Newton Power Supplies

[Rick Dangerous]

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]

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.

 

[Rick Dangerous]

Okay thanks so much! 

I figured there must be some cheap alternative with all the multi-voltage options out there these days.  Appreciate it. 

 

[cheesestraws]

Yup, it's a reasonable voltage, though mildly unusual, with a standard barrel jack type affair where it plugs into the Newton.

Any word on what the required Volts and Mha are for each model? 

Best place to find universal power adapter?

Sorry, only just got off work and then dinner happened.  I'll look for you now.

7v, 0.5A DC, centre-positive connector.

I'm in the UK so no idea where a good place to get one over there is, but I'd have thought any reasonable analogue-ly adjustable one should be able to deal with putting 7V out.

Thanks! Much appreciated.

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?

Mine does.

 

[micheledipaola]

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.

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.

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.
