It works great.. A friend of mine is making me a lucite >enclosure so you will be able to see it and still have it protected. I put mine together last night, about 3 hours. Here's an important hint about something that didn't catch me, but could have: Capacitor C16, 10nF, marked 103, looks exactly (except for a single digit difference in the markings) like capacitors C2-7, C18-23, C27 and C28, 100nF, marked 104. Since there are so many 104's that look alike, that mistake would be easy to make. (I probably had to desolder and exchange those capacitors in over half the parallel universes.) My problem is that it when it's plugged in, it sends out data and so prevents the CPU form working because of interrupts. (A Mac SE/30 runs very slowly (~100x slower), and motion on an SE is imperceptible.) I can digitize with it plugged in, and then unplug it and play back the sound and everything's fine. Since other people don't have this problem, it is something wrong in the one I built. It is my understanding that when the digitizer is not sampling, it is suppowed to be unpowered. Is my understanding wrong? mine always has 5 V available. If that is not how sampling is turned on and off, how is it done? Please mail me instead of posting. If there is general interest (which I doubt) I will post a summary. Thanks for the help. -- David Palmer palmer@gap.cco.caltech.edu ...rutgers!cit-vax!gap.cco.caltech.edu!palmer I have the power to cloud men's minds -- or at least my own.
