Hardware developed to implement the computer control of a single-beam monochromator operating under a time-sharing system is described. A stepping motor and associated circuitry yield very precise wavelength positioning in an open loop configuration and with a minimum of computer use. The circuits used to position and step the wavelength are described in detail.
