I have purchased a few of these from Maeslin and they are great! However, I now have a system that uses a DS1497 (basically a DS1495 w/ built in battery). Does anyone know if these would work as a replacement for the DS1497? TIA!
Unfortunately it looks like the logic and adressing on the DS1495/1497 is pretty different from the DS12887. I could make up a similar board using a DS1495 SOIC, 32khz crystal and battery holder but I would have no way to test it.

I have a good number of them, unfortunately for single modules the shipping ends up being more expensive than the module itself. If it's a bigger order I might be able to arrange something.

I have checked all pins - but I suspect that the chips I use (cheap ebay stuff) is not working properly (same batch as the first two though). Most mainboards just refuse to boot them, but I got an old bord to boot one of them - and noticed that the seconds actually counted to 100! (showing a time of 04:03:89 and so on).
Anyone know of a reliable (but cheap) source of chips?
Counting seconds to 100 is definitely new. Might point to a poorly-done fake.
I think I got a batch of them off aliexpress initially. I'll have to dig through old email and get back to you.
