It works randomly here… you just have to be lucky.

One could use https://archive.org/ here. I think it would be great if this way a lot of old internet pages / circuits could be saved this way! But it is still a lot of work to do the categorization and curation of these links!

I would like to add my GitHub repository that contains schematics and PCBs related to my polysynth, some Kosmo modules and other sdiy stuff.

The Pinouts Book was created for designers and engineers
as a quick reference for remembering the functions of all the
different pinouts in your electronics projects.
The book covers a range of commonly used components,
such as connectors, single board computers, dev boards,
microcontroller chips, modules and more.
More technical information for each component is available by
going to the “pinouts.org/XXX” URLs at the top of the pages.
These each redirect to official datasheets or specifications.
For more info, visit pinouts.org
Happy building
NODE & Baptiste

And another one: pinouts.ru
We are gathering and investigating information about interfaces of modern and obsolete electronic hardware: pinouts of interface ports, layouts of expansion slots, information about other connectors of computers and various electronic devices. Information on functions of pins in connector (pinout) is essential for everyone who want to investigate modern computer hardware, explore the way it’s works, connect various devices to computer, make DIY electronic devices.

These aren’t schematics, per-se, but maybe useful references.
(Since if this content is old, but still relevant)
(E&MM is available at the World Radio History link above, I believe)
I’ve also got PDFs of Bernie Hutchins’ excellent Musical Engineer’s Handbook, and the collected back issues of Electronotes. I can’t find the link to the site where I downloaded them, but I’m happy to share. I’m not sure about the legality of hosting the files on Github, since Hutchins was still selling the material up until a few years ago (around when COVID started). I don’t know if he still is.

I would be exceedingly excited to have access to Bernie’s documents. Please keep me in mind if you find a way to share.

Utterly shameless!
Your code is nowhere near as messy as mine is after I’ve annomized the original from your git hub. Keep going and thanks for sharing!
