Mohnkern) Newsgroups: comp.sys.mac.misc Subject: Mysterious beeps Message-ID: Date: 29 May 91 14:08:28 GMT Organization: Carnegie Mellon, Pittsburgh, PA Lines: 28 I've recently started using a Mac IIci (8 meg, 40 meg HD) for some multimedia production. At random times it "eeps" at me (the system beep). It's not just a simple annoyance. When it happens during a MacroMind Director playback, in front of a large audience, the animation sounds are interrupted for the rest of the animation. So when playing a Director file, I keep my fingers crossed, hoping the beep doesn't come up. The Mac had a lot of odd inits and cdevs installed. I have removed all but the ones I'm familiar with and have used for years. So I suspect it's not an init problem. And since I have 8 megs of memory and am using Unifinder, I don't guess it's a memory problem. Some of the SIMMS must have come from other machines (probably Nexts or Suns), and don't have parity. (Right? They have only 8 chips on the simm instead of 9.) On bootup, I get a dialog box saying the parity circuitry is not functioning. Would non-parity simms cause random beeps? Are there any other possible causes? I'll try to get my hands on some normal simms (to get rid of that stupid dialog at startup). Anything I can do besides that and keeping my fingers crossed? Thanks to all who have any ideas. ken ken mohnkern # the graphics deli # the robotics institute # pittsburgh pa
