And the basic schematic of the keyboard can be found here: http://dev-docs.atariforge.org/files/Me ... 9-1987.pdf
page 8 or 9 I think.
I've seen another schematic of the keyboard elsewhere aswell.

I know there are solutions for plugging a PS2 or USB keyboard on the atari, but 'bof', there is a lot of key that does not serve anything.
So I wanted to know what was the communication protocol used by the atari.
If there is someone who has explanatory material, it would help me see if can used an MCU (AVR) to do this.
This is probably a very expensive approach, but I find it more interesting.
I have estimate the price + 200 euro.

joska wrote:Yes, that is a good idea if you want to make an exact replica of the original keyboard. However, then you're still dependent on external (and not very good) solutions if you want to use modern mice. If you reimplement the controller on a modern microcontroller, you can add support for USB mice and joysticks for next to nothing. Or even add USB HID client, so you can use your new keyboard both on your Ataris and on your PC/Mac.
joska wrote:On the contrary, it's of great interest. I'm just suggesting another solution for the controller. Reusing the original controller is a missed opportunity IMO. Unless you plan on creating a mouse replacement as well of course.
Btw I don't suggest to connect a USB keyboard to the ST. I suggest support for USB mice and joysticks in the keyboard.

Completely open. If it works I can easily add to my project.
