  • so yet again.

  • It's another birthday in the computer world.

  • Another home computers got its 30th birthday, so we have the Mac in 2014.

  • We have the Atari esti in 2000 and 15.

  • We probably moved on the Amiga in 2016 but we didn't on this year.

  • It's the acorn.

  • Arkham.

  • Edie's gonna ask a question this point doctor bag, because this is a British computer.

  • But why would anyone?

  • Well, unless they will know that they probably wouldn't know about the computer directly.

  • They probably know a lot about the processor in it.

  • So a couple of years ago, we did a video on the 30th anniversary of the processor.

  • I think only half the 12 billion arms shipped in the last year went into mobile phones because this was the first computer ever to use the arm CPU.

  • The arm CPI was developed because of this computer, right?

  • It was developed to drive a calls next generation, and this was what they developed.

  • This is what came out of that development yet find one still in its original box.

  • This way.

  • Yeah, absolutely not quite going.

  • It's Sirius cybernetics lift.

  • I did manage to get in the way of things the other day.

  • What Right?

  • We're going this way and we're going to my secret hiding chamber.

  • My secret.

  • A door with a knife, another.

  • Our community is still in its original box.

  • This is one I bought off eBay couple of years ago, but I was fascinated by it.

  • It's actually still in its original box, but this is probably one of the earlier models of it, because when I can release the ah comedians in 87 there were four different versions released.

  • I think one of the never actually left the market, but there was the ES 300.

  • Siri's in the 1/4 100 serious 400.

  • Syria is a professional model and could come with one mega ram or four major ground on the hard disk.

  • You wanted it.

  • The 300 is aimed at the home user, or schools came with 112 kilobytes of RAM or one make of ram.

  • So that's the 305 But there are other machines in the range.

  • The our committees 3 10 is also a BBC micro.

  • When I got this one off eBay, it was advertises a one med machine, but I realized looking at the box on the serial number on the bottom.

  • It originally been a 512 K Machines had then been upgraded at home made 1987 in the UK We won't use this one.

  • We're going to use the one upstairs because it actually works better.

  • This one.

  • I got an early version of the operating system on.

  • We'll go have a chat about what this machine did and why.

  • It was certainly in the UK very, very popular UK.

  • Anyone of a certain age will be very familiar with these because they were bought by pretty much most schools in the UK, so everyone will use them as a kid.

  • The interesting thing about the Arkham Edie's lines, it continued the tradition of being a BBC micro.

  • Certainly they threw 10 in the A.

  • Three or five did so they have the red function keys, which was the staple thing.

  • They were also used by the BBC on screen as well.

  • So lots of TV shows Doctor who another prime time shows.

  • If they knew the computer, he would often be an acorn computer, perhaps rebounds with some fictional brand and so on that appeared on.

  • They're doing whatever it was needed to do.

  • But they're also used behind the scenes, often linked up to external software to generate the graphics, using lots of prime time shows when kids would phone in, play the little on screen game.

  • Yeah, your phone up is a left left, left right giants.

  • So all of those were actually done using committee's computers.

  • We talked about me being on telly, but actually, the thing you have to remember at this when it came out this machine waas incredible For the time of the time it came out, it was a home computer.

  • It's sold for less in £1000 it gave you four minutes four million instructions per second worth of computing power.

  • That's roughly the same amount of computing power that you get in something like probably this sun workstation that we looked at in the previous video.

  • So that some 31 60 which is pretty top of the line for 86 was probably about the same sort of powers you suddenly got in a home computer and actually, that same time Sun introduced their spark super you and we're starting to move to risk based on it is a nice thing about it is a risk machine.

  • When it was originally released, it had an operating system called Offer.

  • Don't ask why no one really knows that, basically was very similar to what was on the BBC Micro, except that it did support Windows myself.

  • So on.

  • So he's got the same sort of user interface.

  • It wasn't really used for a tour on the original release that came with the later version, which was renamed to Risk OS, which you can still get a day in store on your raspberry pi to the operating room still available on dhe.

  • It generally weren't.

  • You have multi tasking cooperative rather than preemptive.

  • So if one pregnant sort of carried away doing something and didn't relieve control to everything else, and you sort of had to wait for it to finish.

  • But it all booted up out of Rome, so they turned on off very, very quickly.

  • You get started within seconds.

  • The risk of two came along about 89 with some of the later versions of the machine, and it continued, you could have graded, so this machine's had the ram upgrade your form bag.

  • It's got an arm three card in its got a corns, local area networking in there and things in the scuzzy card, which gives it It's a nice big artists.

  • It was a really nice machine.

  • First time you could also get a version that ran you, Nick.

  • So acorn ported UNIX do it not Lennox, that I've been really have a proper UNIX to run on this machines.

