Abstract:

An inexpensive interface which uses Zilog Z-80 microprocessor compatible interface chops and allows instrumental control and data acquisition using a Radio Shack TRS-80 Model 4 microcomputer is described. This interface provides parallel and serial data handling capabilities useful to a wide variety of instrumentation. A block diagram of the TRS-80 compatible interface is presented and the TTL signals which are used for chip selection, control and inputoutput functions are discussed. Examples of the application of this interface to a commercial Photochemical Research Associates fluorescence lifetime instrument and an in-house, multidimensional fluorescence detected circular dishroism spectrometer are provided.
