That's gonna be a while coming - we're now entering a stage where we won't even understand the code that gets written.
Now, sure, some holdouts will understand the code, but that's not going to be the norm soon.

I totally see what you mean - with minified js bundles and mobile walled gardens we've probably already been in that stage for a good ten years - and AI-driven development that we don't even monitor is likely going to make that worse in the short term...
But I do wonder if LLM-driven code analysis might actually increase code comprehension and agency for laymen?
I've been quite impressed with AI's ability to decipher and visualise code and system relationships in e.g. mermaid diagrams.
Perhaps the representation of code will become more elastic (i.e. you have literal code, or AI-produced translations you can directly manipulate)

Even on Amazon the ESP32 is less than $5 - means like $1 in Shanghai. Various sensors (even the ones with Bluetooth connectivity) are similarly dirt cheap. You can have a bin of such components like you would have a bin of bolts and nuts 30+ years. Basically we live in a golden era of development (which can disappear in US due to tariffs)
>If we think what can come beyond screens and imagine more ambient computing systems - maybe we’ll see new and interesting innovations
my bet is that it will be more robotics related with practically no humans involved. It is a bit of paradoxical - like for example if we add enough development to existing robots we can for example have an AMZN warehouse run fully without people which in turn would mean that we can have robots there much simpler in various aspects as the absence of humans relaxes a bunch of requirements.
Saigonautica · 11h ago
An ESP32 module suitable for hobby use is about 4$ here in Viet Nam. You can get the "raw" ones for maybe 0.50$ less. We're near China, so electronic component price is usually higher than Chinese prices by 1-20% (modules and hobby components on the higher end). If you're ever curious about prices, the good online retailer here is thegioiic ('World of ICs', we love naming businesses 'world of something' here).
Locally, 4$ is probably "more money" to us than 5$ is to you.
Don't get me wrong, it's still a marvel that we can have something so good so cheaply -- but correcting for cost of living, it feels less affordable for us here in Asia.
Anyway, not a criticism. Just sharing a slice of life from over here in case you were curious.

This looks really interesting. I'd love to make something like this myself, from scratch, but I know I'd only get about 2 days into it before ADHD brain decided to do something else. Plus I'd be the only person who'd ever use it, and at that point it would be easier just to use a commercial PC. It could make a cool "cyberdeck" though. I'm already thinking about how I could do the bus stuff for the expansion cards, without having looked at the exact implementation details for this computer haha
334f905d22bc19 · 1h ago
Another ADHD person here and I think my vision is almost the same as the creators. My goal is to build a fully self-hosted risc-v computer from scratch.
It now took me 3 iterations and 3 years to get a somehow working risc-v CPU written in VHDL, that I am mostly satisfied with. It's a crazy hard struggle (finally pipelined though!). Everything breaks, I constantly get headaches and almost want to quit, but somehow I can keep on pushing this project. It helps me a lot.
Almost nothing works, things break all the time, it doesn't even look cool. But somehow it's satisfying that I can type words with a PS/2 keyboard on a VGA screen getting processed by my own RISC-V CPU (running Rust btw lol. I ditched that by now though, the struggle was too big). See here: https://i.imgur.com/PtKeAYt.mp4
I have no idea how far I can make it, maybe not fully self-hosted, but a small OS should be doable. I have interrupts and timers working, so I should have everything I need.
The downside is, I am way worse than OP and have no documentation at all. I should do that, but that's where the motivation is missing.
Edit: I type so slow in the video because I did poll the scancodes (too slow) and had to think which characters not to press, because i dont accept all yet and was scared that it breaks

I'm also having ADHD but you can get help with the focus problem ;)
It's incredible to work for many years on the same thing and it's so pleasing to have steady progress.
So: Go, start building a vision for your cyberdeck! Having a clear goal helps you working towards building it, and you cam embrace the ADHD by jumping around between the many aspects of such a project.
Haha, I've been trying to get help with the focus problem for a while now :P It's gone on my infinite todo list of projects, and maybe I'll get around to it one day, but its true that it would exercise lots of different brain parts.
The most interesting part to me right now is running Zig on a microcontroller, since that's something I really wanted to do this year (like a new year's resolution thing). I've been interested in Zig for a while, but I've never done any serious learning/programming with it, so I might look at your OS repo to at least gain some inspiration on how deploying to a microcontroller works.
It also seems like it would be a really good way to learn embedded electronics in general, since if I wanted to learn something new, eg lower level network programming, I could make and program a network card, or usb hosting, or anything like that.
I'll definitely try to do it one day, once I've finished all my current projects haha

