Hello, list members.... I have three PIC questions for the wiser: 1. What is the cheapest POTTING compound I can use to secure my PIC? I have thought of using polyester resin (fiberglass resin), as I can get a gallon at the auto-parts store for cheap. 2. What type of oscillator works best in the Industrial temperature range? I am using a 4mHz crystal. Who supplies wide temp. range oscillators? 3. Last but not least, what is the next step up from my single PIC programmer? Are there faster, possibly 'gang' programmers available? Should I stick to programming them one at a time, averaging 4 minutes each? Thank you, 6500 7000 Dave Celsnak ___7500 / / 8000 (Shift!) /-/ / / RPM / / / /
