Schematics reviewed and published!

Posted on by Communications Team

We have known each other for several years now, working together with supporters who have backed us through the long process of creating notebook prototypes. Over the last eight months, we have focused on developing a desktop version largely redesigned to be immediately functional.

As promised, the sources for our desktop board have been reviewed by NXP. They suggested a few changes, which we have implemented. The review process cost us an additional €850, but it was worth it: we have improved our schematics and PCB design just in time for the prototypes.

Great news: NXP confirmed we can publish the schematics with an Open Hardware License! We have already uploaded the PDF version to GitLab.

GitLab Repository Powerboard Tyche Desktop Schematics

However, before publishing the raw source files, we need to convert them from the proprietary OrCAD format to KiCad to ensure everyone can use them. We need collaborators to help us bridge this gap.

If you would like to reserve a production desktop board this summer, we need donations to cover €6,100 for the remaining costs of the PCB design, as well as the expenses associated with prototypes and testing in the coming months. ACube Systems will handle the production because we are a nonprofit organization not allowed to sell physical products.

We are doing what is needed to reach production, despite the obstacles. The difficult part, the uncertainty, is behind us. Now we are missing a very simple ingredient: funds. We need to raise a few thousand euros in a window of 2-3 months. Simple, but not easy.

Join us on this journey!

Donate, tell your friends, and share our project. In order to enjoy the PowerPC motherboard later, we must all work together now by joining the donation campaign in large numbers.

Desktop Electrical Schematics Ready! in August.25

Posted on by Communications Team

We are very happy to inform you that the Schematics Design of our new Powerboard Tyche Desktop is running fast thanks to the new Designer and to the NXP Devkit source design plus our Powerboard Tyche Notebook design. Designer took from the NXP Devkit design ( 2023 version) everything is related to the boot process and many parts from our Notebook design, except what is not needed for the Desktop version, like the Battery part.

You can check all the details regarding what we took from Devkit design and what we took from our Powerboard Tyche Notebook design.

At the end of July, we will provide the schematic design and the BOM to the factory, which will then begin the PCB design based on the schematics. Therefore, by the beginning of August (before the factory’s holiday closure), we will know the cost for the PCB design and prototype production. New donation campaigns will then start for PCB design and prototype production.

Today, July 14th, 2025, we’ve officially launched the donation campaign for the schematics. Before the end of July, we’ll make the down payment for the schematics design. We already have funds collected from the previous donation campaign for the CE certification (of the Powerboard Tyche Notebook), so we can advance money from that fund. However, it’s crucial to boost this new campaign and encourage everyone to donate so we can use fresh funds specifically for the schematics design.

Yes, it’s possible to reach the goal to have a working Powerboard Tyche Desktop before the end of 2025, but is needed an extraordinary effort from donors because we depend on donations to cover all the steps that are coming : Schematics Design, PCB Design, Prototype Production and Tests.

Starting from today (July 14th 2025) you can make your donation, thanks!

Milestones

Phase 1: Actual Campaign Schematics Design : goal 30.07.2025

Phase 2: PCB Design : goal 30.09.2025 [depending on donations collected]

Phase 3: Prototypes Production: goal  30.10.2025 [depending on donations collected]

Phase 4: Prototypes Tests. : goal  30.11.2025 [depending on donations collected]

The milestone phases depend from your donation. Thanks!

We remain absolutely committed to making an Open-Hardware Notebook-based PowerPC machine a reality.

As we have already published on our past post we have changed the tactic, focusing on a desktop board first allows us to concentrate on getting the core computing platform stable and functional, tackling the complexities of a laptop form factor (like power management, screen integration, etc.) in a later stage if needed. This is a pragmatic step to ensure we achieve a tangible outcome by our 2025 target. What’s more the Powerboard Tyche Desktop version will be more cheaper than the Notebook version!

We value the experience of making our Open Hardware Powerboard Tyche based on PowerPC from scratch; this is possible thanks to the support of all donors and supporters, and the time and creativity of the activists who have been involved in this project over the years.

We ask you to share every-ware this call for support a strong flow of donations to cross the finish line of all donation campaigns to arrive by 2025 with produced, tested and functioning prototypes!

Progress on PCB Design and on Software

Posted on by Communications Team

Updates on Schematics are being transposed to the PCB design

In February the designer analyzed the Pericom PI7C9X2G608GP PCIe Packet Switch with the direct support of Pericom staff. Now, the Pericom PCIe Packet Switch is fully tested and all the needed setup is completed, so the designer has completed the inclusion of  all required information in the updated version of the schematics and is starting to unravel the PCB. 

