@@Kalvinjj The Intel 13900KS has a power limit of 320 W! Way higher than anything before! That’s how it hits 6 GHz on two cores and 5.6 on the remaining ones. Many other current Intel CPUs have a power limit of 250 W!

[@JayOhm]

To be fair, there are modern processors that are much more powerful and consume even less power. They just aren't meant for "general purpose" computers in the modern sense. ARM1 consumed around 100mW at its 6MHz / 3MIPS, and that's just the CPU, while e.g. STM32L0 chips are more like 20mW at 32MHz / 30MIPS, which includes RAM, flash and some built-in peripherals, and can go as low as 0.2mW/MHz, over 100 times more energy-efficient than ARM1.

My father was asked to get a computer for a family member overseas around 1985 or 1986. I recall an Acorn computer (not sure what model, although it seemed really advanced for the time, compared to our own 1979 TI-99/4A computer) arriving our home, and our family (mainly my father and I) testing it out before it was taken/sent to our relative. I recall using a drawing/painting software to create a colour image of a house (which was quite simple compared to something you might create these days, although pretty good for an 8-year-old child at the time, I think), working diligently on it for a few hours into the late evening/night, before going to bed. I had fully expected my picture to be lost to our family before the computer was despatched to our relative, but the next day, I found that my parents had found a way of recording the image I had spent so long on on to a VHS video tape, which I was very grateful for!

One of the things that is really interesting is that the BBC ran Acorn ARM based systems to generate on screen TV graphics right up until the cutover to Digital TV. The systems were highly efficient and fault tolerant and if in a failure state could be rapidly reset, all highly important for something that operates in real-time.

[@akulkis]

Custom applications can keep all the code and invariant data in ROM, and often have no need for an operating system, so it's not surprising that when reset, the application in the appliance is fully operational before your finger even leaves the reset button.

The were amateur microprocessor designers. Mind you, if anything, this might've been an advantage, as they went in without some of the existing preconceptions that other more established designers were using. It didn't hurt that they also took a leaf out of Chuck Peddle's book, as the internal design of the 6502 and its ISA were major influences on those of the ARM.

[@catriona_drummond]

@@talideon Still, amateurs strikes me as rarther clickbaity. I wonder if he said "amateur" to Furber's face in the interview.

[@kyle8952]

@@talideon "Amateur microprocessor designers" is a false concept. They were all qualified to design microprocessors as much as anyone else in the world. They had cut their teeth before microprocessors were even widely available. When they decided to make ARM they had designed several computer architectures, their own sophisticated operating system, their own programming languages. Not only were they qualified to build ARM but they also chose to build custom hardware and software for the purpose of then designing ARM, because they correctly appraised everything available to be worse than their own prior work. They didn't go into the ARM project without preconceptions. They had very strong preconceptions. Firstly they had evaluated every microprocessor on the market using their tube system. Secondly, they were academics, and closely followed the latest computer science developments. They knew from watching the Berkley RISC project that a team of their size, budget and experience was more than enough to design such a CPU. It was already a settled question for years.

[@dr_jaymz]

The term "Amateurs" is really a metaphor in this instance. The video shows reasonably accurately that they went to see "professional" designers and realised that there was a very low bar to entry and that they felt they could do better. They also mention the fact that they still had some doubt in the mind that they could actually do it because they felt like they would be "amateurs" in comparison, as if they were missing something. If we can do it, what is stopping everyone else? > 300Bn of them have been produced and production rates are increasing rather than a central processing unit they are more commonly embedded into everything. A car might now have 30 of these cores embedded in everything from the seat to the AC system.

[@johndoh5182]

Clickbait? The people involved in moving to the development of ARM were engineers. Calling engineers "amateurs" is pretty out there. They had been studying different computer architectures for years before they developed ARM. MAYBE there was a new guy on the team?

[@multiplyx100]

Yeah, this is like calling IBM amateurs when they created their first processor. Or Intel, or anyone. I don't think anyone except Acorn ever created computers with a multitude of second processors. They were up to their eyeballs in this stuff.

Last year I wrote a Basic program that calculated prime numbers and I ran it on both an 8MHz Zilog Z80 and a Raspberry Pi Pico. The ARM chip on the Pico only took a few seconds to do what the Z80 did in minutes. If I recall correctly the Pico was easily 100x faster, and it wasn't even using the second processor core. It's incredible how fast low-spec computers actually are these days.

[@low-key-gamer6117]

You compared and 8bit processor that has no modern facilities to modern dual core processor and are claiming that the latter was superior? Are you dumb?

