          if (updatedReceiverControl != 1) {

               System.out.println("EXTERNAL_INTERRUPT_KEYBOARD");
               InterruptController.registerExternalInterrupt(EXTERNAL_INTERRUPT_KEYBOARD);
           }

https://github.com/TheThirdOne/rars/blob/master/src/rars/tools/KeyboardAndDisplaySimulator.java#L774

The problem is this check fails and interrupt is not send ever.

when i created the rar with this check commented

          /*if (updatedReceiverControl != 1) */{

               System.out.println("EXTERNAL_INTERRUPT_KEYBOARD");
               InterruptController.registerExternalInterrupt(EXTERNAL_INTERRUPT_KEYBOARD);
           } 

The interrupt is properly triggered.

Why is this check here ?
my understanding is this updatedReceiverControl is set to one when key is pressed so this check will always fail right ?
