I just stumbled on this during one of my regular dives into Archive.org

Some great documentation on a wonderfully unique and classic Z80 system. And one that made heavy use of bank switching to stretch out it's memory space.
The Osborne was not only a neat little historical oddity, but the origin of the business term The Osborne Effect, due to the circumstances behind Osborne Company's famously grim fate.
