HAL: Look Dave, I can see you're really upset about this. I honestly think you should sit down calmly, take a stress pill and think things over.

Bowman removes the entry door and enters the logic memory center.

HAL: I know I've made some very poor decisions recently, but I can give you my complete assurance that my work will be back to normal.

The computer brain consists of hundreds of transparent perspex rectangles, half-an-inch thick, four inches long and two and a half inches high.

HAL: I still got the greatest enthusiam and confidence in the mission and I want to help you.

Each rectangle contains a center of very fine grid of wires upon which the information is programmed. Bowman begins pulling these memory blocks out.

HAL: Dave . . . stop. . . Stop, will you? . . . Stop, Dave. . . Will you stop, Dave? . . . Stop, Dave. . . I'm afraid. . . I'm afraid, Dave. . . Dave, my mind is going. . . I can feel it. . . I can feel it. . . My mind is going. . . There is no question about it. . . I can feel it. . . I can feel it. . . I can feel it. . . I'm a---fraid. . . .

Bowman works swiftly.

HAL: Good afternoon, gentlemen. I am a HAL 9000 computer, I became operational at the H.A.L. plant in Urbana, Illinois on the 12th of January 1992. My instructor was Mr. Langley and he taught me to sing a song. If you would like to hear it, I can sing it for you.

BOWMAN: Yes, I would like to hear it, Hal. Sing it for me.

Bowman keeps pulling out the memory blocks.

HAL: It's called Daisy. . . "Daisy, Daisy, give me your answer do. I'm half crazy, all for the love of you. It won't be a stylish marriage, I can't afford a . . ."

Hal's voice oscillates to such a low frequency his words are no longer comprehensible . . . then silence.

Suddenly a video activates in the memory center, Heywood Floyd appears on the screen.

FLOYD'S RECORDED BRIEFING.

FLOYD: Good day, gentlemen. This is a pre-recorded briefing, made prior to your departure. Which for security reasons of the highest importance has been known on board during the mission only by your H.A.L. 9000 computer. Now that you are in Jupiter space and the entire crew is revived, it can be told to you. Eighteen months ago, the first evidence of intelligent life off the Earth was discovered. It was buried forty feet below the lunar surface near the crater Tycho. Except for a single very powerful radio emission aimed at Jupiter, the four million year old black monolith has remained completely inert. It's origin and purpose, still a total mystery.
