This incident reminds me of the debugging situation I had to do in Botswana some 23 yrs. ago. I had rigged up an air-conditioner that was controlled by a microcontroller, a novelty at that time. The temperature got so hot and the humidity so low that the microprocessor, an 8080, just wouldn't run right. I solved the problem by circulating water over the enclosed unit. Liquid-cooling so to speak! Computing forever; forever computing.