Considering this uses a RP2350, I am pretty sure that no single person on earth has a full understanding of this Computer.
aa-jv · 2h ago
The RP2350 is one hell of a tool, and I've seen it being used to solve some extremely thorny problems with great success.
So I'm pretty sure there are plenty of folks who understand whats going on, especially if they approach their study of the Ashet from the perspective of the RP2350.
Basically, its one hell of a swiss army knife for building computer systems.
echoangle · 2h ago
I can solve thorny problems using Linux on a Laptop too, that doesn't mean I understand even 1% of the system. Even a relatively simple modern Microcontroller is so extremely complex that I don't think a single person could describe every aspect of it in detail.
aa-jv · 1h ago
By way of anecdotal counterpoint, I've got a teenage trainee apprentice working in my lab who can indeed read the RP2350 datasheet and describe what its doing and how to use it effectively in other applications.
I don't think things are as difficult to understand as you do - but then again, I grew up with 8-bit computers where it really was competitively important to understand how they worked - and I don't think the cyclomatic complexity of the Ashet is much greater than anything from that era.
echoangle · 43m ago
Reading and applying the datasheet doesn't mean understanding the whole system. I don't even think a single employee of Raspberry Pi Foundation entirely understands the chip. It's a combination of IP cores and work of many different people, and probably too complex for a single person.

What's the scope of "fully understandable?" How much of this home PC could be reasonably audited by individuals or small teams?
I've got no exceptional opsec needs as an individual, but I spend some time wondering the minimum required resources to audit a PC. Looking through the docs I see cases where there are multiple suppliers for a recommended part -- that's very cool!
As a "fake programmer" and web jockey, this looks like the right balance of complexity to learn with.
ilaksh · 16h ago
I don't think it's really a fair claim in an educational context. There are at least two completely modern computers (which I assume means fairly complex) including the Raspberry PI and another one he is using the the bus or something.
I just don't think modern CPUs really quite fit the claim of "fully understandable by a single person". I mean maybe technically but that is misleading in an educational context where there are much simpler computers that are definitely fully understandable.
Maybe all of the stuff he wraps around the main CPU is understandable though. And the expansion cards are cool.

Ben Eater’s 6502 series (and whole channel) is the gold standard (imo) for understanding how a computer works in every detail.
Some day, whenever I have the money to skunkworks this properly, I've wanted to create something like a modern spiritual successor to the Atari ST with enhanced creature comforts.
Something with a CPU based on POWER architecture (like microwatt) with a simplified multicore design (no hyperthreading or weird BIG+little core design - just straightforward homogeneous cores), a simple expansion interface of some kind, and an OS baked into ROM. Then I'd consider it to be built around a long term support model, with one design that can last decades, complete with schematics, chip design reference guide, and an open specification so it can be easily cloned as desired.
Especially now that Moore's Law and Dennard Scaling has slowed down considerably, it could be a fun platform to target for education or the demoscene, instead of spec chasing.
JKCalhoun · 18h ago
I like that it is using a backplane architecture.
The OS made me wonder how far someone could get trying to create a GUI for the 6502. I suppose the Apple II (GS?) headed there before the Mac fully took the reins and the Apple II was left out to pasture.
BirAdam · 2m ago
Yeah, the backplane immediately gives me S100 vibes.
One comment on the IIgs vs the C64; the IIgs had a 16-bit CPU and tons of RAM, so GS/OS is not necessarily representative of what is possible on a 6502.
I realize that 8MB of RAM seems absurdly small to modern audiences, but I can assure you that I ran early versions of Turbo Pascal and compiled fine with 64K.
ikskuh · 8h ago
Creator here!
I know, i know! This is what makes me a bit sad. I dont know of any modern compiler i can use on the platform, as most hobby compilers target aarch64 or 32/64 bit x86.
What i need tho is a compiler that targets Arm/Thumb-2.
My research tells me that this confines me to:
- A non-complete patch series for TCC (maybe)
- LLVM
- GCC
As twonof them obviously won't run on 8 MB, my options are stripped down to:
- Evaluate CBE and write my own backend and add 32 bit support
- Write my own compiler + backend
Both options don't sound viable before the release as they would increase the scope greatly.

