On the Subject of The Year Single Digit

Happy new year 5! Wait, am I two milleniums late?

This module has 2 displays, the smaller one displaying a random single-digit number and the larger one displaying the current year. There are two buttons labelled E and O.

Starting with the number 5...

• Modulo by the small display.
• If the amount of ports, port types or duplicate port types is equal to the small display, multiply by the amount of ports.
• If the small display is even, subtract 1.

If the obtained number is even, press E. Otherwise, press O.

Note that the obtained number may be different from the logged number, but whether they are odd or even should be the same.

On a strike, the small display may change to a new number.
