If the reciver program was missing code to store the data, that probably means this is the first time the transmitted program has been seen since the transmission 😄

[@_nc513_]

The C64 receiver prog printed in the magazine was indeed missing a few crucial ML instructions, but as I explained on lemon64, I noticed the audio track they transmitted in an earlier episode of '4 computer buffs' actually did include the complete receiver code. So if someone back then recorded that audio to a cassette tape and managed to load it back on a C64, then they might've gotten this to work.

Nice episodes. And speeding tickets in the US aren’t speedy. The officer in Louisiana took 45 minutes to write me up - he said it was because of the Dutch drivers license. And that was 2008 and I still haven’t gotten that ticket, or did the rental company gave me a surcharge. I think Officer Brown (that was his name) had enjoyed our banter that he never registered the ticket. We both laughed a lot. But the speed limit was 70 and I did 82… So he was right to fine me, although according to him it was safe: “the only thing I could hit was a stray alligator”.

[@jimboAndersenReviews]

Several things to comes to mind: This Thames taped broadcast could be used for giving students an example of how to salvage data. One could manually go through the taped broadcast and write the data stream by hand, or attempt to build a device like it was intended. What sort of students, one may ask? Uh, evening classes in cryptography at a local community center, definitely, so anyone who has the time and the interest. Also, this episode gives a much more realistic depiction of a "hacker"; not some guy in a hoodie, wearing leather gloves and sunglasses, but dressed just like the rest in that neighborhood :3

[@elijahvincent985]

This video is key testament as to why you should not only still have CRT TVs, but also have proper video to digital transfers!!! This dude ROCKS for going the extra mile!

[@VonOzbourne]

The other side being that if you want to play a light gun game ever again, you need that frame rate and interlacing for it to work properly.

[@nzvhs]

Absolutely! It's frustrating how many analog video converters just throw away half the information. It's additionally tricky with KZbin as you need to upscale to 720p for it to preserve the deinterlaced 50fps and full PAL resolution. Modern codecs also don't handle SD resolution with analog noise well, so it's tricky to get right.

[@BigOlSmellyFlashlight]

exactly, i collect tapes just so i can transfer them in 60 fields and archive the contents because nobody else wants to

[@RonLaws]

I think the next natural step is to go Full Mythbusters on this. The original criteria did not work, We've proved there is data in the flashes, Now to see what it takes to actually pull it off! (Improved circuit and re-encoded flashes with the fixed code)

[@SimonBauer7]

the flashes werent broken, the cirquit and Receiver program was, so you need a different cirquit, heck Just slap an mcu on there, change the phyton code to c, then make a serial Receiver program and done.

[@RetroRecipes]

@@SimonBauer7 How would the Marvel Cinematic Universe help us here? Seriously though, I'm intrigued in building a receiver that would work. If you think you could collab on that feel free to fax or email me [e-mail] +1 747 PERIFAX 👍🕹

[@0LoneTech]

Fascinating thing, the circuit was readily commercially available! It's a light pen!

[@Nicoya]

@@RetroRecipes The circuit as shown is basically just stretching the light pulses from the phototransistor into a more regularized sequence of pulses that the computer will have an easier time reading. Being able to successfully decode the pulse train would require having zero drift between the pulses coming in from the circuit and the code running on the computer, and that probably would have been achieved by sneakily using the power mains frequency as a shared clock for the original transmission. But in your setup you almost certainly do not have that synchronization between your laptop playing back the video and the computer trying to read it, and so the two would drift out of sync probably fairly quickly unless you were very, very lucky. In order to decode this successfully you'll either need to genlock the playback signal, likely using the computer's video-out as the master, or build a slightly more sophisticated receiver circuit that extracts both a field-clock (probably using a phase-lock loop) and the data pulse train, plus a more sophisticated receiver program that would be able to adjust its timing according to the reconstructed field-clock. You'd probably want to do it by reading the clock bit in a tight loop and waiting for it to transition and using that as the cue for reading the data bit.

[@theweekthatis]

@@Nicoya I agree, the frequency will be drifting all over the place.

