Hi all! Long time no talk.. I haven't forgotten about everything and everyone here though. I've moved to doing most my development on AVRs due to the GCC port availability. I *finally* after multiple years have finished my midibox SID. It took 2 SID chips, 3 recasings, 2 resolderings, but I finally have a unit that for the most part functions.. the SID was my first DIY synth and through making it and remaking it, it provided me the basis to go on an make a number of microcontroller-based AVR projects from scratch as well as build a x0xb0x :). Anyways, my SID does this weirdo thing. Peridically, maybe after 10 minutes use, it will sound "grounded out", and the contrast on the LCD will freak out so it appears that both lines are completely solid on the LCD. If I leave the unit on it will go away after awhile - it used to take a long time like a half hour but recently the glitches are shorter, like 20 seconds. If I turn it off and on it doesn't immediately fix it. Could this be a faulty/tempermental SID chip? I'm looking for someone to say "yup, I had that problem, faulty SID".. if no one does I know how to troubleshoot most everything else but I'd rather not have to start seperating my modules again to hunt for the problematic module. Thanks! Tom