[@acmenipponair]

To be frank, you compare a CPU with 133 Mhz (Raspberry Pico) with one that was running on 4 Mhz. And even if that's Pico not 100 times faster, you should remember that the OS will take around 1-2Mhz of your Z80, while it will only take around 10 Mhz of your Pico, so you have then 2 Mhz vs. 120 Mhz. It would be ashaming, if your Pico wouldn't perform 100 times faster than the Zilog Z80, especially as it's a 32 Bit controller = so it has to start shifting around bits for still being able to calculate the numbers much later than an 8 bit processor.

The main advantage of x86 is it's an insanely popular platform that is also relatively open. The mandatory IBM PC compatibility guarantees that every system will be able to boot any sort of OS you want and have some basic features like VGA/Vesa graphics and keyboard/mouse support etc.. To see a x86less world, all you have to do is take a peek on how things work on android. It's pretty dire.

[@GyroCannon]

@@dan_loup That's something that is rapidly changing because of Apple's push with ARM. As software (particularly device drivers) get ports for ARM, we'll see less and less issues with compatibility as time goes on. That said, you did remind me that we have a crap ton of legacy systems that companies and governments are unable to / too cheap to replace, and no one is going to start modernizing those. That alone is the only argument for keeping x86 around in the long run.

These more educational videos have been pretty amazing so far, keep it up! Also, my university uses ARM for its computer engineering course, and it is safe to say that ARM is the future. Extremely powerful yet efficient processors should be the future in my opinion, which ARM is doing.

[@SuperUtilisateur]

RISC-V seems more promising for the future. More free instructions sets will probably allow more research + things like Intel's x86 licensing or the fear of ARM acquisition won't be possibilities.

The first time I saw an Archimedes, back in the late 90s, my mind was blown. It could run things much more recent, much more expensive computers could barely run. Yet it was very obscure.

I respect the ARM instruction set, it's got something like half the registers of MIPS, but that's one more bit for each operand that can be used for more opcodes instead. It's seems like the right balance.

[@nezbrun872]

I do MIPS and ARM (Cortex M) too, in assembler when necessary for the odd pinch point: my line of work is embedded DSP for RF systems. I agree that the relatively small number of registers on ARM can certainly become a bottleneck when you're trying to do an algorithm in-register to minimise load & store operations.

[@jgharston]

[@mudi2000a]

I still remember when the Acorn Archimedes was released (which is probably covered in the next episode). And then I was disappointed it never took off back then. I thought it could become like the next Amiga. Also I remembered DEC ( when they were not yet Compaq/HP) were also playing around with it (StrongARM), probably for a thin client or set top box. I think they totally deserve the success that now ARM has become the core of incredibly powerful and efficient processors like the Apple M series.

@@Underestimated37 There's true real time 3d on weaker hardware like the Amiga, ST. and even the ZX Spectrum. Granted, 8-bit 3d is usually more impressive than playable, and even ST/Amiga 3D is really compromised (No Second Prize is the limit of what you can get at a solid frame rate, though Hunter has its charms), but yeah, the Archimedes was the first western computer to make it a viable potential alternative to 2d. Still, it wouldn't be until the mid-90's that the potential was really realized, and you had the power to execute a 3d version of every 2d game. And it was still a questionable goal until the late 90's, early 2000's.

I was unconsciously tensing about how Sophie Wilson would be handled, especially since Micro Men went the other way (she had a cameo but I don’t know if she had any influence on the rest) and I know Furber had said Sophie in the present but (redacted) about the past. I mean, I would hope that was with her blessing, but it is certainly a more old fashioned thing among trans people. So props for how you handled it, I assume you had Abigail’s input as well as her voice! I hadn’t realised the “sell first” part came from Clive but it makes total sense. ARM is indeed very cool. The last time I saw Furber talk about this was before Apple made all their computers use ARM. Can’t say I’m surprised he brought it up now though lol

[@nezbrun872]

I guess it depends whether or not historical accuracy is important to you: I worked with a handful of Acorn employees in the early- to mid-80s. Personally, I did prefer the Micro Men portrayal of Wilson bearing in mind the timeframe under analysis both in that documentary and in this video. I assumed the choice here was to avoid unnecessary confusion later on when Steve Furber is interviewed, and his comments on Wilson. Early on in the video it was a significant discontinuity for me, but then I already had some knowledge. An individual's gender is actually irrelevant to the story itself, but I am sure that someone will find a way to use it to promote an agenda. The work both Furber and Wilson achieved on ARM creation and development is testament to their brilliance. For their achievements to be still so relevant today is testament to that. It is also especially gratifying considering the diminutive size of Acorn when this originally happened. Just my thoughts.

