It's now wellestablished that computers don't merely relieve the tedium of much experimentation and enable it to be completed more quickly and more precisely than when performed manually, they permit a whole range of new experiments to be undertaken which would be quite impossible without a computer. The purpose of this paper is to describe a corrosion electrochemical measuring and analysing system based upon an apple IIe personal computer and a TP801 single board computer. The system can perform many electrochemical experiments, real-time display and print experiment data in both text and graphics. Analog to digital, digital to analog and logic control circuits were designed. One GPIB interface which has the whole ability of listening and taiking was designed with software, and using asseble language, signals genarating, data acquisition, time and manager etc. software package was designed, using excellent applesoft, one manager software package in apple IIe was designed. Under the control of the software package one can input parameters, select experiment technique, save and display experiment data etc. with manmachine talking. The system has been tested in off-line and on-line, and proved to be reliable.
