12887 yet, so I don't know how much truth there is to this. I do know
that some of those 386s/20 systems with DS1287s seem to randomly get
their clocks scrambled, and it isn't due to software.
Hmm... I'm thinking
"Stuffed battery" and "Design fault". In that order.
But then again, Dallas Semiconductor do have a reputation for some pretty
strange design mistakes...
MEK = Methyl Ethyl Ketone (C4H8O)? Is it actually
obtainable for most
folks? I thought it was regulated since it is so toxic and dangerous?
Personally, I think I'd take safety precautions while working with the
stuff...
I've heard of it being used to nuke potting compound. Should work on
an RTC,
but it'll probably rip up the screenprint on the caphat at the same time. I
don't have any MEK, nor do I want any - a bit of hacking (in the literal
sense) with a craft knife/Dremel should get the caphat off.
Later.
