turn that thing on. Still runs like a charm, and the performance is good, too, for its age. (It better be - it's one of those butterfly notebooks, those must have been pretty expensive way back when...)
