Is software for 32bit Acorn hardware dead?

Post by Naomasa298 » Sun May 24, 2020 12:40 pm

Most of the programming talk on the forum is about 8-bit software.

Is software for 32 bit Acorn hardware (i.e. Risc OS) dead? Has everyone move on to Raspberry Pis?

No Software isn't dead. just most 32bit people live : https://www.riscosopen.org/content/

As pointed out, 32bit folk live over on the ROOL forum. Posts here are generally about Archimedes through to RiscPC.

The forum channel names are a bit misleading in this respect, in that ARM2/3 which are the bulk of the discussions here are a 26bit address bus, it's only the registers and data bus that are 32bit. In Acorn community terms, they're generally referred to as 26bit Acorns to save confusion.

Admittedly things get more confusing with the RiscPC and A7000 which are 32bit capable, in which case we go by the OS bitness - everything pre RISC OS 5 including RISC OS 6 is 26bit. RISC OS 5 is 32bit and has its own forums over on ROOL.

We could easily rename our 32-bit forums to 26-bit if folks think that would be helpful?

My take from the posts I've seen and made, FWIW, is that any posts to our 32 bit sections are generalised to the Archimedes range and are not specific to the bit count!

I don't think changing the number from 32 to 26 would make any difference and may even confuse!

Interested to hear other opinions . . .

26-bit didn't even become relevant until the Iyonix turned up, and to most people the ARM platform is 32-bit because that's how wide the data bus, ALU and registers are.

I'm inclined to agree that it's confusing for newcomers... it's only really relevant if you're running RO on a modern platform like a Pi, and even there you have a bunch of CPU-specific gotchas related to unaligned loads and stores.

"32-bit pre-Iyonix, Beagleboard and Pi" is possibly a better distinction to make, if you have to make one.

One distinction would be between Archimedes era machines and the Risc PC era and later. The A-series machines can only run 26-bit code, as I understand it. The later machines can run 32-bit code if there is OS support for it. Am I remembering that correctly?

Alternatively, it could be between original/retro RISC OS and "modern" RISC OS since that will also determine whether you can run 32-bit code. So, maybe between pre-/post-RISC OS 5, though there is the ROOL forum for the modern stuff.

Is RISC OS 5 still a thing?

Yes it is. RISC OS 6, not so much.

What's the best platform to run RISC OS on?

If you don't already have a suitable Acorn machine, a Raspberry Pi is probably most convenient. There's a laptop, the ARMbok.

But you might well be asking about the best retro machine?

Thanks. Would be nice to see RISC OS again but I expect there are huge incompatibility issues with earlier Arc /RPC software. presumably you'd need another emulator within RISC OS 5 to run the older games. I notice RISC OS still seems not to multi-thread.

You could use emulation, but a better option would be to use ADFFS and download games JASPP has the rights to release via PackMan.

Update RISC OS on your Pi, as per the Pi requirements for ADFFS 2.72 and add the following URL to PackMan:

Code: Select all

http://www.jaspp.org.uk/packages/release
Either manually extract and run ADFFS, or let PackMan download it when you install the first game - just make sure you run it before launching a game.

I'm probably somewhat biased, but I think games run more accurately on a Pi than on the original machines as timing and sample rate issues are no longer an issue and you can use USB Joysticks. All the games on the YouTube channel in my signature are running on a Pi with ADFFS.

You're advising to get a Pi?

I tried RPCemu on Imac but didnt get far. Probably because the installation was confusing.
