I finally threw out my old Astro Wars a couple of years ago. It hadn’t worked in years, as a kid I realised that if you upped the voltage on the power adapter the display went really bright. Higher voltage still and it went really really bright, briefly, and then very dark permanently.
The one photographed / purchased here, there’s a mismatch. The box is for a mark 1, the game itself is a mark 2.
just wait until you complete it at 10,000 points and reveal the majesty of the Victory Tune!
IIRC it’s the same tune as the ‘end of game’ fanfare before it loops back to the first level, only three or four times over.
