Acorn Archimedes RISC OS on Raspberry Pi 400 

PinnOS will let you install RiscOS 5.24 as a partition too (not the RO Direct .iso)

Can RISC OS from 1987 run unmodified on Raspberry Pi 400? CPU instruction set compatibility doesn't build the full legacy software support. X86 PC's unmodified OS from 1987 can still run on modern PC hardware with up to UEFI Class 2. My AM5 X670E motherboard still has CSM.

I never had an Acorn (or used one), but I think the Acorn was probably the equal to the Amiga. It's a pity the worst systems ended up becoming the ones that became predominate.

I had an Kinetic RISC PC and a Iyonix from Castle. They managed to keep the platform alive for a few years and thankfully had the vision to open source RISC OS

But even better, it's running on a native descendant of it original processor. The Raspberry Pi was even created to try to fill the void left by the Archimedes! This is more than retro. This is like a Commodore running on 65816. This COULD have been were this system ended up anyway. Nevermind that the Archimedes inspired the Amiga and Atari "flat: systems. Being from the states I never got to see an Archimedes until the 2000's. Still have never seen one on person. There is rumor of 60hz models made for US power, but at the time the machine that would unquestionably win the proccessor war, as the projecter of almost every smartphone, tablet, andeven the latest Mac!

@@Ratteler I don't think the A3000, released in 1989, inspired the Atari ST or Amiga 500, released in 1985 and 1987.

@@davidste60 I think the look at the hardware is missing the point the amiga was the one of the first PC's to come out of the box new with full work OS desktop, with a mouse), not some sort if add on (even apple Lisa didn't have desktop, it was more of a very fancy electronic typewriter, the desktop was very basic, nothing could be customised at all, the was the zerox machine with a mouse ( not called a mouse I think) from the demo's I've seen go wow even today, when PC's only had a DOS prompt !

@@dh2032 I think you've missed the point. Ratteler said that the Archimedes inspired the Atari and Amiga computers, but those came first. It's about the timeline.

RISC OS Direct is not the 1987 original RISC OS release. Retro unmodified MS-DOS 1.0 from 1981 can still run on modern X86 PC hardware up to UEFI Class 2.

Hard to pay attention to everything when you’re recording a video. I will give it a download though.

Thats right.....everywhere else in the world was commodore....only ppl in the uk were desperate enough to use it.

In Norway lots of schools had Tiki 100 computers; fairly low-end stuff but developed in Norway... default/most commonly used programming language was LOGO... Acorn computers were used in some special needs schools and institutions I believe, due to the ease of interfacing with custom hardware, though that was mostly back in the 8-bit days of the BBC computer and later the Master variants.

I had an Amiga, and most of my friends (in Norway) had either Amigas or game consoles. The only experience I had with Acorn was the few times they were mentioned in CU Amiga Magazine...

Ah yes, Krisalis. Your games were played in many a school during breaks and lunchtimes. MUFC Europe was one I remember.... Edit: oh, and games were pirated on 3.5" floppies

Yes it was. It's very sad that the Archimedes lost out to the ST, Amiga and then to PCs. How the world could have been. I suppose in a way it's coming full circle now. ARMs are getting more powerful, powering Macs and (slowly) moving into servers. It won't be so long until we all have ARM desktops/laptops running Windows (or RiscOS?) to go with our ARM phones, watches, etc.

It was Lander, and it became the game Zarch, later converted to other platforms with the name Virus.

Sounds very similar to my high school. We had 2 computer suites which had a mish-mash of A3000s and A3020s, with 3 or 4 A4000/A5000s, and a handful of Citizen dot matrix printers, a random Canon inkjet and an ancient plotter. Each of the CDT and science labs usually had 2 or 3 BBC Micros sat in the corner collecting dust, which the library had 4 random Win3.x PCs, no two alike. IIRC we had one 286, one 486 and two 386s, one of which had a CD-ROM drive. They were the only PCs in the school, and were used pretty much exlusively playing Worms, and a basic range-finding canon fire game in Windows, oh, and The Incredible Machine, which I *LOVED*. Weirdly, the best specced place in the whole school was the hardly ever used careers library, which had at least half a dozen top of the line, brand new double-pizza boxed RISC PCs, complete with x86 processor cards and CD-ROMs, and gorgeous multisync monitors and HP laserjet printers. They were only ever used to run a "choose your career" program in MS-DOS...while the CDT graphic design lab stuttered on with the A3000s and a plotter dating back to the early medieval period.

