PC KEYBOARD WIRING SCHEMATIC | Electronics Forums
control IC from an old keyboard, and wire each keyswitch connection to a momentary button, which is hooked to mechanical levers in the typewriter. Does anyone have a wiring diagram of the internal keyswitches in a standard PC keyboard. I havent been able to fiond one online, all i keep getting is PS/2 pinouts, or the pinouts for the IC. thanks

Computer Keyboard Schematics | Electronics Forum (Circuits
I doubt any PC keyboard is microcontroler-less, even if it's called a keyboard-controller IC, it's certainly going to be a micro. However, I doubt you would be able to buy the pre-programmed micros, far better to simply buy a keyboard and strip it if you need a really strange shape or something.

Look at the schematic on the left. When the switch is not pressed both these presses and it's the safest to wait until they're both released before sending any state changes to the PC. thanks for the warm words and your ideas for the future parts of "How to make a keyboard".
Computer Keyboard Layout – Understanding the Keyboard
Computer Keyboard Normal Keys Layout. So the typical keyboard layout, will look something similar to the one below. If you have an Apple computer then the keyboard will be similar, but won’t include keys such as a Window key or Print Screen key. The keyboard was made for ease of use. The most used keys are generally easier to reach.

PDF filePc Keyboard Schematic Circuit Note: I have many more circuits to add here as time permits. Since I have been asked for a whole-computer schematic of a really basic 6502 computer, An earlier set I did used a full PC keyboard, and it just took a lot of space. This protocol is what almost every PC

Analog Synth Keyboard Schematic
The keyboard bus is held at a voltage of about - 0.4 to -0.5 volts by the 1 meg resistor (R10) and diode (CR1) combination. Whenever a key is pressed the keyboard bus assumes a voltage equal to the number of resistors between the pressed key and ground times 83.3 mV.
