Initially a drawing board covered with dirt or sand that might be written on to do mathematical equations. Particular mention of the a counting framework is 17c. or later.
instead called the counting framework, an abacus is a mechanical product regularly assist an individual in performing mathematical computations and counting.

In the preface to the appendix containing the local arithmetic he states that, while devoting all his leisure to the invention of these abbreviations of calculation, and to examining by what methods the toil of calculation might be removed, in addition to the logarithms, rabdologia and promptuary, he had hit upon a certain tabular arithmetic, whereby the more troublesome operations of common arithmetic are performed on an abacus or chess-board, and which may be regarded as an amusement A facsimile of this document is given by Mark Napier in his Memoirs of John Napier (1834), p. 248.
