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.

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 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.

@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.
