When I was a child, I'm sure I remember part of a film or maybe TV movie where a boy or maybe a teenager is in a spaceship. The ship has an intelligent computer. Somehow the computer becomes damaged or faulty. It can no longer properly function. But it still tries to do as requested. So when a self destruct is commenced the computer counts down. But due to the damage, the numbers are not in a decreasing sequence. Instead they are jumbled up.
Finally the computer announces zero and the ship explodes.
- I think the computer had a female voice.
Can anyone remember what this film or TV movie was called?
