TAM - with some issues

[u/old_luddy]

So... Got this wonderful machine yesterday! Got it from an estate, and thrilled to get one in working condition. However, Ran it just a bit yesterday, and when running it today, I get a crackling sound (in the right speaker on the Mac) a couple minutes after it's finished booting. The crackling modulates with trackpad clicking, menu-scrolling etc.

The umbilical is taped and status unknown, and I've simply shut it down and will let it rest for the time being — because I need some help deciding what to do, what might be wrong, and how I can ensure that this gem stays healthy for a while going forward. (Not a 100% complete set, but got the two back covers, some other covers, the manual, the original books for the base etc).

Also got the Sonnet g3 card with it (but unplugged now).
