[NTLK] Delurking and intro

My experience with Newton rechargeable batteries is to use NiMH cells in battery packs that I have rebuilt myself...Frank (Gruendel) has an excellent how-to guide on this. If you've had any soldering experience (some basic electronic knowledge is also a bit of a help), and are relatively precise in your work, you should have no problems. It's actually quite satisfying to open up an old NiMH cell pack and rebuild it. His site is found at http://www.pda-soft.de/hardware.html . Just click on the link appropriate for your machine.
I was very fortunate to have (somehow) lucked upon a still-usable original MP2100 NiMH rechargeable battery pack...which, even after many rechargings in the past year still is holding up (and it's at least 14 years old!)...so there might be others out there. Also, many users charge their NiMH cells (Eveready and Ray-O-Vac, for example) in a wall unit, and then use the becoming-even-more-rare-daily AA battery tray to get them into the Newton.
Hope that's even a small measure of help.

> Great advice, thanks. The eMate is running with its original adapter. The 120 hasn't arrived yet but it should have its own power supply as well. I hadn't even considered the ramifications of a third party power supply, but I'll keep it in mind.

> I'd caught a note somewhere about NiCd batteries being preferable to NiMH when they're being charged by the Newton - something to do with the way the original chargers worked - do you know if NiMH is usable just for power, though, using another charger to top them off?
>> PS I share your weakness for HP calculators, what lovely things they were. What they are shipping now (other than the 12c) is not really in the same county.
> Mmh. I Got one of the commemorative 15c calcs HP sells in a limited edition. Not the same at all. Picked up a nice 45s a little while ago, though, made within a couple months of when they first went on the market. There's nothing quite like that classic feel, or the build quality, or of course the RPN. If HP could bring that commitment to their TouchPad line, the iPad would have some serious competition.
