Rebuilding a DS1387 RTC/NVRAM Module

1 post in this topic

Posted (edited)

I started repairing an old 486-based industrial system today, which uses a 486 SBC in a passive ISA backplane. Most (but not all!) consumer hardware uses a RTC with a little CMOS RAM and an external battery and crystal, but potted modules are common on industrial/embedded hardware. Unfortunately this one uses a DS1387, for which there is no modern replacement. Several other people have repaired the DS1387 and posted writeups on the process. Here's my rebuild:

I used a CR1225 and holder due to space restrictions, here's the final result:
