A 'tongue in cheek' look at building an Acorn System Computer 44 years after they were introduced. Enjoy!

Excellent stuff! Looks like a System 3 to me, and I agree 100% about letting computers live on in new hands rather than end up being unused, unloved and forgotten.

Thanks for the video, a real trip down memory lane. I only ever saw pictures of the System computers in magazines. My first computer was an Atom, which I expanded all the way to a disk system. I did build a Richard Russell board at work, which was the Z80 prototype for the BBC Micro. That was before Acorn showed the BBC their Proton, which became the model A/B. I have enough electronics projects on the go, mostly RF related, so I shall steer clear of the vintage computer, modern builds, as it looks highly addictive. Glad you have found a support group though. Good luck. Nick.

Ian McCollum, in one of his videos, brings up very similar points regarding donating collections to museums, allowing collections to be split up, and comparing with selling. Good points all around!
@GlassTTY

It's a tricky one for people with specific collections really and needs a real mind shift. I don't really know the answer but there has to be a better way than now.

Great to see somebody who really knows what they’re doing .Back in 1976 here in Calgary Alberta Canada I went to the first computer Shop in the city called believe it or not The Computer Shop anyways to make a long story short it would cost me about $4000 to build some kind of S 100 kit computer and my older brother talked me out of it but that didn’t dissuade me. I ended up taking a computer science degree and spent probably close to 30 years working with main frames, PCs and other paraphernalia.

Excellent. I've only warmed to Acorn in the last few years (especially after Micro Men movie). I was always a committed Nascom fan (built mine in 1980 at the age of 19). I love Z80 assembler and I've always found 6502 code a little nausea inducing. One of my first jobs was fixing Microtan kits and building Acorn Atom kits (my boss was saving 40/50 quid by buying kits and I could build 2 in a morning and only cost him 30 quid). My Nascom still exists and is partially working but not used since about 1985 when I got my first PC.

I love the Z80 too but overall I favour the 6809, it's amazing. Having said that the 6502 has so few instructions, I can actualy remember them all.

Interesting, and boy are you keen. I followed the glasstty bit and was pleasantly surprised, especially seeing the old Telecom branded colour monitor from a computerphone. I used to work in a repair lab fixing them. I did have one of those screens, but disposed of it long ago, however I still have a few black & white units. I downloaded the Viewdata client terminal software, it worked straight away, now I'm kind of interested in setting up a server..... I will have to try and find the software for my old Tandy TRS-80 model 1, that I used to access the Australian version (well I think I did that), a challenge due to lots of incompatibilities. They were fun days, until Telecom jacked up the prices to the blazes and basically killed it.

I had an Acorn Atom in the 90s, from the local recycling centre. (which was an Aladdin's cave of "retro" stuff back then. We had over 70 computers and consoles from there at one point. It got a bit out-of-hand. lol) Included with the Atom were some DIN 41612 cards built on stripboard. One of them had a Dallas RTC chip on. I think another was for interfacing to an RTTY modem, so likely a HAM enthusiast owned it originally. Sadly, in a bizarre twist of fate, the whole lot got run over by a Land Rover. :( 5:36 - If only it were that easy. lol

What I enjoy about kit computers and early computers like the Apple II is you are active working on your investment. It was a investment since those machine was used for at least a 10 good years or longer. Nobody thought about upgrading the whole entire machine. You just continued to add to it. I wish I could explain it better. Now it just seems so generic to upgrade your machine. For instance if I upgrade my pc right now. I'm looking at ram, processor, motherboard and possible larger psu. Then technically I'm still limited with older video card, monitors, etc. Do I need to upgrade them. No. But that leads me to a brand new system. No magic in it.

I think you're right. The early machines had soul and there was a sadness when you did finally upgrade. It was like saying goodbye to a loved one.

I did not get a proper look at your system 2-3 at retrofest, so it's nice to get a proper look at them now. Looking forward to the follow up videos. You've got a good point about a lot of this stuff just being locked away in storage rooms with nobody using it. If that's where all these machines end up, then there will nolonger be anyone left who knows how to use them, and they just become objects shorn of thier meaning gathering dust.

@@GlassTTY Its a problem we are probably just beginning to see the tip of the ice burg of. As there are plenty of collectors around at the moment with a wide range of systems in fairly regular use. While most of us are fairly healthy and well, and will be around for a while yet, that can't hold true forever. While institutions can out last individuals, if we all leave our collections to museums it just means more machines gathering dust in store rooms.

Hi John. Great to see you back! I know what you mean about the soldering bug - I have far too many serial boards for my homebrew machine 😂. I understand your argument about the authenticity of your machines and was thinking about Trigger's broom before you mentioned it. If it looks like a duck and quacks like a duck... Also, the human body replaces almost all its cells every 7-10 years, so is anyone the same person they were? Still love your quirky style 👍😁♥️

I look forward to the video of where you have a half-rack full of Acorn System 3s + one System 2. Personally I wouldn't stop at genuine non-original cards though. I'd also build some non-genuine original cards for the system, maybe a z80 expansion card that lets you run Spectrum software/games. That said, if I had the money to do all this, I'd probably just opt to build an entirely custom Eurocard based computer running Forth.

What does or doesn't make something original is a bit tricky. It feels like it has to come from the original manufacturer to be original, otherwise it's a clone or replica. What I do know is my lack of room is preventing me figuring out how to build my own. Although I did have a lot of fun building my RC2014...

Getting the rack can be tricky. Verotec still sell them new but at a cost obviously. The rear bars are the thing to watch as you will be looking for something that allows the connectors to be directly mounted to the case. I might include a better explanation in the next video. Why not start the build without a rack for now an see what turns up?

Thanks for the comment, I'm not sure I fully agree, I think there will definitely be a downturn in interest for the reasons you say. But I think that the very early micros from the 1970s and the minicomputers before them will always be of interest. Time will tell I guess. Take care.

13:42 its like the Theseus ship, just keep replacing all parts, now do you have a new ship or its the old one ? I say its the old one because the "form", aka, the abstract interconnection of components is what makes the thing, not exactly the specific atoms that make the actual parts. The soul of the machine is the form and function, not the atoms and parts.
