Are there any slabtop’s still being made? All of those that you listed are discontinued.

I do like the idea of having a very small, limited OS. I’ve often thought I’d love an updated Psion 5. With modern batteries and displays, you should be able to get months out of a set of batteries or battery charge.

The READY Model 100 is the most recent commercial one to my knowledge, that was crowdfunded initially and then sold via their online store, but is currently unavailable to buy further units of.

There's other things like the Freewrite if you just want a word processor, but I'd recommend the much cheaper (albeit discontinued) AlphaSmart Neo 2 over that, especially for the battery life.

Everything else these days is largely hobbyist DIY projects who occasionally make a PCB or chassis/case available.

I'd love for the segment to grow again. It's admittedly niche, so that's quite unlikely.

Loved and love Psion!

Clockwork makes several

R-01 is particular interesting for having a RISC-V processor

I was so sold on the Clockwork stuff until I realized how small it is. They're more of a handheld thumb board!

If they scaled it up, I'd love one, especially a RISC-V SKU.

I ordered the CM4 Lite uConsole kit almost immediately after opening that first link.

That's a great price for a 4GB RAM CM4 given what they currently sell for on Amazon/eBay.

I currently own an A06 DevTerm but have been unsatisfied with it. Clockwork OS feels lacking, I wish there was a stand for it, and the keyboard isn't great. The uConsole CM4 can theoretically run Raspbian, has a built-in stand, and features a more compact keyboard. Better overall IMO.

If I end up liking it then I will go for the RISC-V option. Of the available RISC-V options I know of, it appears to be one of the best.

Thanks for linking the review.

That machine sounds great except the battery life. 6 hours? Why can’t it be 600 or even 6000 hours? The Model 100 came out 40 years ago and could go 20 hours on smaller batteries!

I suspect that display is one of the biggest bottlenecks if attempting to build a more power-optimized device.

There are still some low-power cyberdecks around, like https://hackaday.io/project/184340-potatop

Do you know of any with normal sized keys?

[wlesieutre]

I don't

There was a demo of a Linux OS that simply boots to vim and that’s the only thing you could do on that machine. It would be perfect for this use case.

[criddell]

Linux is pretty heavy compared to something like EPOC that the Psion used. That machine would run 20 hours on a pair of AA batteries.

We’ve come a long way since then. Surely a month on a pair of AA batteries should be possible?

[xwdv]

But we have lithium now.

[criddell]

Sure. As long as they are a standard battery that will still be around 25 years from now.

In the year 2050 you can probably take your Psion 5 from 1998, insert AA batteries, and start writing.
