Link is not working for me...
I would be very interested in getting a new battery for my Cosmo.

Hello to all Planet owners,

I was planning to register, but today's finding , made me register to share this with you.

What do you make of this? Is this finally worthy equivalent for our spares?

Cameronsino cs-plx600sl battery for planet Gemini tablet (sxx600) 4150mAh

To, if possible, preserve context, I'm trying here first. So, in the hope that someone still reads this old stuff: Greetings!

First, since someone seemingly still pays to keep their web sites up, their support email still issues tickets (that nobody replies to) and their shop, though stale, still offers things, is Planet Computers meaningfully active? Do they take orders? Do they ship? Has anyone heard from them? Are there any vital signs? Early last year Dom (shymega) was working on negotiating employment with them. Did anything ever come out of that?

Second, as some may recall, about two years ago, I sent my Astro to Planet, as a deficient update had disabled its screen. After giving them every benefit of doubt, the present reality is that instead of returning it, fixed or not, they ghosted me and essentially stole my Astro.

Last, as I recently relieved my still working Cosmo of its last important duty, I am contemplating to backup the thing, factory reset it and try to donate it to someone interested, preferably in Sweden, together with my remaining Planet paraphernalia, including an old Gemini, an unused car mount kit, an unworn Planet T-shirt and some other accessories. While I haven't quite made up my mind yet, would there be any takers of the lot here?

Yes, I know there is another part of the forum for that purpose. For now I'm mostly trying to gauge interest, if any.

Zaurus - pdaXrom / Re: Sharp Zaurus linux in 2025

Sadly, I dont do embedded linux development any longer. It's been MANY years since I've owned a Zaurus or done any Linux development. If I had time I would certainly get back to it, but unfortunately I don't. I also do not have access to the pdaXrom site. That is still owned by sashz and I've not spoken to him in years.

Sorry :-(

Hey InSearchOf, glad to see you back! I hope everything is well with you. PdaXRom is IMHO still the best Zaurus ROM in terms of hardware support and has the best GUI for our old little devices, although projects such as VoidZ are more than welcome to bring recent Linux developments to the Zaurus.

What about you? Do you still have any Zaurus, and/or develop anything for it? BTW, it would be really great to have the download links and install guides for pdaXrom back on the pdaxrom.org site, for future reference.

Zaurus - Void Linux support / Re: Void Install Guide
« Last post by Varti on August 28, 2025, 12:09:22 pm »
Hi Varti,

Great to hear about Void's new release news—super excited! Any word on the release date?

I’m already using Void Linux build-8, plus the new kernel Greguu released in Jan 2025. Void feels really lightweight, but I’ve run into some challenges too.

Also, do people still use Arch Linux? Any tips to share, like on GUI or productivity? Eager for Void-related insights too!

By the way, I have a question: the USB hosts of C1K and C3K cannot provide sufficient power to support external devices. How can I get these devices to work properly? Thanks.
No release date yet unfortunately, I hope greguu can update us on the current status of the release.
As already mentioned by DiTBho, an externally powered USB hub/device is unfortunately required.

Do you mean external hard drive?

that's how I compile kernels for all the platforms I support, mainly MIPS, POWERPC and HPPA2.
I wrote a "builder" in bash-scripting + C/89, to help managing patches, configuration, and checks

Every build comes with a "profile", which tells about
  • the toolchain, with constraints on the min and max versions of binutils and gcc
  • the ecosystem (it's called "qualified machines", can also be a chroot, or a container), to ensure you are using the right setup, at least "tested"
  • the final size of the kernel
  • the final file-format { uboot, elf, bin, zImage, ... }
  • etc...

Here, it checks a file in ensures that the .config contains options considered "essential", and that it does not contain options considered "to be avoided"
