Such a system with 4GB is eminently useful for many applications; I have an old Acer Chromebook I installed Linux on and have it sitting in the corner quietly and coolly emulating a VAX system with performance equivalent to a Vaxstation 4000/60 or so.

Are you doing this with https://opensimh.org/ ?

Consider Asahi Linux limited feature support for the M1, after all these years, this is not going to ever happen. Its not like Apple has every shown any interest in opening their hardware up to 3rd party OS support and nor will they.

Did you mean M1 MacBook Air/Pro or is it now possible to install it on an iPad?

I think they mean that Apple is shipping the M5 now, while Asahi only runs reasonably on the M1 (from 2020!), half-works on the M2, and won't run at all on the M3 and above.

Asahi developers have done amazing reverse engineering and driver development. But for the foreseeable short-term, there's no chance of it being installed on a current M-series iPad; it can't even be installed on a current Apple laptop.

I think the Macbook Neo might change that. It's not even an M-series, so there's a quite a lot of work to get Linux running on it. But because it's so much cheaper than the other laptops, and quite powerful, it makes a good "spare" laptop for people who can afford an M-series. And it probably has many internal functions similar to the M-series. I think it might get more attention by reverse engineering enthusiasts over the next couple of years.

Also, AI agents can help experts with reverse engineering labour in ways they couldn't a year ago. (I'd love to do this, if anyone out there wants to pay for it :-)

A tablet that can boot from SD card Maybe it could boot NetBSD https://wiki.netbsd.org/ports/evbarm/rockchip/

> Maybe it could boot NetBSD

It would need a port of UEFI to the tablet, NetBSD doesn't use u-boot and FDT for RK356x SOCs.

I'm in the market for a tablet for my kid. Currently using an iPad Pro which cannot be used with Linux, sadly. The iPadOS version on it does not get updates anymore. You might wanna run something like pmOS on it though, with a UI focussed on touchscreen. Not sure which one is best these days.

Potentially worth looking into old Surface Go's; from what I know they run Linux fairly reliably now and can be gotten suprisingly cheaply (the Go 2 with m3-8100Y processor seemingly being the sweet point of often appearing on ebay for crazily low prices relative to the performance boost if has compared to older/weaker models)

Yet to set one up though so can't vouch 100% there.

Here is the tablet that can do this: https://puri.sm/products/librem-11 . It can even run Qubes OS.

if only it supported sim cards

Then Librem 5 smartphone might be a better choice.

That is also my dream, iPads Pro are very expensive but the hardware is so good (that is including the Magic Keyboard). BTW OP, have you ever tried a hybrid Chromebook tablet like Lenovo Duet 3? This is my favorite device for travel exactly because it is so good as a small Linux machine. Crostini fits the "I want to run a Linux VM". You can even use postmarketOS if you want an even more "traditional" Linux experience…

PostmarketOS is amazing on supported arm chromebooks. Unfortunately the newest 'community' level supported devices are all from the early 2020's and are getting a bit long in the tooth, especially when it comes to web browsing. I have a few that I throw in a bag for beach/jungle holidays - they are literal e-waste, something liberating about carrying a laptop that's worth significantly less than a decent family meal.…

Any tips on best models that are abundantly available used on the cheap and work well?

I definitely do this with a few Thinkpad 11e I have laying around from a failed project 4 years ago.

However I’d really like to switch to e-waste as what you describe would be very liberating. An e-waste Linux device with encrypted disk that you just wifi tether to phone and works fine for use old school types. I wonder how cheap they can go? How easy to flash? etc

not really the same - that's sort of the nice thing about ipads and some business laptops is you can add a sim card and use them anywhere. The MNT Pocket Reform has this but the waitlist is months out.

I have claude code hooked up to deepseek, I hooked up my spare cheapo android tablet, installed adb and fastbook with my package manager and asked the AI to jailbreak the tablet. It discovered the tablet was running a unisoc t606, found a CVE from a couple years ago, and unlocked the bootloader for me. I was the meat puppet holding the "volume up" button and plugging in the usb cable a bunch of times. Like most of my…

Nice work! A cheap MCU and some careful soldering and you wouldn't even need to be around to hold the volume button. What sort of token spend did this take?

About 20 million v4-pro tokens I think

So this is using deepseek-v4-pro / flash and using claude code as the harness right? That's really good that it works. I'm pretty impressed with how v4-pro is doing, sadly there's no subscription packages so I'm not using it too much. (Wafer used to offer it but now they don't).

Yes the claude code software with deepseek v4-pro api configured via environment variables - I've found api access is really affordable
