I want to point that this is an open source hardware project.

https://gitlab.com/power-progress-community/oshw-powerpc-django

It can be modified, or copied to be used as a base of a new project... Indeed, I'm pretty sure the developer will be happy to have some help.

@deuteros76

To be honest, I've already offered to design a powerpc mainboard for free when I returned to the amiga two months ago. After a reply that my offer was very generous and the question if I was willing to sign a NDA, it went silent.
I would love to play my part in the community. But not without any perspective that it will actually see the day of light including OS4 support.

Taking into consideration that the number of potential buyers is quite limited, I very much in doubt that any potentially interested company would ever guarantee that a project will see the day of light.

Please, have a look at the KiCad material on GitLab that Manuel alone prepared and consider to team up with him. A core team, instead of a one man show, would certainly give a better chance of survival to this project, and hopefully, you'll reach a point of development able to motivate a potential hardware maker.

Even if you have divergent ideas on what the final motherboard could be in terms of shape or type, position and number of ports, you may work together on common issues, and then work separately on your separate branch.

Welcome to wonderful world of Amiga where promises are plentiful but actually delivering as rare as hens teeth. Also worth of remembering that your average Amiga business nowdays makes middle school bake sales look highly professional.

I don't know which organization are you referring but Power Progress Community is not requesting to sign any NDA. The association is focused on producing open source hardware and you can find in its Gitlab schematics of the notebook project and also for this new low cost board design.

If you want to collaborate in a PowerPC hardware project you can contact the association and check if you like what you see there.

I hadn't seen that, and cannot find that now. I'm curious what you had in mind, and if you are still interested and willing in that. It seems you have opinions how to do better than the Django idea, and if offering for free, it would be great if you were already doing so for yourself. :)

@deuteros76 @billt

Disclosing the company will only do damage.

I offered free engineering. Not free prototyping. When I spend these two~three months for the schematic and layout I end up with files. From there to actual hardware running aos4 still takes substancial investment.

Considering my commercial hourly rate and a full blown development including a second prototype cycle, vhdl for a cpld, verification&validation, documentation, certification support and manufacturing support we are talking about 160-200k euro for just my effort. And if I have to, I will also port uboot.
On a board that would sell 1000 units, this saves 160-200 euro excluding VAT to the end customer.

I do not know what it will cost to port Amigaos4, but this would already be a step into the right direction when it comes to "affordable" amiga hardware.

If you have a serious plan with financial coverage that will have a large change of ending up as real hardware with aos4 than my offer still stands.
Personally I would like to make a T2080 board. But if demand is higher for a lower cost T1042/22 board than this is ok for me as well.

I am finalizing another Aos4 project at the moment. The ones who have been watching os4depot closely can take an educated guess

So you will have until the end of this month to prepare a plan

If you like to make hardware for Amiga market this are things you should consider.

Part of problem, I think is number people wonting to design hardware for Amiga, they lacked the skills or the money or the time, its key to success here will be keep It a small project, they keep costs down.

TTM Time To Marked, the time to design test and make sure its working, is key components have self-life. If TTM takes too long the components you use will not be obtainable. Or hard to obtain at decent price.

Reuse, driver already exists for number sound cards, and network card, and sata controllers, getting the product out into the marked quickly will depend on reuse, if new hardware is picked it can delay TTM. Only if all hardware is EOL, should new hardware be considered, or will be EOL.

Quantity, cost of producing only a few compared to producing millions is pretty big, there for make little to no sense replicate what is already on the marked in quantitys, so good design should be minimalistic, it should provide ways to plugin products from the self.

FPGAs should be considered, due to the unpredictable nature of the self-components, FPGA key benefits, can be fixed, after its on the marked by flash upgraded, will most likely not go out of date, often FPGA takes up less space on motherboard, because they can include, sound, usb, sata, and network in one package. Temperature and voltage sensors, fan speed regulation. Can also include things like blitter, ciaa/ciab, and other legacy chips no longer in production for better backwards compatibility.

If its likely that part can need to be replaced, it should be design in way to make it replaceable / upgradeable, so that avoid complete redesign, modular design.

Design should also make as easily as possible replace firmware without bricking the computer, to make it as safe as possible to update and write firmware.

Should avoid any incompatible PowerPC isas to avoid having to spend years trying to workaround things in software. (I say go for full featured CPU AltiVec, 64bit, 32bit, dual or quad core, DDR3, standard FPU).

Just to clear things out, are you aware that the PowerProgressCommunity (PPC) is made of a bunch of volunteers (many amigans) that focused their spare time around the PowerPC notebook project to give it a chance of success?

I am very much in doubt we could come up soon with a solid "financial coverage", and in any case, I think the plan could only consists of multiple donations campaign as we are doing for the notebook. Moreover our little resources (=our spare time) are currently concentrated on the notebook prototyping and now on the Django project.

The Django board is a recent idea we had for providing developers the cheapest ever possible PowerPC that could run a 64bit environment with a decent enough CPU that has not strange quirks (see the FPU of the NXP P1022). Preserving the shrinking PowerPC software developers community is out #1 priority at the moment. We were lucky enough to find an engineer that is kind enough to use his spare time to develop already quite a lot, it would be nice of you to help him out to address issues he is having.

Alternatively, if you are willing to contribute you spare time for developing a T2080 based hardware that could potentially run AmigaOS, why don't you join the PPC community effort of the PowerPC notebook?
We are in such a need of an electronic engineer able to deliver a good enough motherboard.
By any chance, did you ever looked at the schematics available at https://gitlab.com/power-progress-community/oshw-powerpc-notebook/powerpc-laptop-mobo ? What do you think about that?
