    Great machines. Networks of these RISC PC’s kept many of the BBC’s TV news operations on air. From the launch of News24 to at least the closure of TV Centre in 2013. They ran software by Omnibus Systems and controlled video servers, tape carts and vision mixers for automated transmission. Rack mount machines were available in 3u. And they came back in seconds rather than minutes if they needed a reboot.
    The Education department used 3 or 4 slice RISC pc’s in the late 90’s to do basic offline video editing. They had a capture card and Jazz drive. They were horrible.
    There’s a thriving community of RISC OS enthusiasts and a big meet in Wakefield in April called the RISC OS Show which is worth a visit.

    It really can't be understated how important ARM is. It's the most prevelant architecture on the planet. You wouldn't have iPhones or Android phones or tablets or Raspberry Pi or smart TVs or smart cars without it.

      Of course the modern ARM Architecture v7 and v8 processors have evolved to look a lot more like x86 (they're more CISC now, and have integrated piles of modern CPU features that were firmly established in the x86 world) - but the v4 architecture was pretty brilliant. One of the platforms I learned to program with was the Gameboy Advance - which is ARMv4T (similar to the ARMv4 StrongARM here) and it's a clean architecture that's lot of fun to program for. ARM are certainly doing a lot of things right, and they'll be relevant for quite some time to come no doubt.

    Was an avid RiscOS user until Acorn’s demise. The one thing I still really miss today was the ability to keep menus open after clicking an item, by using the right mouse button. So many applications demand multiple menu clicks to carry out an operation - and reopening the menu is a real pain. This applies to both Mac and Windows - in this respect, both still being beaten by a quirky, ROM-based OS from the 1990s.

      It was, though I always found the NIC was always a bitch to fit because it was so tight to the back of the board if you wanted to fit it without removing the motherboard. One thing that RMC forgot here (or possibly didn't know) was that there were two different PSUs supplied on the Risc PC. The lower power one was only meant for a standard single slice where multi slice machine needed something a bit beefier. And yes, the fans were bloody noisy!

    we used risc PC's in the early days of building management system , our boffin bob (bob the boff ) was very good with the BBC so his transition to risc was easier and he wrote a beautiful operating system for our buildings , you could get custom "poddules" made which could be linked to the outstations for control which was pretty neat , unfortunately the rise of "standardization" meant most outstations off the shelf and cheap would only run on windows so gradually we swapped over , only recently was i able to relive my youth with riscV OS on a pi which is growing to beyond the walls of the PI i have and i understand a laptop is either coming to or already on the market , encouraging me to wonder if a PC is coming which i would switch to in a heart beat

      @zosxavius 6 років тому +1

      There were many examples of this in the past way back to people adding Z80 cpus to their minicomputers for compatibility and possibly CP/M use. Macs and Amigas had a host of accelerator cards that had PCs built in as well. A lot of these were usually interfaced through an expansion slot so there were of course some downsides. Having foreign CPUs that can plug right into the mainboard in a CPU slot is pretty interesting though yeah. I don't know who else really did that, but I'm sure there are some examples.

    • @huberthans4312

      Its pretty normal for PCs to have additional processors with different architectures running at the same time. Your Networks card or Soundcard maybe has an ARM CPU installed to offload funktions/ prevent buffer underruns. Or PowerPC CPUs on RAID Controllers and so on.

There was even a Symbolics LISP processors in MacIvory cards for a 68k Quadra. Also no simultaneous CPUs in the Amigas' cards and not in the DEC Rainbow: which was an early micro with Z80 for CP/M and 8088 for DOS (not compatible with IBM's DOS). As far as I know, all micros could have only one type of CPU at work at a time.there were some interesting arangemens with video GPUs, even PCs which had two of the same chips, where one was the CPU, and one did video memory only.

