N2 - A simple microcomputer interface, consisting of only three integrated chips, for the input of digitized data from a uv-vis spectrophotometer is described. The interface multiplexes four binary-coded decimal digits, four possible decimal point positions, and an algebraic sign into a single eight-bit parallel input port of the microcomputer. The interface design is also adaptable in a general fashion to any analytical instrument which can present digitized data, with the expansion capability of accommodating more than the number of digits and decimal positions noted in this specific example. Software developed specifically to drive the interface and several general applications to computer-assisted kinetic studies are discussed.