[@Cylon_Centurion]

In 1983, the Finnish Broadcasting Company broadcasted C64 programs in a radio show called Kansanmikrokerho (The People’s Microcomputer Club). I recorded them on a cassette tape, and they worked just fine. In 1985, a commercial local radio station in City of Tampere, Radio 957, also broadcasted C64 programs. The broadcast was implemented in such a way that one of the stereo channels transmitted the C64 data stream, while the other transmitted music.

I have never, ever, in the history of the interwebs, felt the creator's pain so much. I am literally emotional at the end of this journey..

[@RetroRecipes]

🤗

[@Rezmason]

Yes! And, creator pain is so underrepresented! Swept under the rug. It's good to witness the struggle, to relate to it, to see that folks everywhere are giving something their best shot, not knowing if they'll even conclusively succeed or fail. This story would have felt so different without all those tough moments.

[@chillzwinter]

They should have written the original code to allow you to see the 1's and 0's rolling in across the screen in real time. This would have given the user some feedback that a stream of values is being received, and would allow them to tweak the potentiometer to allow them to see how the received binary was looking. I could imagine as a kid reading the first 100 bits with different pot settings to ensure i was getting a constant set of binary. They could have even started the sequence with 100 alternating 1's and 0's as a test header. Such a program could still be created today as a "test program for decoding on screen flashes". After recieving the ones and zeros there should be a menu that says 1) convert to HEX or 2) Convert to ASCII BASIC or 3) Save and Run

[@chaos.corner]

This is why the ZX81 and Spectrum had loading stripes. (for tape loading).

[@markmowbray1769]

Tech has moved on, it’s not cheating its modern day archeological study in to what was once, simply amazing tech. Well done.

[@electronraygun6346]

Having seen the 4 Computer Buffs programs on KZbin I had considered trying to build the decoder and give it a go but I was put off when I considered the low quality of the uploaded videos. In a way I'm relieved I didn't as I probably wouldn't have realised the code wasn't complete. There's a fine line between having fun with a project and getting nowhere sometimes. You need to make enough progress to keep you interested or it just feels like an exercise in frustration. I also wondered if making the dot full screen might help! So it was kinda cool to see how that would have turned out. But most of all, it was amazing to finally see what wonders had been hidden behind that little flashing dot after all these years! Well done! 🎉🎉🎉🎉🎉

That is an incredible bit of digital archaeology you have performed, sir! The most impressive part of the whole thing is you being able to acquire a copy of the original broadcast in high quality, and at that point I likely would've done the rest programmatically myself rather than try to continue with the physical circuit.

Brilliant work, well done, and a couple of genuine LOLs in there! You're probably one of the only people - maybe the only one - to have got this code running. I'm sure the pipeline from video player to screen was an issue and the only way you could have maybe got it to work as intended is to play an actual analogue tape recording direct to an analogue display. But I've no idea how you'd get their archive file onto tape without affecting it in some way, so you really did come up with the only solution.

But I’ve seen this experiment somewhere else, and I recall thinking, ‘Huh, I wish I had a computer.’ We had one kid in our school who had a Commodore PC, and I hung out with him as a little kid because he was the only kid in the school with a computer. My parents eventually got a TANDY 1000, but that was lame because they didn’t let me do anything but play Oregon Trail… and there’s only so many times I can handle dying of dysentery, whatever that was… lol. I’m gonna try to look at my old journal to figure out who else did that stupid dot on the TV project. I swear I've seen it Somewhere else. I was born in ‘77, so we’re not that far apart. But watching your video, I see my ‘80s nerdy self in you. I just want to give you a BIG HUG for hanging in there and making it happen.

There was a C64 program we used to use on Amateur Radio called "Buddy Term", with the help of an MFJ-1224 RTTY Interface we could download programs over radio at 1100 baud. 1100 is a non-standard rate, but we used this because it worked reliably over the 2 meter radio band. 1200 on 2 meter band on a C64 just didn't work, so we used a non-standard baud rate. It worked quite well, it had error detection and resending bad data. This kind of reminds me of those days. The program also had a chat mode and press F8 it would query a list of stations in range.
