Display card A2
The display card communicates with the CPU card through a serial
3
interface. The CPU card informs what should be displayed in the
display window and the display card converts these messages to
information that controls the alphanumeric display window.
The display card also detects which buttons are pressed on the con-
trol panel and sends these signals to the CPU card.