    Looking closer at the BSoD you got I think you need a storage driver floppy to boot into NT. What you did get was a missing hard drive. In NT you need to press F1 or F3 during initial boot and supply a driver disk for storage. Then it should boot just fine. I did it a lot when devices like HPT370 IDE raid appeared or much earlier when NT 3.1 didn’t support Matsushita proprietary CD-ROM interface. In that case OS started from 3 disks and then driver floppy to access CD drive.

    3:03 If I remember correctly, Acorn were badly damaged financially by leaks of the systems released immediately before the Risc PC 600, hence the Medusa code name for the Risc PC 600. I worked at one of Acorn's Key Developers in the final stages of the Risc PC 600 development. The Non-Disclosure Agreement for Medusa was considerably longer than my contract with my employer, and the security requirements it imposed were stringent, including not revealing anything about the system to colleagues who had not personally signed the NDA. The pre-release hardware was in an A5000 case, partly because it is what Acorn had to hand and partly because it looked the same as any other A5000 when powered down unless carefully examined. Acorn had a scheme to recase the pre-release Medusas in the final Risc PC 600 casing after the commercial launch of the system.

    There are 32 species of oaks across eastern North America, but squirrels only eat and hoard certain types of ACORNS. Squirrels eat 85 percent of white oak ACORNS shortly after discovery and store about 60 percent of the ACORNS of red oaks.
    Red oak ACORNS contain larger amounts of tannins than the white oak ACORNS. Tannin is a bitter-tasting chemical that works to protect the ACORN from insects and other animals. So rather than eat the red oak ACORNS, they store them.

      Slices are just empty shells to add devices as well as more podules. To add more podules you would also need to upgrade the 2x podule riser card. I have seen 4x risers on ebay. This would handle a 2 slice machine. Podules you can get include SCSI and IDE controllers (the built in IDE controller is really slow), video capture cards, MIDI cards. These machines tended to be used a lot by the BBC and if you remember the kids saturday morning TV shows that had phone in games, well they were running on one of these. Along with all the CGI used in the National Lottery at the time.

    I thought Acorn was over when the other 8-bit models edged it out of the competition but when my friends played on my Electron they were strangely jealous of on account of some of the graphics and whatnot as they were used to ghetto graphics from the Spectrum but the budget specs hindered it but I still played with it until the early 90's.
    I remember seeing the newer Acorn machines and RISC stuck with me all thru the years and I kept reading all the info and maybe Acorn eventually did win in the end and all because of the ARM CPU's in nearly every device in needs of some power these days.

    • @mistie710
      @mistie710 6 років тому +1

      No, Acorn left the 8-bit market behind when the 16-bit market was starting up but couldn't find a processor that they liked. The eventual idea was that Acorn decided to design their own processor based on 32-bit architecture and using the RISC design architecture. The first chip was used in a BBC Micro Second Processor system to design the eventual processor that would power their first ARM systems, the Archimedes range.
      The rest is much as RMC tells it except the story of how Acorn was broken up. The Phoebe/Risc PC 2 was about a week away from being released when the people funding the company at that point led by Stan Boland decided that the Phoebe wasn't up to the task and cancelled it, shutting the workstation division down in the process. It became somewhat obvious in the days that passed that these vultures were only after what they could get out of ARM, splitting up the rest and selling it on, hence all the references to Pace everywhere on the RISC OS system where once Acorn would have been.
      One of Acorns' dealers, Castle, took on the manufacturing of the Risc PC for a few years after that alongside a tarted up version of the A7000 known as the A7000+ and a number of peripheral cards until they finished their own project, the Iyonix. But that's another story!

    British computer manufacturers sometimes go above and beyond and don't make computers, but works of art that act like computers. I'll bet that the ability to use multiple CPUs and even get expansions for the chassis made this _the_ computer to use for servers, government applications, etc. I am just drooling (figuratively) over that computer even though I don't know what I'd do with it.

