We have a pretty recent Mac II with a Radius display and a 40 Mb Jasmine disk drive. Problem: it seems to have pretty bad hardware flakiness. We can't get it repaired though until we either know what it is, or at least it becomes steady-state broken and not just intermittent. Symptoms: in the middle of *anything* (editing, Finder, compiling) a squeal comes ripping out of the speaker. It's so raucous that at first I thought it was the drive head plowing into the media surface, but I'm quite certain it's coming from the speaker. Seems to happen more often the warmer it is in the office. Has anyone seen this problem before? What needs to be replaced? Could it be purely a software problem? (The interrupt switch won't dump us into MacsBug. The screen gets shifted up and to the right, or variations of that.) Any hints at all? Thanks, Daniel M.
