Sure. I bought back in the day a G4 Mac Mini just for that purpose (running both Linux and OSX) :-)

In which case do you need to test big endian? Compiler or low-level library development?

Mainly for networking or disk storage, and in general for anything involving storing integer data into raw packets that will reach different CPU architectures (e.g. load or store an integer from/to a memory buffer into/from a CPU register).

I don't know about the Amiga stuff, but as PowerPC board for running Linux looks great: "The e5500 is a superscalar, dual-issue core with out-of-order execution and in-order completion. It maintains the seven-stage, four-issue pipeline that is a trademark of the e500 family, but is able to provide additional performance, by scaling up to 2.5 GHz." [1] [1] http://www.nxp.com/assets/documents/data/en/white-papers/64B..…

Yeah, my first thought was "this board looks great for testing big-endian". Would be nice to see comparisons to e.g. the G5.

At what point will all big-endian usage be just developers testing big-endian with no users to use the results, and at what point shall we stop even testing?

(Yesterday, I finally got around to making encoding_rs work on 64-bit big-endian systems by testing PPC64 in qemu. Then I timed out trying to get a 32-bit big-endian system with recent enough glibc to run Rust up and running in qemu, so I still haven't tested the 32-bit case... Unclear if anyone even cares.)

I was going to be short. Still, even if large, I won't price this above two cents. I am saddened to say, but everything that made the Amiga great when it was launched seems meh by today's standards. Amigas had preemptive multitasking before any other home computer. Today it's the norm. Amigas could switch video modes every scanline. Today, even the concept of a scanline takes a while to explain to someone born in the…

> Hardware accelerated graphics (their blitter was cool) is also the norm (and many orders of magnitude faster now).

Not really. Current GPUs don't have 2D hardware, everything is just done in "software".

> I'd imagine, for starters, a uniform CPU/GPU architecture. Lots of cores accessing a single memory pool (let them have some scratch memory for themselves to save bandwidth) running the same software doing the job of both CPU and GPU. Make this CPU/GPU hybrid monster capable of combining multiple 4K inputs piped into textures and composite them in real time on any display surface available.

Sounds rather like Larrabee [1].

Does anyone remember CygnusEd? To this day nothing I use scrolled as nice as that text editor did. Such fluid scrolling. Sigh.

LOL. Yes. That's what inspired me to write my own Windows text editor with smooth scrolling: http://deadfrog.co.uk It's a bit rubbish. It is written in the Amiga style of every-byte-matters though. If it wasn't for the embedded Python interpreter, the entire install would be about 300k.

> It is written in the Amiga style of every-byte-matters though.

This needs to be in the marketing of your website!

It sounds like you're focusing on programmers, and I think they'll get the nostalgia of "remember the days when every byte mattered?" With the 1TB drive in my laptop I don't actually care about app size, but I love that you have a 1MB text editor in the days of Electron-based hipster minimalist text editors that are over 400MB.

The story in your release notes about resisting adding a hi-res Vista icon because you thought 260KB for an icon was obscene, that story is both hilarious and awesome :)

It looks like this is mostly just a fun project for you, but as a potential user I'd love to see more screenshots, an EXE installer option instead of .zip, and a big download button on the front page so I don't have to dig through the site to find how to download.

But most of all, I think it's hilarious/awesome to see a text editor with a "Frames Per Second" meter! :)

With IBM's huge investment in better support for little-endian PPC (in hardware, in software development toolchains, and in software itself) it seems likely that many PPC users are going to slowly move away from little-endian. I can imagine some embedded uses, e.g. in network hardware, may well stick with big-endian because it fundamentally makes sense there, but I imagine it's going to become increasingly obscure.

The Amiga has a small but really enthusiastic fanbase that doesn't want to admit that it's dead. That's it, as far as I can tell. All of the modern Amiga hardware seems to suffer from similar issues to the ones mentioned here - it's expensive, slow by modern standards, has strange and annoying hardware and driver issues, and there's just not much software for PPC Amiga. It can't even run modern web browsers. (Unless…

I had a maxed out Amiga 500 (with sidecar expansion) back in the day and it was awesome (for games and 2D graphics) in 1988, amazing in 1990, and then Commodore ate it owing to monumental incompetence. Even at the height of its technical superiority, it was crippled for serious work. Its pixels weren't square in any graphics mode, and in the highest resolution mode you needed to endure flicker unless you had a specia…

I don't know why you were downvoted because you're describing a major problem the Amiga had in the creative industries of the '80s and '90s.

Back then almost everyone was still designing for print, and the Amiga just wasn't cut out for that. It was a multimedia machine before there was any way to distribute multimedia to anyone else than other Amiga users.

Video production was a niche that was compatible with the Amiga's design, but working with analog video wasn't going to be mainstream ever... and for digital video, the Amiga was fundamentally underpowered.

Can someone tell me what makes "real" Amiga so wonderful that it's worth paying $1500 for an objectively outdated computer? What does legit Amiga do that something like, for example, AROS doesn't do?

I totally understanding the beauty of the system; what I don't understand why they don't move to something like AROS, which is open source and runs on (substantially) cheaper hardware.

Thanks. Hilarious/awesome is about what I was aiming for. Your comments are very sensible. I'll see what I can do.
