Any thoughts on adding support for AT/PS2 keyboards? #34

I have some cool retro keyboards that I'd like to use with a terminal. Any opinions on adding PS2 support to picoterm?

Hi Proper, We are planning to use the I2C bus on the expansion port (see issue #21). The code is ready... I'm currently putting my RC2014 into a case (raison for some delay).

Thanks to I2C bus, we could use a "PS2 Keyboard Mouse I2C module". It should not be too difficult to support it.

We could also create an "PS/2 to I2C" converter with a Super Cheap Raspberry-Pi Pico :-)

It also exists the SK5221 I2C encoder for Keyboard Matrix (used when you want to create your own keyboard).

Interesting... Thanks!

After some additional reseach I did located several products converting "PS/2 Keyboard + PS/2 Mouse to USB". So we can possibly use the Pico USB input with an PS/2 keyboard. Just needs to test it.
