More like early 90's. In the late 80's it was still common & easy to order schematics, data sheets/books & the like from manufacturers. Usually @ cost, sometimes as a free service.
This was actually the unofficial support policy for Cromemco Inc, "you've got the schematic, what's the problem?".
For example, it's not an accident that software development is a very 'open' industry. You can learn anything about making a NextJS shopping cart online. Because nobody is really getting value by holding this knowledge as secret 'alpha'
On the flipside for example, academics, scientists and journalists often have very different incentives. Getting the credit for being the first to talk about an issue is what matters for their career so they are likely to be guarded about what they're working on or what their methods are
And this is why Zuck open sources LLMs; he is not really selling tokens in some infra service so keeping the output generation scarce doesn't really matter to Meta
(Joel Spolsky had an adjacent idea saying "Smart companies try to commoditize their products’ complements" like Billboard publishes a lot of music journalism for free but monetizes their chats/data)
Anyway, so this explains what's going on with this electronics retailer--while it is still a perspective and effort that is uncommon--publishing the schematic is not competitive with the shop unless you start manufacturing and open up another shop

We didn't have words to describe "Opensource" yet, I wrote (from the above page):
This page is designed to be a home for the Taniwha Flight Computer which
I'm building and kitting for a number of other interested people. This is
NOT a for-profit enterprise - the idea is to get a critical mass of people
up and using the same hardware so that they can write cool and interesting
code (or make cool and interesting hardware) and share it with everyone else
who's using the design.
A quick note about copyrights etc - all the stuff here is marked with my
copyright - this is something I do with everything I design to retain control
of my designs should I decide to sell them for profit in the future. However
everything in these pages, the design itself and the software that runs on it
(at least the stuff I provide) is hereby provided it for anyone's use - but I
retain ownership and copyright (even feel free to build them commercially if
you want).
You can see the gem of what later became GPL/etc there, using copyrights to retain control while releasing it to the world. Later I added: "Open Source" is now all the rage - we've been running this project that way
for the past 4 years - so as always "feel free to steal anything on these web
pages".https://en.wikipedia.org/wiki/Denshi_block
There are professional versions of the Denshi block, used in engineering schools in Japan in the 80's/90's (as I recall), to lay out circuits and serve as a test-bed for student lab work:

In my case, it's just a great reminder of the 70's, and how bright and shiny the future used to seem. Its also a pretty fun little woo-hoo-bonky-boing synth toy, now and then ..
I would have to wonder if there aren't pro blocks in that store somewhere, probably in their own neatly labeled section ..
But then, I'd had a Dick Smith Electronics[1] "breadboard" period, the year before, where the components were literally drilled into flakey particle-boards over the schematic, and .. that was fun too.
I "upgraded" from the Denshi blocks and the breadboards, to a soldering iron station and the Fun-Way PCB's .. burned my fingers on the synthesizer kit .. and the rest is history.

I saw the tail-end of being able to get schematics for consumer devices. I miss that too. Even commercial devices used to be way more open than they are now. Nowadays even farmers have to fight drm to repair their tractors.
Before that, there was science. Although the rules were loosely defined, scientists were expected to provide enough detail in their papers for someone else to replicate their work. That's where I learned about open design, before I learned to program.
Into the modern age, when "code" became part of electronics projects, the magazines printed source code listings, and later required authors to provide their code for an online repository. I published a couple of those articles back in the day.

To me, this was my first really practical example of 'open schematics' - it was like opening a book of deep, dark spells .. which anyone could do.
I enjoy seeing boutique businesses but it's nice to see one where the core operation (not just the IP) has a shot at outlasting the founder.
That’s not how these things work
It's a 100% markup because the selling price is 100% more than the cost.
Some people might call it a 50% markup, but that's purely a deceptive tactic, or just ignorance.
