I found a weird keyboard

Also forgot, is "mini-din" a synonym for "ps2"?
Also, there was a larger ps"1"which is on this keyboard I have her in front of me.
It seems, that ps"1" is actually IBM AT/ps2, I have misunderstood, it seems.
I will refer to the smaller male circular connector as minidin now, I previously called it ps2, sorry.

But, if I am quite frank, a split design would be more ergonomic in terms of wrist supination, something like the ergodox.
But then again, this keyboard could make a nice meme-board...
Screw it, I think I'll just do it, might learn a little about micro-controller programming like it was before things like arduino "IDE" programming.

8 Posts in and there is a shitpost. Well done.
I think the user who started talking to me in the beginning is now gone, too. Thanks.

Someone already posted the pinouts for you, dumbass. They clearly show that one pin isn't used. 5-1=4
If you can't figure that out, I think this project is too much for you. Try starting out with a "computers for seniors" type class at your local library.

Thanks for the answer.
Sorry, I didn't see that info on the diagram, is it No3 that drops out?
I don't really know anything about the way usb functions, so I didn't see why 1 for clock in IBM AT becomes 1 for data in the PS2 standard for example.

ps/2 has the little rectangle in the middle
but anything round with pins is usually called mini din

Mine doesn't have a rectangle in the middle, confused what pin-out to map the connectors to now?
Is pic related use-able as a cable? It came from a mouse....

Shows the connector currently on the Keyboard, it looks somewhat like a PS2 variant, however all pin-outs I find that show what the correlating pins on USB-2.0 standard are use a slightly different looking example in the instance of the round connector.

You have a din. Not a minidin. The pinout has already been posted. It should take 2 seconds to translate from din to minidin to USB.

I have an old as fuck keyboard with that. You can get DIN->PS/2 adapters that make it work. No idea if it'll help your particular keyboard but it's a start.

You will likely need to run that through a serial-to-USB IC. From a quick web search, you would take whatever output the keyboard makes, translate it on an MCU to something your OS of choice recognizes, then send that out on USB to your computer.

So an MCU with a UART/SPI interface plus USB will work for your needs. That's what those adapters use. They are molded inside of the rubber case.