  • And so you had actually quite a powerful set of machines that were released at that point.

  • Certainly with the Arm three trip, there is powerful as many other UNIX workstations at the time, if not more so course technology March darkness to the produce later version.

  • So you got sort of less interesting looking versions with the A 5000 Alex you to do a few videos years ago.

  • Design of these is quite nice.

  • This one's got to drive.

  • I like it on.

  • Then, of course, you've got later machines, which Sean is very familiar with, which was, of course, the risk PC.

  • This is the sort of the end of the line for the our committees Raging lost, the are comedians badge and looks a bit like a PlayStation two before the PlayStation two.

  • At that point, in fact, all computer started to look like this because that Charlie had a prototype that had this sort of wedge shape effect.

  • But yeah, this is the one that I should let sure and talk about what this one really got used for.

  • Quick, you tell us about these keeps trapping me.

  • It's been the wrong side of the camera for a room in one of my first jobs on day.

  • One of the reasons I got so heavily into computing is I used to help install these kind of machine television stations so used to go around the world installing them places like Moscow, Johannesburg, Seattle, you name it.

  • I've bean there and often put one of these machines in.

  • So this is a version of what the company I work for used to sell on.

  • What we used to live about was they were, to Leslie gets instant, very quickly and easily on dhe.

  • They were pretty much instant on a bit like Steve just mentioned that the OS was in Rome, which meant they didn't have to wait for a hard disk to spin up to load in the operating system.

  • They just kind of turned on worked so right.

  • I forgot how to put it back on.

  • So let's leave it for a minute.

  • Steve Convert.

  • Show you inside and talk about a bit.

  • Well, technically, but we used to use them for on air television automation.

  • So very, very kind of time.

  • Critical application on Do you want it?

  • You needed confidence from the people of protein, so these things fantastic for that.

  • Systems moved three to using Windows and maximal sorts of stuffs instead, but certainly in mid to late nineties, early two thousands and even now some of these are still in operation transmitting television programs.

  • I'm not trucking name any because I haven't worked in the area for awhile.

  • Well, the interesting thing is that you initially notice about this is that when you run an application, a must win the drilling application, which ever kid usedto, is that you get what is effectively equivalent to the doc that's in sex or the start menu that is in the windows from $95.

  • So the focal goes is that someone went from working with a cool machines like this to Microsoft and took his acorn with him and apparently was seen.

  • And they decided that's where the Windows 95 start menu was going to come from.

  • Some of our quest, whether I believe that or not.

  • But that's certainly how the focal go.

  • So you end up with the icons down here, and you could then so any often it's only by risk or three came with the applications built in to Rome, and so you could load them up very, very quickly and so you could start to draw pretty pictures you had busy explains in there again, from 1987 this is the original welcome to send.

  • Perhaps the thing that the arm arteries were first released was most famous for Waas.

  • A demonstration of game that was on the actual welcome disk and is actually released is a full game so heavy that so this is what happens when you try and run 1987 software on a machine operated from 1993 even though it was out of date.

  • So let's find a slightly later version of the welcome disc cuz of the drive.

  • That's just showing off to for absolutely.

  • And that this doesn't work.

  • Um, summer, I've got you under the coffee of application.

  • Just the copy of application.

  • Just warned there a backup copy.

  • So sometimes he fall.

  • Please would dies.

  • He often would make backup copies.

  • Uh, let's try this one.

  • It sounds more helpful.

  • And so there was this game called Lander, which became a full games arch.

  • I'm when this game was released, it was sort of full three D graphics, which was not really seen like this.

  • And the idea was you had to sort of fly the spaceship around the city.

  • Just a demonstration, and I was never any good at it.

  • I remember being blown away by this.

  • Yeah, I think everyone wants when it came out and this was the sort of the demo again, You've got the 87 thing there written by David Robin off elite fame who they might want to be involved with the creation of the Raspberry pi.

  • This originally came out when everyone said no.

  • You couldn't do this on anything, Butch.

  • The acres are committed because you need the power.

  • It was late reported the gang virus to the S t on the Amiga.

  • And then, in a true bizarre turn of fate, someone actually portage oven anesthetic spectrum on a bit machine with the four megahertz processes.

  • So perhaps they were everything, but certainly the conversion on the our committees wants the smoothest.

  • The contrast is it was controlled by the Mass, and it's incredibly sensitive.

  • So even on the launch pad, if you're not careful, you can blow things that when you consort of explore, because he was an interesting sort of clipping issues, there is the house or fall through the land Escape is that you know that there's definitely claims with about, I'm sure if you look in the right places, you could find copies of the disks and an arm emulator on our committee is emulated to run it on.

  • Yes, it's a bit like the Old Moon Lander game used to get no came over.

so yet again.
