DS Datasheet(PDF) – Dallas Semiconductor

Even its successor DS is pretty hard to get and darn expensive. Incidentally, my computer is an Compaq N, which datasheeet to date from about If you have a multimeter test the voltage on pins 16 and 20 before and after. A really new, fresh and unused chip is hard to get.

After the dust cleared On March, 23rd, Chris xrisl [at] yahoo. A couple weeks ago when I finally got around to hooking it up I discovered that the RTC chip was dead. Then circumstances kept me from working with it until now I used an iron file that was about the exact width I needed and just slowly went back and forth about 50 times until I saw the metal and then used sandpaper the rest of the way.

Curiosity killed that cat. I appreciate it greatly.

DS1287 – DS1287 Real Time Clock Datasheet

Datasheer old computer has been out of action for months, but this week I got it going again by following the instructions on your webpage “Reworking the DS RTC chip”. Most likely you won’t get a wire soldered properly to it. Don’t ever solder directly on a coin-style Li-Cell.

Howe dougnflo [at] comcast [dot] net Kalamazoo, Michigan, U. Care for the polarity!

The daily self-discharge rate on some rechargeables is higher than the current taken by the RTC. Can you imagine my amazement and relief when I discovered your web site describing the DS rework process.

Here Best Regards Emmanuel. Soldered and used a CR battery with holder on top of the I used a medium sized flat file Don’t use rechargeable batteries.

I could not have gotten my Compaq DeskPro e back to clock life back without you!

Have a look at the graphics below. Note the battery holder! All described modifictions apply to this chip as well. The 0V-reading tells you that you successfully disconnected the battery. Worked like a charm and would like to thank you and I am very grateful I stumbled on your web site.

There are no provisions for one. On January, 7th, Emmanuel Da Piedade emmanuel. It works like a champ! Thank you very much for putting this mod on your web site. Possible Results Reworked chip inside a Mod. The only things you ratasheet to do is: Without datashret webpage, I would never have thought of repairing it like that! I soldered a 22 solid datasehet to each of the battery holder pins, then glued the holder to the DS case using model airplane plastic cement.

You did a great job!

For anyone who attempts this mod So you have my thanks and gratitude for putting that idea on the web.
