There are two Boots branded typewriters in the collection, so why not a Boots calculator as well? The Boots 224 Memory is a nice late 1970s machine with a square root and percentage functions to go along with the basic four arithmetric functions. As the name implies, the calculator has memory too and works fine, numbers displayed using an eight digit VFD display. This is in fact a rebranded Casio Memory B-1.
