xyzzy3000··on Can Intel finally beat ARM on performance per Watt?
No, I disagree with you here - it isn't one user and certainly not an abuser. This is reputationally damaging, and doubling down is not helping. Arguably, the doubling down is the most damaging part.

An absence of open expression of disapproval is not the same as approval - people may just be avoiding dogpiling a member of our community.

I would add that people have a right to express disagreement or disappointment in a respectful manner in accordance with the rules of this moderated private space, and we have not had moderation/interventions suggesting otherwise. The criticisms are reasonable, to my mind at least, and probably ought to be taken as a massive hint that something is wrong. We are less than a day in, and it's not too late to fix things.

I am trying not to be too critical, as I have enjoyed previous content from this channel and I wish the poster well for the future.

The car in the article has the steering wheel on the left, which is the wrong side for vehicles driving on the left-hand side of the road. Domestically-produced cars in both the UK and Japan have the steering wheel on the right.

xyzzy3000··on Tiny Core Linux: a 23 MB Linux distro with graphical desktop
RISC OS has the concept of "OS units" which don't map directly onto pixels 1:1, and it was possible to fiddle with the ratio on the RiscPC from 1994 onwards, giving reasonably-scaled windows and icons in high-resolution modes such as 1080p.

It's hinted at in this tutorial, but you'd have to go through the Programmer's Reference Manual for the full details: https://www.stevefryatt.org.uk/risc-os/wimp-prog/window-theo...

RISC OS 3.5 (1994) was still 2MB in size, supplied on ROM.

That's only RISC OS 2 though. RISC OS 3 was 2MB, and even 3.7 didn't have everything in ROM as Acorn had introduced the !Boot directory for softloading a large amount of 'stuff' at boot time.

xyzzy3000··on Raspberry Pi 500+
And the co-creator of ARM, Sophie Wilson, still works for Broadcom - the company which bought part of the remnants of Acorn (Element 14). This is where Eben Upton worked before going off to start the Raspberry Pi foundation.

Jack Lang was involved in the Pi, having also been involved in Netchannel, the STB company which used the Acorn technology and had funding from Hermann Hauser, co-founder of Acorn.

David Braben, co-author of Elite (and author of Zarch/Lander for the Acorn Archimedes) was an early Pi supporter.

xyzzy3000··on Raspberry Pi 500+
Acorn Archimedes 400 series, and the 500 series that followed it (in practice only the A540). The original ARM workstations.

The single board computer Pi naming scheme is based on the BBC Micro (Model A, Model B).

As for the 'plus' - Acorn A7000+ was the last of the Acorn desktop computers to be released.

There is a heavy Acorn influence with Raspberry Pi, for good reason.

xyzzy3000··on BBC Micro, ancestor to ARM
The various Sun 'JavaStation' NC models retain the SPARC CPUs of their workstation line - they definitely do not use ARM.

JavaOS was in ROM, on a module that can be removed (SIMM-style form factor). At one point people started to use BOOTP to run Linux compiled for SPARC as a replacement, as JavaOS was unpleasantly slow on JavaStation hardware.

School lab RiscPCs tended not to look as good as this one though - the 'Rocketship RiscPC' with integrated pizza oven and kitchen sink: https://web.archive.org/web/20050305122925/http://www.d1.dio... https://web.archive.org/web/20050207161844/http://www.worldo...

The ARM7500FE is considerably slower (in terms of clock speed) than a StrongARM, but the FPU apparently makes StarFighter 3000 run very well.

StrongARM with an FPU would have been incredible, however no FPU option exists for the RiscPC. There was a commercial software package that would allow the FP capabilities of the 486/586 copro to be used from RISC OS, but I'm not sure how effective it was.

For anyone interested in the very early Acorn era, there are some replica boards available here, from System 1 all the way up to System 5:

I think it was possibly the first to go into a desktop computer.

ARM250 datasheet here: https://home.marutan.net/arcemdocs/ARM250.pdf

For Acorn, this chip really helped to bring costs down for the A30x0/A4000 machines - the Electron of the Archimedes era. The RiscPC equivalent was the A7000/A7000+ with the ARM7500/ARM7500FE, the FE being novel for the inclusion of the FPU which ARMs had traditionally not included.

I suspect that the Pi 400 kit is a nod to the Archimedes 400 series, but I haven't seen anything to confirm this.

Both Ian Bell (Elite) and Tim Tyler (Repton) have fascinating websites of their own. Elite is there for download alongside a treasure trove of historical information, and Tim has a successor to Repton, 'Rockz', which expands on a lot of the concepts in interesting ways.

If possible, get the batteries removed from the motherboards - the leaks cause immense damage.

Rechargeable AA batteries in a battery holder are a sensible replacement.

If the hard drive has packed in then a SD to IDE/PATA adapter is available.

It's an entertaining watch, although a fair bit of dramatic licence is taken when depicting various anecdotes that would be well-known to readers of The Micro User and similar magazines of the time.
