Welp, I have spent the morning playing with/exploring my Pomona DM250, and I have to say, it's proving a LOT friendlier as a distraction-free writing sidecar for #scrivenerapp than I'd expected! Makes the advertised features of the Freewrite Traveller look weaksauce, and it's only half the price.

Retro writing 15 – Pomera DM250

Art vs. Entropy

At some point I should probably write up a comparison between the DM250 and my first portable writing deck computer, 1989's Cambridge Z88 (from Sir Clive Sinclair). 35 years on, the DM250 is half the weight, 120% greater battery life, 1000x the built-in storage, CPU is about 1000x faster, screen is infinitely better ...

And less than half the price (adjusted for inflation).

@cstross
I liked my Z88
Made on-call visit notes on it, imported them into Idealist, printed them on sticky labels. Easier than my handwriting.

Now there's a TCP/IP stack for it, I saw. Might dig it out one day.

@midgephoto There's even a Mad Bastard (soldering *definitely* required) recipe for ripping out the RS-232 port and replacing it with a bluetooth transciever (serial over BT) for file transfer to more modern hardware!
@cstross ha! I had a Z88 as well. Can’t say I miss it, unlike my work-issued HP200LX a decade later.
@fazalmajid It could have been *so much better* (I still have mine)! The membrane keyboard was surprisingly good. The display … they now make e-ink panels about the same size? I'd love to see a revival of the concept: A4 footprint, with modern hardware like a Raspberry Pi Zero 2W and micro-SDXC reader, and about 5mm thick. Could even run Pipedream under emulation, considerably faster than the original.
@cstross you could jury-rig something using a RaspberryPi 400 combined with an e-ink display like those available on AliExpress:

The question is whether their usually SPI interfaces can be driven or even bit-banged from a RPi.

@fazalmajid This started with a discussion of the Pomera DM250, which it turns out can run Linux mostly happily …
@cstross how does your impaired vision cope with the tiny screen? I tried one of the GPD Pocket subminiature laptops with the 7” display and the Planet Computers reinterpretation of the Psion Series 5, it’s just too small for my tired eyes. The 12” MacBook was nearly ideal in form factor and usability. Nowadays I carry either a 13” M1 MacBook Air or the 15” M3 version when I can.
@fazalmajid Yep, I got that. The DM250 font size can be increased; I find the default is okay, but anything smaller is right out. (It's a full-screen editor and defaults to 16 lines of text, on a 7" display. Which is *just* enough for me. The Freewrite Traveller, with a 5.5" screen, would be on the wrong side of small.
@cstross @fazalmajid I have a 6-inch e-ink panel sourced from an old Kindle, waiting for when I have the energy and space to build *just* that very sort of thing.
At the time, A4 sized panels were pretty hard to come by. It's likely much easier now!
@rajelaran @cstross e-ink is still way too expensive, specially in larger sizes. You'd think their use in programmable shelf labels for supermarkets would create economies of scale and bring prices down.
@fazalmajid @rajelaran I've never seen a programmable shelf-edge e-ink display in a supermarket. Is this an American thing?
@cstross @rajelaran programmable as in they can be written by RFID, they probably don't have enough processing capability to run actual apps or even WiFi, and eInk refresh rates are just too slow to do something like rotating promotions advertising. As someone else pointed out, Aldi has them. They cost about £10 in bulk and some have 2 colors, usually black and red, like this one I bought to tinker with:

@cstross just saw this on Crowd Supply (like Kickstarter for hardware projects, much less sleazy): https://www.crowdsupply.com/zerowriter/zerowriter-ink

@fazalmajid Noted: the screen is tiny and the wrong aspect ratio for the keyboard. (And I don't like the e-ink lag when typing: it's only good for reading.)
@cstross oh, you'd mentioned e-ink in the context of the Z88. I prefer LCDs or OLEDs myself. It would seem like a 8" tablet combined with a Bluetooth keyboard and some distraction-free writing software should do what you need without hunting for niche hardware. Isn't Scrivener available on the iPad? If you're worried about your low saving throw against Shiny, you could always use iOS' Guided Access feature to lock you into that app.

@fazalmajid The LCD on the Z88 was very bleeding edge at the time—eye-bleeding! E-ink would be better than that, but a good OLED would be miles better than either.

