Newton Power Supplies
Posted by: Rick Dangerous on 2020-07-23 23:11:16 Hello All; i have a chance to get a free Newton from a friend (finally, have wanted one forever!) He says "have the model 100, 120, even a 2000. You'll need to get a power supply for it." [SIZE=14.56px]Is any of these models easier to find a power supply for, either OEM or realistically third party/generic?[/SIZE] [SIZE=14.56px]Thanks; and much appreciated if anyone has a source or links to the right supply that will fit any of these models. [/SIZE] [SIZE=14.56px]Was going for the 2000 because it probably has the most software/features/capabilities. Thank you![/SIZE]
Posted by: cheesestraws on 2020-07-23 23:16:43 If nobody's found it for you later, I'll find mine and send you the specs. It's slightly but not overly odd; I have a multi-voltage power supply that will do the job cheerfully.
Posted by: Rick Dangerous on 2020-07-24 00:39:32 Okay thanks so much! I figured there must be some cheap alternative with all the multi-voltage options out there these days. Appreciate it.
Posted by: cheesestraws on 2020-07-24 00:45:19 Yup, it's a reasonable voltage, though mildly unusual, with a standard barrel jack type affair where it plugs into the Newton.
Posted by: Rick Dangerous on 2020-07-24 02:52:25 Any word on what the required Volts and Mha are for each model? Best place to find universal power adapter?
Posted by: cheesestraws on 2020-07-24 03:12:20 Sorry, only just got off work and then dinner happened. I'll look for you now.

Posted by: Rick Dangerous on 2020-07-27 04:26:57 Thanks! Much appreciated.

View attachment 35848 Hi I have exactly the same adapter and it works fine on both a MP120 and 130. I wonder if it could work as well on a MP2000?
Posted by: cheesestraws on 2020-12-30 07:46:27 I wonder if it could work as well on a MP2000? Mine does.
Posted by: micheledipaola on 2020-12-31 04:28:17 Mine does. Thanks! Great news, good to know. I will try to have a battery caddy 3d-printed anyway, or to rebuild the original battery pack, as soon as I get the mp2000 shipped.
Posted by: glay78 on 2021-02-02 00:08:42 Isn’t it 9w? I have it for sale, as well as the dongle, keyboard, battery pack (doesn’t hold charge anymore) and stylus for sale.
Posted by: cheesestraws on 2021-02-02 00:13:02 I don't know what MessagePad mine, posted upthread, initially came with. It isn't at all unlikely there were multiple Newton power adapters for different machines with different sized batteries. Mine is only 3.5W (7V 0.5A) but I wouldn't be surprised if larger-batteried messagepads came with the bigger one you just posted an image of. Mine will, however, power an MP2100, though I don't remember how long it took to charge the battery back when the battery wasn't a paperweight.