[@kaitlyn__L]

@@nezbrun872 that’s one reason I’d really like to know if the “man back then, woman since” way of speaking is personally preferred (or at least endorsed) by her or not. It’s a thing people can be very different about, I go back and forth on it for myself. I understand that there’s the element of “what did people say back then?”, and frankly the portrayal in Micro Men is clearly that of an “egg” (trans but unaware) anyway! (Plus there’s plenty of other embellishments in that production, so it’s a sliding scale really.) I also suspect they just didn’t want to take up valuable time (these videos being short) on what is as you say irrelevant to the rest. So this way is the safest option, for a few reasons, to just pick one name.

[@LowSpecGamer]

The questions I was making while writing the script were: “How do we portray her in a way that is respectful both to her and to trans viewers?” And a lot of thought went into implementing the video around those two questions. Our Artist came up with an androgynous design that I think worked well and I made sure she was referred by just last name on all in story dialog. It is a hard needle to thread, but we did our best. The original script of the video did had a bit more of a more direct cal to our decision of calling her by her name, but I removed it while editing because I did not want to derail the focus away from her absolutely incredible technical achievements which should be the center of this story. I hope it was the right call.

[@kaitlyn__L]

@@LowSpecGamer this is pretty much what I thought (indeed when I first saw her design that’s what really piqued my interest in how the voiceover would handle it); and I think you threaded the needle very well (especially given the runtime considerations)!

I already said it before. But I would absolutely love to see a video about the 90s Famiclone revolution in the Second and Third world. Really fits the theme of using cheap hardware and skilled devs to make a gaming icon. Though it sounds a bit research heavy considering it happened semi independently and slightly differently in every country. I mean, you grew up in Venezuela right? A bit of googling shows there was a Venezuelan Famiclone. I assume you know about it considering I know about the Israeli Famiclone (nicknamed Megason after the name of the importer) despite being born a decade late for famiclones.

[@Mr_G977]

As I worked, at the time, for the Ministry of Defence UK, I was one of the earliest users to try out the first ARM chip pre-production as a second processor with a BBC Master. Steve and Sophie both understood that who ever produced the most Mips (Millions of instructions per second) per mA of current could win the race for mobile computing where power consumption is critical. Part of the genius and forward thinking was to use the 6502 CPU as the first processor but place it in an architecture that could leap frog the then emerging 16 bit computing with a 32 bit capable address space and networking with a second processor.

This is a total misrepresentation as if Furber and Wilson were working in a vacuum. There was a team of half a dozen VLSI designers at Acorn to implement the specifications of Steve and his team. Wilson was a software guy, and not involved directly in the hardware implementation. We were all experienced professional electronics engineers, and I think we would be all offended to be called amateurs!

Agree. I'm frequently appalled by the re-writing of my experience. I'm an electronic engineer and was a VLSI Design engineer at TI Bedford (Warren East was a colleague on LAN team). I was a friend of Colin Watters and his wife - as you say, Not amateurs! I attended the launch of the Women in Science and Engineering campaign in 1984 with her and remained friends when she was at Arm and Colin still at Acorn. Hauser was never supportive of women engineers until he decided to champion Sophie as the UK top role model.

There are several mistakes in the video: 1. I am not sure that that Acorn hired exactly _Sophie_ Wilson, hence certain inaccuracy in dubbing. Hermann Hauser still can't get his head around the transition! 2. The multiprocessor architecture of the Beeb was planned from the beginning, as several factors were in favor of that: (a) the architecture was originally built as a multi-processor system to power gambling machines (a very shady but lucrative deal with local mafia); and (b) when accepting Acorn's bid, BBC insisted that Z80 expansion is a must. 3. The Z80 expansion was actually sold, capable of running CP/M 2.2. 4. ARM expansion of the Beeb was not really available to the market. It was more of an early devkit for Archimedes software developers.

[@LowSpecGamer]

1. It is generally considered in bad taste to deadname people, so we tried being tasteful on that. 2. This actually unclear. Some interviews point at the fruit machine as creating some of the ideas for the multiprocessor design, some point at Sophie coming with the idea along with the Tube connector. The exact genesis of the dual processor design is probably one of those ideas that came from many small elements. I would be interested if you have a source on BBC requiring the Z80 module because that I never read anywhere. 3. I know! Several other processors in fact. It was just not relevant to the ARM story. 4. Correct as far as I understand, but this video finishes at first prototype. What happened when they tried to commercialize is a topic for the next.