The designer has updated the SerDes connections following our suggestions taking into account the notes we have provided, so a new version of the schematics is expected soon.

Arctic-Fox 27.10.1 PPC64 in our Repo

The main contributor to Arctic-Fox – Riccardo Mottola – member of our Power Progress Community association – has released the new version 27.10.1+b0 that we have compiled and packaged in our Debian PPC64 repo. Riccardo says: “Session Store, code greatly improved compared to past releases, performance improvements in both the html engine as well as a new build system imported from Firefox. This release is definitely a great improvement compared to 27.9.19 right at start”

Arctic-Fox 27.10.1 PPC64 running on our T2080-RDB, that has the same processor as our future notebook.

Repository moved to our Power Progress Community GitLab group.

We have created a Gitlab group called Power Progress Community and we moved all our gitlab repositories under https://gitlab.com/power-progress-community. What is important to know is that all URLs have changed and any cloned repository must be rebased. If you have cloned our repositories you should update git remote origin.

Working on Unreal Engine for PowerPC64 Big Endian

We are working on a port of UnrealEngine (UE) to PowerPC 64 Big Endian. We started by forking the PowerPC64 Little Endian (PPC64le) version and we are currently trying to compile the sources. The original PPC64le port for UE 4.23 was developed by Elvis Dowson and Raptor Engineering and can be found at https://github.com/edowson/UnrealEngine/tree/4.23-ppc64le. Access to the UE4 sources requires accepting the Epic Games EULA as described in https://www.unrealengine.com/en-US/ue4-on-github.

We have  modified the original scripts to compile for PPC64 Big Endian but so far, we still have to solve multiple errors leading before being able to generate a working binary. You can find our fork and ppc64 branch here https://github.com/robyinno/UnrealEngine/tree/4.23-ppc64 ( to access it you need to accept Epic Games EULA). We are building the source using both a Power9 virtual machine provided by Open OSU and OpenPower Foundation, as well as on our NXP T2080-RDB development kit using Debian PPC64 SID unstable. If you want to help us on fixing the compilation errors, you can start from our UnrealEnginePPC64 Wiki, please contact us.

C-Media supports our Open Source PowerPC design

Posted on by Communications Team

We announce the cooperation with C-Media. C-Media is a global leading audio IC/software solution provider.

In this post we want to explain one of our latest achievements. During the present year we have been looking for an audio chip to be included in our motherboard. We found that the CM8828 HD-Audio controller and CM9882A Codec family was a good candidate.  After some discussion with them explaining our project, they decided to support us. Furthermore, they have sent the Evaluation Board to Acube.

Maybe more important is the fact that C-Media will provide the needed chips for the production of our notebook. They know that their chips will be in our Open Source Hardware motherboard and will provide us with the needed information to write drivers as may be needed. In addition to this, we have ordered three pci sound cards based on CM8828/CM9882A to test with our T2080 Devkits and for Acube developments.

In the end, all these little steps are very interesting for our project, as this audio chip has high end specs but the most important point is that we have a direct and  good communication with the manufacturer. We want to thank C-Media for supporting our project and believe in Open Source Hardware.

Open Hardware Schematic Published in Alpha version

Posted on by Communications Team

Above all, one of the greatest problems preventing us from finalizing these schematics was the missing chassis required to take a series of very important design decisions. Finally, very recently, a chassis was selected and is now in our hands, paving the way to accomplish the goal.

In April we asked your opinion on either publishing an unfinished work or wait for better quality schematics. The Core Team chose to wait and “Send the information (the work in progress pdf of the schematic design) only to the 132 donors and kindly asking them to not publish”.

At the end of June there was an important meeting between Acube and the designer to discuss the suggestions from our Hardware team, and another topic was how to adapt the schematic to the new chassis. In fact we have prepared the next steps for the PCB design.

So now we have this modified block diagram that could have further few minor changes.

PowerPC Notebook Block Diagram – June 2019

Currently, the designer is working to update the schematics. This task is expected to be completed on August.

In the meantime, the Core Team we voted again in June and this time we have decided to publish the pdf of the current version of the schematic. That does not contain the updates we are expecting in August.

In other words, the schematic that we have uploaded to our repository is the same pre-release version that we have sent to the donors at the end of March 2019, and it should be noted that it is an alpha version. The only difference from the donors’ version is that it contains the recently selected Open Hardware license that is the Cern Open Hardware License v 1.2 (Cern OHL).

We have selected Cern OHL because it is specific for open hardware and it covers aspects regarding hardware production. It has the same viral effects that other open source licenses have but taking into account that there is a licensor of the hardware and another part that is manufacturing it.

The current version of the schematic is published in our repo in gitlab.
