Slimbook to provide the notebook chassis

One of the main points when you are designing a laptop is the relationship between the motherboard and the enclosure. It is not a good idea to design the motherboard if you don’t have the chassis. At the same time, the enclosure has to take into account how the motherboard will be.

Now we are happy to announce that Slimbook will provide the enclosure we need for our Open Hardware PowerPC notebook. ACube and Slimbook are collaborating since the beginning of this year, exchanging information about components disposition and pinouts, thermal dissipation and so on. 

ACube is a well known company with experience in creating PowerPC computers including  Sam460ex and Sam460cr motherboards or the AmigaOne 500 desktop system.

Slimbook is having a great success selling their own Linux laptops (such as the ProX) and mini PCs world-wide.

Due to this collaboration we have almost everything we need to achieve our goal in terms of technology. 

Electrical Schematics final version

We want to update you that first days of October we will publish in our repository the pdf containing the final version of the schematics. After that, during October,  the Orca source will be available as well, tailored for the Slimbook chassis. This means that the design of the PCB will fit inside the Slimbook chassis.

In case you are able to convert Orca source to Kicad you are welcome to do it. If you have any issue when doing so, contact us and we will be happy to provide some help.

New ppc64 applications in our repo

Lastly, we have patched the following applications for ppc64 (Big Endian) : arcticfox, palemoon, mame, fs-uae, libx265, qemu, midori.  They run on PowerMac/ImacG5 ( Power4 processor) but also on more recent Big Endian ppc64 processors such as NXP T2xxx and T4xxx.

We are also working on many other complex applications like Blender that require the creation of dedicated groups for the distribution of the necessary effort.

We’re performing tests, reporting bugs and suggesting workarounds to complete the installation of Debian 10.0 using ISOs released by the maintainers of Debian ports for ppc64be.

If you want to join the software workgroup and help these software tasks feel free to contact us.

We finally found a viable solution for the notebook chassis

Acube Systems, the company carrying out the electrical schematics design, is also investigating a possible motherboard layout that would fit into an existing notebook chassis. However, this research is delaying the publication of the electrical schematics, the goal of the first donation campaign. This –initially unplanned– activity is a necessary step that is required to properly launch the second donation campaign, the one aimed at the PCB design that should take into account a target notebook chassis. The main problem facing the second campaign is going to be the high temperature generated by the MXM video card, that, together with the CPU and other onboard chips, will require a properly designed thermal dissipation mechanism in order to obtain a stable system. Once the few remaining aspects will be cleared up, most probably by the end of October 2018, we will be ready to publish the electrical schematics, and after that, we will be ready to launch the second donation campaign.

PowerPC Eletrical Schematics

To get into details, and as already described in the past, finding a notebook chassis was an unexpectedly difficult task, and it was mostly due to a lack of a manufacturer or a notebook reseller willing to provide an unbranded and empty chassis. The good news is that after 3 years of tireless research, ACube Systems finally reached an agreement with a company allowing us to buy and use a notebook chassis without restrictions. The bad news is that under this agreement it was not possible to obtain an empty chassis, forcing ACube to buy a complete laptop, then take the x86 motherboard away (and possibly, reselling it).

 

The first release of the PowerPC notebook will fit into the above mentioned disassembled notebook chassis. In parallel, our voluntary-based mechanical 3D team is assessing the feasibility of an Open Hardware notebook chassis that would fit the PowerPC motherboard layout. Hopefully, ACube Systems will be able to provide two distinct batch of notebooks, a first one using the off the shelf chassis, and –possibly– a second one, later on, using our custom chassis.

In any case the Open Hardware PCB and the Open Source Notebook Chassis will be useful for other Open Hardware notebook projects. There is a much bigger community out there that will be able to appreciate our effort!
