I do this with all my old computers. I put a label on the bottom with info about any battery and capacitor replacements that have been done.

If you are fastidious about keeping fresh batteries in your Model T and never letting them run down, and/or you're always connected to a wall wart it makes no difference. If you're like me and get busy with other things and go back to the model T you set aside it's a pleasant surprise to go back days or weeks later and see that the RAM file system is still intact. It's one thing I think Kyocera/Tandy got exactly right. The RAM filesystem is a filesystem. It deserves its own independent long term power supply. -- John.

And when you install them, be very careful to put a sticker on the back of the device to remind you to remove them in 10 or so years. They will eat tracks from PCBs if left to leak.

Re: [M100] With apologies; battery question
I will second ordering from arcade shopper, thats what I did for my M100, but someone mentioned once that you can use a common cordless phone battery from dollar store. I have another M100 waiting to try this on but haven’t Installed it yet. Arcade Shopper is the easiest way to go for a direct replacement though.

Re: [M100] With apologies; battery issue
A super cap will work that is not the problem. The issues come down to making one fit, holding it in place, and that it does not back up nearly as long as the original NiCad did. None of these may be deal breakers for someone, I thought it was fun to try. For the average user popping in a NiMh is easier as it is a direct swap and works the same way the NiCad did.

Re: [M100] With apologies; battery issue
I did a video on this a year or so ago. I used a super cap as an experiment but would not recommend it. A modern NiMh batter works great in place of the original NiCad and will back up much longer than the super cap. While you in there have a look at the electrolytic capacitors and make sure they aren't leaking as well. https://youtu.be/IGTdNMx1V1w I carry some backup batteries and Arcadeshopper has then as well. https://www.soigeneris.com/memory-backup-battery-mbat1 Jeff Birt (Hey Birt!) -Original Message- From: M100 On Behalf Of Hiraghm Sent: Sunday, August 9, 2020 4:41 PM To: m100@lists.bitchin100.com Subject: [M100] With apologies; battery issue Naturally after entering lurk mode I would develop an issue with my M100 with which I need advice.
