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.

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.

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.

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.

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 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

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.

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 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.

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.

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.
