DS1386-32K-120+ in Indy

Unread postby diegel » Tue May 03, 2016 1:53 pm

As mentioned in other postings it should be possible to replace the DS1386-8K-150 chip in Indy or Challenge S with the newer DS1386-32K-120. This works if you connect the two additional address pins (3, 28) to GND (16). I have successfully done this modification and it's working perfectly. It's not very clear from the picture: I bent the pins 3 and 28 to the inside and connected it to 16, which is of course not bent. You need to do this modification, otherwise your Indy will not be able to set the TOD clock and will not boot.
