See a photo documentary here: <ftp://ftp.linux-mips.org/pub/linux/mips/people/macro/ds1287/> for my proposal of a DS1287 rework. I actually had a nasty surprise trying to rework a DS1287A, with a date code indicating a clearly faked marking. After removing the integrated coin cell the marking on the embedded IC revealed showed it wasn't even a DS1287A originally as the IC was a DS12B885. This is a part I haven't heard of existing, so I enquired Maxim, but they had no clue about it. I suspect the DS12B885 was the core of the DS12B887 (wired differently from both DS12887 and DS12887A), and the DS12B885 has never been marketed as a part on its own. Maciej
