today I learned that the Philips CD-i consoles have a clock battery which is permanently formed into the clock chip, meaning you have to *break open the chip enclosure* to replace it 😨 https://cdii.blogspot.com/2009/03/picture-guide-of-cd-i-battery-repair.html?m=1
@ticky yup! Super popular with a lot of computers of the era.
I'm surprised there isn't a drop-in replacement.
@ticky i wonder if it's compatible with any of the others in https://pc-restorer.com/replacing-cmos-batteries-in-old-pcs/
i would guess not, since ST apparently made a bunch.
