Hi!

Thanks so much for the informative, friendly answers I got to the
first question I posted to this list!

About my duo's unreliable behavior (intermittent crashes, freezes, trouble
awakening, etc -- even after the usual troubleshooting routines and after
clean system install and everything) I'd written wondering whether magnets
might've caused it (since I'd put it on top of some magnets). . . and

I finally got around to trying this -- put the magnets right on the floppy,
moved them all around on both sides of the floppy.  I put the floppy back
in the computer then. I had my doubts, I must admit, but it worked just
perfectly; nothing on it seemed affected.

Yikes --  Isn't a novice more likely to do harm than good when
attempting something like this?  Well, I do have a copy of the 2300's
service manual that I can refer to, so maybe that's enough.  By the way,
how necessary is a grounding wriststrap?  What _is_ a grounding
wriststrap anyway; what's it made out of?  Is it possible to make one
out of ordinary household materials?
What if one disassembles the computer in the kitchen with a couple of
pots of water boiling away on the stove -- would that make the chance
of static much more unlikely (because the air is damp)?

By the way, I was the one that put in the ram card it has now, after
removing the one it originally had (and I didn't use a grounding
wriststrap).  What sort of damage _can_ happen from static (Would
it ever cause assorted, intermittent problems like the ones I've been
having)?

Karsten wrote describing having experienced similar sorts of probs,
which then stopped after changing the system from 7.6 back to 7.5.3.
As someone else commented, 7.6 was known for being unstable, and it's worth
updating to 7.6.1.
I actually am using 7.6.1 -- but it occurs to me that I might try another
system (7.5.x) as an experiment, for example on a ram disk, to see
whether that affects the incidence of the freezing and refusal to awaken.

Hmmm. . . I generally operate under the assumption that the fewer
extensions, the better (even the apple extensions -- which is all
I have on the duo at the moment).  Unless it's something that the computer
seems to need to boot up, or that some application needs to launch,
or unless it gives some particular functionality that I want, I'd
rather disable it.  I'm curious now what the general experience
is about extensions: Might there really be some that don't appear
strictly necessary (because most of the time the computer works),
but which would make things more stable if they weren't disabled?

Again, thank you for the responses!  One of these days soon I will
delve into the duo and do some poking around -- disconnecting and
reconnecting --and some diagnostic tests, as Greg suggests.

Oh, I can well imagine how joyful this would be!  Well, I will keep
you all posted if I make any progress or interesting discoveries.
