Re: Microstar 486 motherboard repair

I have to do this for some really old computers that use a Dallas RTC/CMOS chip that.has cmos battery combined with the RTC chip. There is a tutotial online that shows just the right places to grind into to get to the chips internal battery connections and then just stick a coin battery in a holder on top of the chip. Google it.
Done a few of these.

Thanks for sharing this info!
I do have an old DIGITAL Alpha Server that has one or two of these.
Luckily, however, I found a bunch of NOS Dallas chips like that at my former workplace last year and they were also destined for recycling, like many other old things we had these. So I have a NOS pack of several of these ATM.
