Well a 386 may not count as vintage yet (or ever ...) but isn't it more
in keeping with the spirit of what we do here to hack, twist and bend
the modern to fit in with the old, where possible? Shouldn't the OP pull
a pin on a common or garden cable rather than drill a mobo connector?
I pulled the pin :-)
I got the compaq setup program to work but it would still not boot.
I'm sure the DS1287 rtc has lost it's battery but I would have thought
it would be ok as long as I didn't turn off the power.
I reset all the settings but it complains when I reboot that it does not
have it's settings. %^$^$^%$#$.
Am I high to think that if I buy one of the DS1287's on ebay it might
work? Or all those so old that it's a waste of money? Anyone try
lately?
A while back I brought an IPX back to life replacing the dallas chip,
but that was easily 5 years ago, maybe longer.
(I even tried putting the old compaq ESDI controller in a newer pc, but
it's not happy; it does auto discover the drive & geometry but the boot
fails with an error that looks like a bios problem)
I'm going after the DS1287 with a dremel tonight and solder a 3v battery
to it :-) hi ho!

I've bought DS1287s off eBay that work fine. I always socket the
little bastards when I replace them though. :)

I've considered buying a minimum lot of new ones from Maxim. that'd
set me up for another 20 years or so. I'd have about 992 to sell, too!

Can you still get DS1287s from Maxim? I know you can still get
DS12887s, but they're not always compatible.
What might be best is to find someone's cache of MC146818As and
forget about the internal battery.

I did that with my Compaq 286/SLT, using a low-profile socket, and that
made it too tall to fit under the bottom of the battery bay. Since I
didn't have a battery, I drimelled a hole in the floor of the battery
bay and it fits reasonably well.
For a desktop machine, of course, there's rarely any concern of vertical
clearance.