@@lmlmd2714 now a primary aged child would be horrified if they didn't have a system with at least 8GB of Ram and the latest version of Windows. Upon said system they'd open Chrome and use it to run a web-based app to do their homework. Imagine the excuses nowadays "Sorry miss: our fibre broadband went down and I couldn't log into the group remote learning seminar as my mobile had the wrong version of Android on it.... I'll submit my colouring in by the end of the day once my brand-new mobile handset is delivered by an Amazon drone"

There's AROS as well, which is (I think) a rebuild of the Amiga OS. It's pretty broken, but you can run it, kind of.

With regard to RiscOS, we are rapidly approaching the point where operating systems are irrelevant. We're actually already there. 99% of people only use their computer to connect to the net. I expect a return of a lot of systems, and an explosion of news operating systems.

The computer is just a showcase for the CPU. There are no famous custom chips on the PCB. So not really wrong.

Well, he was almost right. ARM processors and microcontrollers can be found in just about every home and school, as well as in vehicles, industrial equipment, scientific instruments and who knows what else. I doubt the original designers at Acorn could have foreseen the impact they would have on the world.

I also recommend the third-party app Default Folder. I use it basically just for one function: While in an Open or Save dialog, I can click on any open windows in the Finder and it will select this folder in the dialog. Have been using it since MacOS 9, I think.

It was excellent. I bought a copy back in the day, used it any time I needed to do illustrations for college, although I didn't have the skills to produce graphics like the demos! Corel Corporation bought up the licensing rights for it in 1995 and sold it for Windows machines under the name CorelXara, that put an end to the original Acorn version. Corel has a long history of acquiring or eliminating competitors, even those established on other platorms. Xara (formally known as Compuer Concepts) reacquired the rights in 2000 and continue to this day to sell the Windows version.

Lander is a very limited demo of Zarch, most of the gameplay is missing. Zarch was ported to other systems under the name Virus... It Really showed how much more powerful the Acorns were when it came to 3D stuff. 3D games on the Archimedes were amazing. :O

@@MixelsLab Yup it was called Virus on the ST and Amiga. By far the most superior version was Zarch due to the colour and speed!

X68000 seems pretty sweet too, some crazy games on it.

32 bit!

@@leeshepherd6512 I do apologise Lee, it tend to forget that. The 16bit generation was in full swing when it came out, so often gets lumped in with them. Another injustice corrected. 😁

Yeah, Top Banana was really out there

I always had Atari at home (still do!). I feel the Falcon had so much crippled potential. It was a really powerful machine but Atari really hobbled it with the 16Mhz bus and ST style case. People have done some amazing stuff with it over the years though and feel it really deserved a better chance than it got - but yeah, to be brutally honest, much as a I love Atari - it's true the Acorn machines were much more mature and less compromised designs - the advantage of having a large institutional de-facto captive market and lots of vendors on board from the get go, which Atari really, really didn't get the importance of.

Well, RiscOS isn't an OS supported directly by the Pi Foundation, they have enough on their plate with Raspian, so it's no surprise they only provide a plain vanilla version. The primary distribution on the RiscOS website is generally bereft of third party software too. I dare say they have limited time and resources which are better spent on keeping the OS itself up to date.

thanks for the info

Iris will be an incredible browser and it will be free of charge. It’s still in beta at the moment but it should be released soon.

I worked for a guy who was selling them. Unlike the OP I didn't like that you had to manually adjust resources; like space for sprites, etc! Seemed pretty arcaine to be?

logo? was that the programming language?
