Any programmers familiar with Reactor?

I may have just stumbled upon an easter egg but I'm new to this game and have no idea.

Notice the CH at the top where there would normally be a square. Anyone have any idea what I did to trigger that?

BTW rolling the score (in the released version that allows it) would deactivate the easter egg...unless you again pass the 200k mark.

I almost titled this thread, "Hey! Nukey Shay! Can you help me with this?" :)

 

You rock. Thanks for the breakdown. Now I don't have to sit and experiment with it.

No theory at all. I believe that there is some uncertainty due to that first check. Ram location $A1 contains various flags that are set during a game in progress. If any residual flags were not cleared somehow, the easter egg will not be shown. I suppose that more investigation is required to find out if these circumstances appear in a game. But yeah, the act of passing 200k will cause the next test to fail - displaying the initials.
