Nice, the project is getting more and more attention.

Talos board and blackbird covered too.

The problem is that T2080, price has gone up, it might be that this CPU is no longer being produced in large quantiles, this might be wherey well become really expensive laptop. Already the crowd funding has pretty expensive, anyway can only hope some of experience gained is not lost, maybe design can be reused for different cpu’s as well.

What are the prices for PowerPC's like T2080 ? Can't find anything in stock or a price at this moment.

$400-530 @1.8Ghz depending on SKU.

Thanks!

@Rose

Where did you took those prices from?

I see a different price range on mouser, it seems much lower to me

Digi-Key with on stock prices. Prices are usually quite much cheaper with +5 month lead time.

Where are you looking? I see them for around US$300. And Avnet has them in 44 quantity for less than $250 at 1.8GHz.

No pcie slots. Just two m.2 slots. One for an ssd and one for a wifi card. So no audio. Amigaos will not support USB audio anytime soon. Didn't hear anything about NVMe either. So not really useable imho.

m.2 slots are PCIe slots...

What do you mean no audio? What do you mean no NVMe?

I replied to AmigaBlitter in #163. There he has a link to this new Django T1042 mainboard.

I am aware that M. 2 slots have PCIe. But the keying suggests a modern NVMe ssd and a wifi card. Of course you will find other M.2 boards like 4G modems as well. But you'll probably will not find a soundcard. So you have to work with m.2 to PCIe converters. (if they exist).

If Amiga will support audio output via HDMI, you will be able to hear sound using an M.2 GPU board such as these https://www.innodisk.com/en/products/embedded-peripheral/display

These cards mount a SM768 chip, an evolution of the SM502 mounted on the Sam460ex
https://www.siliconmotion.com/download/3PT/a/SM768_WP_4K_High_Definition_EN_201910.pdf

@virgolamobile

Otherwise great plan but SM768 doesn't have audio.

@virgolamobile

I think we will get USB sound sooner than hdmi sound. But there is also the issue of the gpu. The issue is that there is none. Only a standard display controller to hdmi. So this board could have some use for industrial applications. Unless you make the m.2 to PCIe expander.

OK, there wasn't anything linking to that, in a topic about a laptop, so I didn't have reason to know you were talking about something else.

The T1040/T1042 is capable of i2s (iis) audio connection on TDM port. Perhaps he will make use of that somehow.

Well, if a SM768 cause problems, you may plug a M.2 to PCIe adapter and then use standard GPU board, these adaptors are quite cheap, see for example this one https://www.aliexpress.com/i/32866587414.html

@billt

They use a usb3 cable to transfer PCIe. That is just two high speed pairs. So a waste of three pcie lanes in processor which has only 8 to begin with.

I know we Amigans are used to frankenstein machines but I would rather use a more performing solution.

The same processor could work with a I2S audio codec and a x16 slot in a mini-itx form factor.

But micro-atx with
- x16 slots with 4 lanes
-2 times x1 slot
- 2 sata

would be my preferred solution.

@virgolamobile

if that solution works depends on the location of the m.2 slot.
