Various projects somewhat related to the EOMA initiative
by Paul Boddie 29 Jun '22

29 Jun '22

Hello, There doesn't seem to be much EOMA68 news any more, but I was reminded of some of the ideas brought up in the context of the initiative by a few products or projects that came to my attention recently. One interesting product is the Mixtile Blade 3 which just about met its funding goal on Crowd Supply: https://www.crowdsupply.com/mixtile-limited/mixtile-blade-3 The interesting idea that this implements is the ability to daisy-chain the boards using PCI Express, and there is also a cluster box that provides a switched PCI Express bus. In the context of EOMA68 or similar efforts there was this idea: https://rhombus-tech.net/community_ideas/cluster_server/ The Mixtile Blade 3 uses the Rockchip RK3588, which has also been introduced in products from PINE64: https://www.pine64.org/2022/03/15/march-update-introducing-the-quartzpro64/ Another notable development from PINE64 is an impending introduction of a RISC-V-based product (these having started to emerge from various other places, often based on the Allwinner D1): https://www.pine64.org/2022/06/28/june-update-who-likes-risc-v/ >From the choice of GPU technology, it seems like this might be the basis of the SoC being used: https://www.imaginationtech.com/news/imagination-and-andes-jointly-validate… ImgTec have now started to work on Free Software drivers for various products, as I understand it, although I doubt that older products will be supported, and the firmware will most likely remain non-free. I would love to be proved wrong, though. It's a shame ImgTec didn't have the same level of ambition and pragmatism when they owned MIPS. On that topic, David posted news of an interesting project on the Tinkerphones mailing list: https://lists.goldelico.com/pipermail/community/2022-June/002206.html To summarise, someone has been pursuing the development of a featurephone using the Ingenic X1000E: http://www.ingenic.com.cn/en/?product/id/9.html That SoC has a relatively small amount of on-board RAM (64MB, which counts as small these days), but it could run a very modest Linux distribution. Unlike earlier Ingenic SoCs, but like the JZ4780, it has a hardware floating-point arithmetic unit. And it also has the different on-chip peripherals for easy integration into portable devices. Relevant EOMA-related ideas include the following: https://rhombus-tech.net/community_ideas/games_console/ https://rhombus-tech.net/community_ideas/hybrid_phone/ https://rhombus-tech.net/community_ideas/pocket_qwerty_computer/ https://rhombus-tech.net/community_ideas/zipit_refit/ I haven't spent or pledged any money towards any of these initiatives, but for anyone wondering whether some of the EOMA-related ideas were ever taken up in some sense, I thought they might be of interest.

Green (literally photosynthetic!) technology to team with EOMA-68
by Richard Wilbur 14 May '22

14 May '22

EOMA-68 seems uniquely positioned to benefit from this type of technology! Low-power, long-endurance designs could make some pretty cool applications. “Algae-powered energy cell can keep a microprocessor running around the clock anywhere with sunlight” https://www.zmescience.com/science/algae-powered-energy-cell-can-keep-a-mic…

Door bell cameras can pickup conversations from up to 25ft away.
by David Niklas 03 May '22

03 May '22

Dear luke, The data from these cameras and microphones is stored in the cloud. This means that all the audio and video captured is vulnerable to interception and unauthorized access by other people and the US government. https://www.consumerreports.org/video-doorbells/video-doorbell-cameras-reco… Sincerely, David PS: I did not think they had microphones.

Schematic and PCB layout CAD files
by Arun Isaac 01 Feb '22

01 Feb '22

Hi, Are the schematic and PCB layout CAD files for the EOMA68 computer card and the various housings available for download? I'm wondering if I can fabricate some of the housings on my own using a CNC mill. Hence, my interest in them. Sorry I had to ask. I searched very hard through the crowdsupply page and the rhombus-tech site, but couldn't find them. Thanks, Arun.

SparkFun MicroMod

This looks like another interesting reuse of an existing connector: https://learn.sparkfun.com/tutorials/getting-started-with-micromod Not quite at the System on a Chip level hardware, but still useful for certain applications, I'm sure. David

Hardware description language Clash.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Dear luke, I found this project that is similar to Haskell. IIRC, you said you'd like to use Haskell as it can be formally verified when designing what will hopefully be a silicon FLOSS processor. So, I think this project might interest you. https://clash-lang.org/ I hope you're doing well.

Pluton: M$ firmware and TPM to be built into your processor...
by David Niklas 13 Dec '20

13 Dec '20

Hi, It has been a while since I posted. Today I have bad news. Apparently, M$ has been working with AMD, Intel, and Qualcomm to place a new type of TPM into their CPUs, APUs, and SoCs. It's already inside of the new XBox processors. It runs firmware which is, according to M$, produced by them. Here's an official link, and a tech site link for those of you who don't want to visit M$'s site. https://www.microsoft.com/security/blog/2020/11/17/meet-the-microsoft-pluto… https://www.anandtech.com/show/16269/microsoft-pluton-hardware-security-com… I've done some research googling, but at this stage the data on what sort of access this new processor has and what it can do is anyones best guess. It sounds like the firmware might have unrestricted Internet access: "One of the other major security problems solved by Pluton is keeping the system firmware up to date across the entire PC ecosystem." I hope I'm panicking unnecessarily... David
