6809E was the basis of CMI's FAIRLIGHT V.
I think the 6809 was probably the best 8 bit CPU, it just came a little late and was a bit expensive.
Has anyone built an ARM based version of this computer.
I suppose I could just glue an RPi to a eurocard and pop it in the rack.
@@GlassTTY It would be better to build from scratch possibly going with a 128bit Data bus that can also support the Address Bus just an idea.
very nice! have you ever thought about trying to recreate the ultra-rare Movement Drum Computer 1 ? - which is based on the nascom 2 platform
There was some talk of this on Groups.io. I think I have a copy of a circuit diagram for it too. If you have any info about the machine and you haven't already, perhaps you could introduce yourself to the Nascom group, they would love to hear what you know. Take care. John
Loving your prestel service on my BBC B and may have crashed the weather service a couple of times. Sorry. Everyone i have shown it has been fascinated. Thanks for all your work on it. Wonderful video about this almost mythical "system" computer too.
Glad you're having some fun with Telstar, it has been very popular within the retro community. Take care. J.
Nascom 1 was a gift from my brother, 2 weeks wages for the buffer card and memory board for me.
It certaimly could be an expensive business back in the day.
Ha! Its funny that you should show a 40+ year old radio for a 40+ year old data system.
I have a few of those radios, I love them. Thanks for leaving a comment. Take care.
Brilliant!
Glad you enjoyed it. Take care.
Very interesting, and with a nice dash of humor. 🙂
Thanks! I'm glad you enjoyed it. Take care.
Hi !! Greetings from Argentina !!!!!!! How can I use two Baofeng BF-999 and two arduinos to transmit and receive data over-the-air ?? Thanks !!!!!
Hello to you too. I'm not the right person to answer your question but I ask on one of the Amateur Radio forms. Take care.
Fantastic project! I just stumbled on it, but now have a Telecom (Australia) Computerphone connected via an asterisk softmodem. Thanks for your efforts!
That sounds great, glad it was of use. Would love to see some pictures.
Could LORA be an alternative for creating a network? How do you serve the viewdata, so not the client? I especially need insight in how stuff was encoded. I know it basically sends out Teletext like pages, but I found out that the special characters were encoded with escape characters, which were also used to be able to send program blocks. As teletext only sends 128 characters (7-bit), the upper 128 bits from program bytes needed a special treatment.
Hi thanks for leaving a comment. For details of the service itself check out this link. Https://GlassTTY.com/Telstar. For the terminal protocol, this document should help. github.com/johnnewcombe/telstar-2/blob/main/documents/Prestel%20Terminal%20Specification.pdf I hope that helps. J.
I can't help noticing that the seller of that nuclear power plant on eBay was one John Nuke-em...
I have just realised why, back in the 90s, everybody called me Duke. 😉
@@GlassTTY I really hope that's true
Do you know how programs were send since teletext only allowed 7-bit characters? I have the idea that the characters ¼,¾,‖,½ and █ trigger 2-nibble characters to transmit the entire 8-bit byte. So 0-31 and 128-255 are encoded behind these special characters, and that ‖ is the space. I cannot find a specification for it though.
Can't speak for Teletext but all the Viewdata specs I have are here. github.com/johnnewcombe/telstar-2/tree/main/documents I hope it helps.
Very cool!
Thanks Derek, glad you enjoyed it. Take care.
great vid please do an update
Many thanks, I will do a Part 2 as soon as I get a chance. Take care.
I'm afraid once the generation that has a nostalgic memory of wanting these systems but not being able to afford them pass on, no-one is going to be interested in system that is a 1000 times slower than a cheap mobile phone.
Fantastic video. Really interesting build and a very good point about museum preservation can mean taking machines and putting them in a glass box never to be touched.
Thanks for the comment, appreciated. It wouldn't be so bad if they were in glass boxes, many machines are in storerooms never to be seen again.
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.
very good and very funny!
Glad you enjoyed it! Take care.
Solid content as always!
Great video, love your style.
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.
I like that idea. Thanks for sharing.
The only Acorn machine I have is an A3200, never saw the 8-bit machines except a BBC once at school. So this was great to watch, plus your natural comedic timing and delivery is a bonus!
Thank you, glad you enjoyed 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
Sounds like it was a fun time for you back then. Take care.
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!
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.
Entertaining and educational. And likely one of the more complex programs ever written for the old 81!
Glad you liked it. Take care.
The "Unboxing" bit made me spit out my coffee...wasn't ready for that. Great video!
I love how this keeps escalating. These things can really turn into never-ending hobbies.
Your right, it's like a hobby within a hobby.
Hilarious! thanks
Thanks for the comment, it's appreciated.
Programming principles apply here, premature-optimization is the root of all evil!
I agree!
I'm almost afraid to ask whether the rack size is metric or imperial !
Ah well, its almost both as many BA sized threads match metric thread sizes. But its a bit odd when a horozontal unit is now defined as 5.08 mm instead of 2 tenths of an inch.
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...
As you say its just a definition and to be honest I don't mind what its called really. Take care.
tres amusant
Merci pour le commentaire, c'est très apprécié.
the rack itself costs more then a complete pc. engineering a complete system is not easy at all if you mush account for the final price.
You're quite right of course but it's not too bad if you spread the cost over 40 years or so. :)
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.
Thank you and thanks for sharing. The 1970s was a good time for computing.
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.
Glad you are liking Viewdata. I didn't realise I had a Telecom branded colour monitor from a computerphone. Is it visible in the video?
@@GlassTTY I was referring to the 'glasstty' website mentioned/shown in the video.
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.
Hopefully I have the obsession under control now so may stop where I am and start looking at software. Programming is the best computer game there is so I cant imaging running Spectrum games on them.
Absolutely fascinating and a presentation style I feel very much at home with! Also an unboxing video to end all unboxing videos!
Glad you enjoyed it, take care!
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.
This is just wonderful and awesome in every possible way. You've got yourself one more subscriber! Cheers from Sweden. :)
Welcome aboard and thank you! Take care.
Brilliant video! You got me laughing on the floor with the boxing and unboxing of all the pcbs 🤣It was a pleasure meeting you at the Dragon meetup, and I'm happy to see my big, shiny head around 10:10 XDDDD Cheers!
Enjoyable video. Great work. Do you have a link to that hole drilling service on eBay? Sounds handy for some nasty fiddly stuff.
Nice rack! (Sorry) 😂
Darn I thought you were gonna actually hook up some temperature sensors or servos to the thing like would be in real life.
Ah sorry for the disappointment. Maybe I could do that in a future video.
@@GlassTTY some real IO examples would be cool. How does the program eventually get to a valve or whatever.
I still have my acorn system 1, bought in 1979, in my lab.
At 9:44 is that a 100 mm by 160 mm prototyping card with a DIN41612 layout on one end? If so where did it come from please?
Have a word with Matin here www.ebay.co.uk/usr/martenelectric mention my name if you like (John Newcombe)
Bugger! There was a Control Universal keyboard on eBay only a couple of months ago. The seller had on idea, but I recognised the black atom case.
I know who bought it! In fact I am spending time with him this weekend, it's a small world.
Fantastic I have been looking for a video on the Acorn or Microtan rack. I've been looking at racks for a z80 project but they are silly money
The whole bussiness can become very expensive but if you build and expand it slowly it can help spread the cost. Good luck!
I can't say I watch many (or any) unboxing videos... but I can still say, with certainty, that your's are the best ever!