Scrivener on iOS is a mixed bag—better than nothing. Scriv has increasing sync issues with cloud services these days. Literature and Latte are beta-testing a new app called "Written" that gets sync right AND has the perfect core feature set—it's like iOS Scrivener 2 done right (but it's not file-level-compatible, so a new app).

@cstross For productivity with these devices do you focus on writing that doesn’t require references or similar? Pre-load text formatted notes? Just write with a lot of of notes like “confirm dates for this reference so I look less stupid later?”

I know I’m writing different things (more smaller/technical than fiction) but your works come off as “research required” at times and wondering how this fits in your workflow.

@MacBalance I am waiting for an opportunity to find out! Because I normally write on a Mac, but am a bit wary of pulling out an M3 Air in a pub/coffee shop (easily spilled hot liquids ahoy!).

Yes, research is mandatory for my work, but you can just type TK and come back to it later …

@cstross @MacBalance if you're worried about distractions while doing research, one solution would be to loard a Linux or Mac laptop with the entire Wikipedia offline in ZIM format (about 100GB), using the Kiwix app, and disconnect. Or get a cheap Chromebook, install the GalliumOS Linux distro on it.

@cstross so, there are no doubt nineties journos who'll tell you it sucks compared to their memories of the beloved device?

@pdcawley The Z88's devastating weak spot was that everything in its RAM was lost if you swapped AA cells without plugging it in to the wall wart first. The EPROMs were a poor substitute for non-volatile storage. But since about 2000 you can buy FLASH memory and OS 4 lets you selectively erase/write to them in any slot. So up to 2.5Mb of non-volatile working storage is now A Thing, plus 512Kb of RAM (there's a 512K RAM/512K flash card).

That would have been amazing in 1989.

@cstross It's a rare product that so spectacularly hits the sweet spot of its uneconomically small target market, isn't it?

Delighted to hear that it's being kept alive.

@cstross My father and I, and two friends from our local Mac Users Group, created Zero G Computers to resell Z88s. But by the time we were ready they had decided to market and sell directly, so we never sold one. I still have a couple at home, though.
@cstross ooh, it's been a while since I've tried to get a japan-market gadget directly from the US. If it "rhymes" that well with the Z88 (one of the first toys I got with my first post-college salary, and actually used for writing on airplanes) it looks like I would enjoy it...

@cstross I'm still waiting on hearing how it goes with Debian, but so very very tempted if it works out!

(Why yes, I will be installing LaTeX and GHC if I get one...)

@flippac @cstross Oh no, don't tell me that. I might just have to get one.

@gordoooo_z @cstross If it helps any the aspect ratio and resolution is not good for viewing anything except maybe slides you produce with LaTeX? But yeah.

(I honestly think if your slides aren't readable at that resolution given the right optics, your slides are the problem)

@flippac @cstross I was referring more to the Debian bit. I've been wanting a little Linux mini-laptop/palmtop type thing for a while.

As far as LaTeX goes... my hands-on experience with it is setting the font size and probably making a title page. LaTeX equivalent of "Hello, World!" 😅

@cstross I don't know if I'll have any luck with the pitch, what with my being nobody of consequence, but I'm trying to convince people at Sharp to talk to the Pomona people. The Sharp Memory LCD displays are basically perfect for this, apart from the fact that they don't come any bigger than "tiny".

@cstross Really nice! I wrote a blog post (in Swedish) about writerdecks, both commercially sold abd DIY. I knew about the other version of Pomona, but not the one you wrote about. Thanks!

@cstross That looks like a very sensible little device. Far more than the original Freewrite, which just... I have so many thoughts (caveat: and zero hands-on time; just lots of opinions).

For starters, as much as I love a full-fat keyboard, I can't imagine using one in a coffee shop being very distraction-free, given the regular interruptions by curious strangers (or annoyed ones asking me to be quiet). Chiclets just make sense.

That it looks like 90s era Sharp/HP palmtops is a plus, as well.

@cstross
Cool. Keep us up to date on how that goes.

I've been considering buying a used Thinkpad and putting #HaikuOS on it with #libreoffice for writing on the road.

@KarlSchroeder The DM250 is a good distraction-free writing tool; I haven't put Linux on it yet (and won't for at least a couple of weeks, if ever). But if you like LibreOffice, a burner laptop with Linux is definitely the way forward. (Not sure about Thinkpad battery life, though.)
