About this item
Does your vintage PC forget the time and BIOS settings every time it powers up? This new replacement for the Dallas DS1287 real time clock is listed at $20.50. The title also names DS1285, DS12885 and DS12887 as related parts.
Can a failing DS1287 RTC cause CMOS errors on old PCs?
On older machines, a worn-out RTC chip often causes lost date, time and setup settings. Confirm which chip is on your board before ordering.
- Part match: read the marking on your existing chip and compare it with the parts listed in the title.
- Fitting: check whether your board uses a socket or a soldered chip. A soldered chip has to be desoldered.
- Pin layout: look in the seller photos and description for pinout and orientation details.
- Suits: retro computing hobbyists and people who repair arcade or industrial boards.
