Reading Panel Setting Status
The operator's commands input through the control panel are all sent to the keyboard
interface chip U59 via U66. It also collects the frequency data from the AMP board and
setting of DIP switch. These status and data are acknowledged by the MAIN CPU to be
processed following the operator's settings. Namely the operator selects the presentation
mode of upward and downward combinations; for example, the MAIN CPU generates and
sends the control command to the gate array to display the designated mode.
