Look at the hardware
I tink this might run most of Krake firmware
Most Missing is the five LEDs
The MUTE could be on screen.
The rotary encoder could be obsoleted with a touch interface.
External five LEDS (or more) could be implemented on an I2C bus if we were to design a PWA.
Same for a DB9 COM port, and external PWA.
Same for a phyical Mute button.
