My college course in electronic instrumentation had a lab section that used an E&L Instruments ADD 8000 for the experiments. I always wanted to get hold of one for my own use. I felt like the one I used was mine, anyway. They came in kit form, and since we were the first class, we had to assemble them. They were quite unaffordable by a poor student at the time, though. Anybody else familiar with this prototyping system or run across one anywhere? jbdigriz
