Supposedly, the 1287 has issues with y2k and beyond, which were fixed in

of those 386s/20 systems with DS1287s seem to randomly get their clocks
scrambled, and it isn't due to software.
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...

Nope... I'm using my Compaq SLT/286 to host
my ancient ISA-based
device programmer. For those not following my ongoing issues blow by
blow, I just got it all working last night. Now all I need is that
replacement DS12887 to show up and I can button the whole shebang up,
nice and tidy.
Feh. Just take a Dremel to the casing of the old one, pray you don't hit
the Li battery and then replace the battery and put some PVC tape over
it. Simple, yet effective. I've seen a website about doing exactly this.
Or you could just dunk it in MEK to dissolve the potting compound
Dalsemi used, then remove the plastic cover and replace the battery.
Again, replace the cover and tape it down. IIRC, Dalsemi used a CR2032
battery in the 1287.
