Korg: Tekt NTS-2 Oscilloscope Kit

Regardless - once this one comes out, I'd consider getting one, maybe on the second hand market. If you want an oscilloscope for audio purposes and are on a budget, you can go much cheaper - any of those $20 oscilloscopes on amazon will let you measure audio signals fine, although the displays are lower-resolution than I'd like for this purpose (and I'm not sure this one is much better in that respect). Conversely, for $200 you can get oscilloscopes with much better specs , many of them arguably overkill for audio purposes. That said, this one definitely has some attractive features for audio, specifically the form factor and I/O make it pretty convenient to just plug in (and pass through) a stereo signal without much fuss.
To hook up your 1/4" signal, add a splitter to your output, and use one side to drive whatever you're outputting to, and the other side to measure the signal on the oscilloscope. Ready made 1/4" to BNC adapters are available, so you don't even have to use oscilloscope probes
2200 series and 2400 series are probably the sweet spot in terms capability for money, weight, reliability and repairability. I particularly like the 2245 and 2445, which have basic (digital) measurement capabilities and digitally controlled attenuators. 2225 and 2215 are also solid options. I would stay away from the analog/digital hybrid and digital scopes from this series (243x, 2440, 2210, 2212, etc).
T900 series scopes are good too, but have somewhat lower specs.
400 series scopes are just as capable as the 2200/2400, but much heavier, older and more likely to need re-capping. Some 400 series also have a not-very-good built in DMM.
For audio work, you could also check out the 5000 series mainframe scopes, but that inevitably leads down the rabbit hole of wanting all the plugins (and there are many neat plugins!)
There are also a ton of new $200-class digital scopes from china.
Anyway here is Loopop's review of the NTS-2: https://www.youtube.com/watch?v=A_LtC6HI5YI
and his review of the NTS-1 which is IMHO a better choice if you want a fun musical toy: https://www.youtube.com/watch?v=Vhonu-rM0B0
As an educational tool, the limited functionality makes it more focused than a generic oscilloscope and in a tighter form factor. Pairing the book with the hardware will make the experience smoother than a broader guide like "Welsh's Synthesizer Cookbook".
This isn't for everyone, but should be appealing to collectors or knob tweakers looking to learn this domain. It will most likely retain its value or appreciate over time, as well.
It's a DIY-ish kit with a low-cost BOM, no doubt about it. The limited availability / exclusivity is why it costs more than the $20 hobby kits on Amazon.

Disclaimer: currently waiting for DATA.
I went for a 4 channel Rigol instead of the Mordax as I thought the extra capabilities were worth the small price increase
* I have other modules for envelope generation
* I tend to use a scope when prototyping hardware/software
* the DSO is on the desk, much closer to the stuff being tested than the rack isAt that price point, there are A LOT of options, I'd recommend one of those 10MHz handheld oscilloscopes.
but I think that the more apropos comparison would be the mordax data: https://www.mordax.net/products/data
But Korg makes good stuff.
Under $10. Search for "DSO138".
Then again, I've mostly been looking at vector network analyzers lately so ~$200 for electronic test equipment for professional use seems laughably cheap to me.

The article does mention that 'In the early years of television, the ABC had been using Lissajous curves as fillers between programmes.'
I found this Youtube video [1] from the mid 80s as an example. The comments say (auto-translated):
"There was a big report in the Elrad 06/1997 about the advertising separators and an interview with the man who produced them. Filmed from an oscilloscope, copied to positive film, coloured and mixed with other figures. Everything was produced analogue, partly with bicycle dynamos and tape heads with a circular saw blade between the magnet and the pick-up, quite interesting to read what kind of effort was put into it..."
And off-topic but funny if true:
"By the way, the blondie in the Duplo ad is Jason Connery, Sean's son. He probably also played Robin Hood in the English series at about the same time."

EDIT: One of the nation wide stations had cartoons, the other I don't remember.
Iirc there was a similar product, or was there only the scope?
