Psion 3c was what got me into programming! My grandfather gave me his old one when I was a kid. To an 11-year-old, a spreadsheet, world clock, and address book gets old pretty fast :) But the in-built OPL [1] language provided unlimited possibilities. You can see the icon for it in one of the screenshots. I remember printing off a copy of the 300-page language manual I found online (breaking dad’s printer in the proc…

Exactly the same here. Stole my fathers Psion 3a and wrote a lottery number picker in OPL. IIRC, it even had pretty great syntax to easily draw the various default OS UI elements.

The ability to write the application and then run it on the same mobile device was such a rewarding feedback loop as a kid. There were some pretty good books on OPL in the 90s too.

The standard of the third party gaming ecosystem for the OS (EPOC) was shockingly good for the time as well really, there was an amazing golf game, also written in OPL. That Steve Litchfield name I remember a lot from the era, he was extremely active developing OPL software:

I have used a boox tablet with a Bluetooth keyboard (actually an iPad keyboard with hinges) there is nontrivial latency while typing, but I found it was quite manageable. It just forces you to keep more of the command or line of text in your head. I found myself writing on it a lot. Even did a little programming.

Interesting, when or which device did you try this on? On my Boox Nova 3, typing via the BT Keyboard is pretty much instant, no noticable delay. Though in Word or Outlook it helps to choose the faster screen mode. No issues in Termux though.

Lots of focus on the hardware here but its form factor still exists in niches. What has vanished, is our ability to do general-purpose computing at ~8MHz. Consider the computers you had in the 90s. Windows 3.11 and Office ran on a 286 but I sit here with 12 cores at ~4Ghz just to post this crumby comment. We are spoilt. It really makes me yearn to do more with less.

So sort of, but let's not look at the past too wistfully. I also remember when moderately long text had to be split across files (even multiple floppies if you were writing a book). I remember having to choose what languages my OS installation was going to be able to display.

What changed?

Modern Windows still requires language packs, but you can apparently switch your primary language without a reinstall.

Adobe products still corrupt already-correct Arabic text unless you have the correct edition or add-on or something.

It was indeed annoying to transfer files at least until the Internet and flash drives were widely available, but that’s been more than 20 years.

I know there's XKCD for everything but I wonder if there should be.

No. I bet you could make a slightly better one and increase diversity in the online humor world.

These limits of old hardware are exactly what makes the software so amazing.

Look what was achieved despite those limits. We've basically had the same desktop and productivity software for 30 years. Look at games like Doom or Tyrian, or what was happening on consoles and think about how crappy that hardware was.

Modern software is embarrassingly slow by comparison. I've been around long enough to know that's always been the way. Newer software drives new hardware sales and we're on yesteryear's supercomputers but why?

2MB is 2 million bytes, The average book is something like 0.5

This is a bad thing?

lol, irrelevant!

I have no idea what you just said. People for the most part read/write text and watch videos. This would work much better if we eliminated compute entirely.

> I enjoy using the old hardware but it really doesn't do most of the jobs we have now.

imho the way to look at old hardware is to look at only the good features we've lost. For example, I cant think of anything I want from a c64 except from sprite collision and having menu entries starting with function keys [F1] because that worked so insanely fast compared to a mouse. The rest was just coping with the state of the art.

On a positive note, HN is one of the very few sites left which is still simple enough to be used with older browsers. I am writing this comment in the text console (no X11) of a Raspberry Pi 3 with a braille display (no monitor connected) as the output device. Using lynx as a pretty reliable browser. It is the exception, I know, I am a freak by nature of my disability, but I am also proud to know this niche still exists and it is actually possible to do some interesting things online with very little resources.

So, motivated by this article, I checked eBay, expecting to burn $20-30 to get one and found that these sell for around $100 (thank god, didn’t buy another device to add to my pile). My question is: who buys these at that price and for what purpose? Collecting old devices? Using them? I don’t think buying these have the allure of retro computing, eg buying a Sinclair Spectrum.

I bet some people still use them. I used my Psion 5mx as my primary organizer until only a few years ago, and I still kind of miss it. It still works, but lacking any kind of connectivity except for infrared, it's increasingly difficult to justify in today's world.

*"tested"/"run during development exclusively"

You still want the text editor and more importantly compiler to run on beefy workstation hardware, in order to avoid programmer productivity problems like long compilation times[0] and to take advantage of CPU-intensive optimization techniques.

Agreed! I wish there were widespread ways of throttling CPU and memory given to desktop applications today. If I'm testing a web application, I tell Firefox to throttle my network down to GPRS and see the responsiveness (or lack thereof) and once my work is done and GPRS is reasonably fast (or whatever) I can give a quick glance at normal 4G speeds and see my web app screams now.

So why can't I lock a desktop application to settings like "an unused 386 PC with 24MB of RAM"?