    Great video, the RiscPC is something I rarely hear about, as it's often overshadowed by its earlier Acorn siblings.
    On the topic of secondary CPUs in a machine, back when the market was full of different architectures, those were common among many different machines to offer cross compatibility. As early as Z80 boards for PETs and Apple II's to run CP/M, Apple II cards with x86 CPUs to offer IBM XT compatibility, to Macintoshes having Apple IIe boards with complete Apple IIe's on a chip for backwards compatibility and of course x86 PC cards like for this RiscPC, x86 PC addon cards were also available on the Amiga with a big variety to choose from, some even offering 16-bit PC/AT compatible ISA slots to use PC hardware and still were a thing in the early 2000's for things like Sun SPARC workstations to offer x86 compatibility by just popping in a PCI card. Amigas even had PowerPC accelerators that made it possible to use the native 68k CPU and the PowerPC CPU at the same time, unlike the Macintosh on which you could only pick to use one at a time.

    • @no1DdC
      @no1DdC 6 років тому +1

      A cache is a small short term memory of the CPU. A split cache just means that the cache is divided between instructions and data. This wasn't the case with earlier CPUs, but has been common for many years now.

    I tried to use one of these things to simulate an antenna using NEC2 back in the 90's. It took over a week to run. The same thing took about 5 hours on an original Pentium computer. That's the difference a built-in maths co-processor makes.

    My dad still has a BBC Model A+, A5000 and his RiscPC, originally a 610 upgraded with a StrongARM card and PC card. He also had an original Archimedes A310 but can't remember what happened to that. I had a SA RPC at uni but sold it at some point :) I did like that the BBC BASIC module sat in the cache of a SA so it ran nearly as fast as it did compiled.

  • @RealRaeddie

    Well resreached video and enjoyable to watch. Some minor additions: Without VRAM, graphic memory was limited to 512K. Also VRAM gave a speed increase as it was dual-ported so the CPU and graphic chip didn't stepped on each others feet.
    The Hydra board never really took up. The multi-processor approach was considered to the to go by Acorn, but then DEC came around with the StrongARM and Acorn was all "Hey, an easy way out" and the Hydra silently withered away.
    Star Fighter 3000 should work on the your machine as it got several compatibility updates and runs natively on current RISC OS machines.
    And yes, there are current RISC OS machines, mostly sold in very small quantities and also the Raspberry Pi. For games compatibility there is ADFFS from the JASPP project which can also be used with a RISC PC. ADFFS sits somewhat on the line between comptibility layer and emulator.
    Aaaaand I better stop rambling now. ;)

    • @RMCRetro
      @RMCRetro  6 років тому +1

      Some nice tips there thanks. I have adffs running on it and mounted lots of disks with some success but starfighter was a no go. I'll check out those patches. I also have some 3.x ROMs and was thinking I may have more success if I get a non strongarm host CPU to try with them and see if that helps. Lots more to try but I'm glad you enjoyed the first exploration of it 👍

    Ahh I love my Risc PC. It has an ARM 600 processor currently but I intend to upgrade that to either a 700 or strongarm. I have also picked up a few other bits including a 586 processor and a 16 bit sound upgrade module. I have to check if I actually need this module after you mentioned the revision 3 board wont need it. I also have an Electron and an Acorn A3020, the educational version of the 3010.
    I typically run Risc OS 5 on my raspberry Pi's too. BBC Basic is still there and has some very good access to the Pi's GPIO pins!

    This is a really fascinating system, it's amazing how much they managed to get into a machine of this age.
    One thing, on these if I recall correctly, only the keyboard is a standard ps/2 socket, the mouse is a weird proprietary acorn connector that looks similar but is incompatible. I think only the A7000 has ps/2 for both ports.
    I remember the joy of replacing the mouse on one of these on a system where I work that unbelievably you this day uses a RISC PC as a controller.

    • @TheUAoB
      @TheUAoB 4 роки тому

      The Risc PC mouse was standard PS/2. The older ARM based Acorns used a quadrature bus mouse, which was arguably superior, but the PS/2 had become "standard" in PCs by this time.
