A system which was developed to automate a programmable experimental stimulus paradigm and to record the resulting eight analogue signals and to enable subsequent signal processing is described. The recorded signals consisted of an EEG, some EOGs, an ECG and the PGR (psychogavanic sway) of a subject who was required to respond by pressing a button. The signals were to be cross correlated so simultaneous sampling was necessary. Both continuous and discontinuous recordings were required. Erroneous responses were to be discarded and the reaction time to button press was to be measured. A/D overload was to be avoided and the A/D converter sensitivity was to be maximised. The system was required to communicate with a mainframe computer. It was to be compatible with an EEG machine. The resultant design had to have general application with some software and hardware modification as necessary
