title: A fast data acquisition system for neurophysiological signals based on a personal microcomputer.
abstract: A general purpose analog-to-digital conversion system and its interface for a low-cost personal computer (Commodore 64) are described. Special emphasis has been put on achieving a high sampling frequency rate (up to 20,000 samples/s) and a high discrimination (12 bits). It has likewise been attempted to increase the number of input channels (up to 8, by means of a multiplexer) and averaging capability since such features may be useful in a great number of neurobiological studies. Commercially available hardware elements have been employed and software has been developed in BASIC and 6510 Machine Code.
