You have to dig a bit deeper into the TI92 hardware. Turn off all
interrupts (preferebly), set the timer to the same refresh as the
screen, wait for the timer at the beginning of each redraw of the
screen, and read the keys using the keyboard matrix. All of this is
explained in the fargo docs if you read it through.
