Then the cmos battery is probably in a Dallas DS1287 or similar chip. There are hacks to replace the battery itself with a CR2032 holder, but it requires drilling into the chip.
I bought a DS12887+ to replace it, and socketed it in case it would need replacement again in the future (in another 30 years? :)). But if you want to go this route look up what chip is compatible with the exact one you have.
No, the reason it doesn't work is that IDE to USB adapters don't support pre-LBA HDDs. These old disks are all CHS-addressed.
I wanted to take images of such disks. I ended up managing to boot an ancient version of Knoppix from a CD (just booting it was a nightmare) and then using dd_rescue to clone it to a file on a CF card connected vi a CF-to-IDE adapter.
Edit: oh, drive powers off when usb is connected? Might be that the adapter doesn't offer enough power, but if you could get around this you would inevitably run into the problem I describe above.
For example, maybe branching is something you'd like to be able to do without it being a nightmare?
Right, afghans aren't arabs

It looks like something out of an early 2000's game
Services are automatically restarted. There is no automatic reboot by default, but that can be enabled if you really want to. Otherwise it'll keep track of whether a reboot is necessary or not.
I've been running Debian stable with unattended-upgrades on servers for years and have had no issues whatsoever.
As somehow living in that region of Sweden, that was my first thought!

That joke has aged like milk
It will say "Dallas DS1287 REAL TIME" and be unusually thick for being a DIP chip.
I just remembered, there's a third possibility for replacement if this is the problem - the nwx287, a hobbyist-made replacement chip that has a cr2032 holder.