Considered the effort required to add Lua support to the platform? At least eLua would fit and probably provide a great environment for onboard development (i.e. non-crosscompiling...)

The Apple II had a really cool disk drive because of how it did what it did with so little hardware. By relying on the single CPU for everything it was elegant, advanced, interesting... but perhaps not so easy to program.
The Parallax P8X32A Propeller (2006) did multi-core processing in a very beginner friendly way.
It can be done - if you take a holistic approach to hardware + runtime + development environment.
The Propeller probably failed because of the custom language, the custom assembly syntax, the custom ISA, the custom IDE font (!) etc. It was a very neat system though.
spott · 11m ago
The propeller 2 is going to be used as the south bridge for the Ashet.

The Propeller was a commercial failure because it was a one-off part, from a small company, with very little software ecosystem surrounding it, a poor performance to price ratio, and no migration path if you needed more capabilities than it could provide.

Meh. Similar pricing and availability compared to its primary competitor at the time: Arduino.

"Arduino" is a brand of development boards. The direct equivalent would be the Atmel* ATmega168, and that was widely available through distributors, less expensive, had extensive manufacturer and community support, and was part of a broad product line.
What makes microcontrollers commercially successful is... commercial use. Hobbyist applications are fun, but they don't pay the bills.

raphlinus · 14h ago
Along similar lines but physically much smaller, there are currently about 3 or 4 boards[1] that have RP2350, DVI, USB host, and SD card, ranging in cost from about $15 to $40.
A particular sweet spot is emulating 8 and 16 bit systems, as latency can be just as good as an FPGA setup. The infoNES emulator has been running on RP2040 for a while, and I see projects for Sega Master System, Genesis, Apple II, and Mac in the works. But you can also write much more powerful software natively.
Likely it will be possible to adapt software between these various RP2350 systems.

Not ragging on the author, but I'm always confused whenever I see a "make your own computer" project like this that doesn't start with hardware first. I mean, there's already seems to be a quite advanced OS for it and some detailed docs, but no physical "computer" to speak of, just a lot of mockups.
Why a hardware project at that point and not a virtual machine like pico-8?
I'm just saying, its kinda the opposite approach a hardware person would take.

Please take a look at the gallery, where there are photos of the actual electronics setups!
Also don't the mechanical mockups count as hardware? A pile of jumperwires, breadboards and devices don't make a good hero image, but physical hardware mockups do.
Also the electronics design in its current form is actually iteration 5 of the system, while the OS development started with iteration 2.
The OS does boot on the electrical prototype

I strongly disagree! Hardware people love seeing that sort of thing - the more guts you show, the better. It means you've gotten something to work and probably know what you're talking about.

In one way it’s a bit like the Amiga vs the 8088/8086 PC.
What makes microcontrollers commercially successful is... commercial use. Hobbyist applications are fun, but they don't pay the bills.
*: Microchip hadn't bought them yet
A particular sweet spot is emulating 8 and 16 bit systems, as latency can be just as good as an FPGA setup. The infoNES emulator has been running on RP2040 for a while, and I see projects for Sega Master System, Genesis, Apple II, and Mac in the works. But you can also write much more powerful software natively.
Likely it will be possible to adapt software between these various RP2350 systems.

That sounds exactly what i had in mind, and i really wanna do the same when my boy is old enough for computers.
It's a teaching tool and a fun toy to tinker with
I'm somehow very confident in this while also being sure that people probably thought very similar things about home radios destroying the youth in the 1920s :D
>Raspberry Pi RP2350 Main SoC
Yeah right.
Why a hardware project at that point and not a virtual machine like pico-8?
I'm just saying, its kinda the opposite approach a hardware person would take.
Please take a look at the gallery, where there are photos of the actual electronics setups!
Also don't the mechanical mockups count as hardware? A pile of jumperwires, breadboards and devices don't make a good hero image, but physical hardware mockups do.
Also the electronics design in its current form is actually iteration 5 of the system, while the OS development started with iteration 2.
The OS does boot on the electrical prototype
I strongly disagree! Hardware people love seeing that sort of thing - the more guts you show, the better. It means you've gotten something to work and probably know what you're talking about. Take pride in what you have accomplished so far! Ideas and concepts are a dime a dozen; working hardware is a worthy milestone.
Will add a new "cleaned up" photo that isn't also entangled with kids stuff, and other desk content :D
Sadly, it really looks atrocious and it's currently a 3D build which is hard to photograph.
