Poole said, "Exactly."

"Do you know why you never guessed? There must have been signs… clickings and whirrings from inside you, now and then. You never guessed because you were programmed not to notice. You'll now have the same difficulty finding out why you were built and for whom you've been operating."

"A slave," Poole said. "A mechanical slave."

"You've had fun."

"I've lived a good life," Poole said. "I've worked hard."

He paid the facility its forty frogs, flexed his new fingers, tested them out by picking up various objects such as coins, then departed. Ten minutes later he was aboard a public carrier, on his way home. It had been quite a day.

At home, in his one-room apartment, he poured himself a shot of Jack Daniel's Purple Label – sixty years old – and sat sipping it, meanwhile gazing through his sole window at the building on the opposite side of the street. Shall I go to the office? he asked himself. If so, why? If not, why? Choose one. Christ, he thought, it undermines you, knowing this. I'm a freak, he realized. An inanimate object mimicking an animate one. But – he felt alive. Yet… he felt differently, now. About himself. Hence about everyone, especially Danceman and Sarah, everyone at Tri-Plan.

I think I'll kill myself, he said to himself. But I'm probably programmed not to do that; it would be a costly waste which my owner would have to absorb. And he wouldn't want to.

Programmed. In me somewhere, he thought, there is a matrix fitted in place, a grid screen that cuts me off from certain thoughts, certain actions. And forces me into others. I am not free. I never was, but now I know it; that makes it different.

Turning his window to opaque, he snapped on the overhead light, carefully set about removing his clothing, piece by piece. He had watched carefully as the technicians at the repair facility had attached his new hand: he had a rather clear idea, now, of how his body had been assembled. Two major panels, one in each thigh; the technicians had removed the panels to check the circuit complexes beneath. If I'm programmed, he decided, the matrix probably can be found there.

The maze of circuitry baffled him. I need help, he said to himself. Let's see… what's the fone code for the class BBB computer we hire at the office?

He picked up the fone, dialed the computer at its permanent location in Boise, Idaho.

"Use of this computer is prorated at a five frogs per minute basis," a mechanical voice from the fone said. "Please hold your mastercreditchargeplate before the screen."

He did so.

"At the sound of the buzzer you will be connected with the computer," the voice continued. "Please query it as rapidly as possible, taking into account the fact that its answer will be given in terms of a microsecond, while your query will -" He turned the sound down, then. But quickly turned it up as the blank audio input of the computer appeared on the screen. At this moment the computer had become a giant ear, listening to him – as well as fifty thousand other queriers throughout Terra.

"Scan me visually," he instructed the computer. "And tell me where I will find the programming mechanism which controls my thoughts and behavior." He waited. On the fone's screen a great active eye, multi-lensed, peered at him; he displayed himself for it, there in his one-room apartment.

The computer said, "Remove your chest panel. Apply pressure at your breastbone and then ease outward."

He did so. A section of his chest came off; dizzily, he set it down on the floor.

"I can distinguish control modules," the computer said, "but I can't tell which -" It paused as its eye roved about on the fone screen. "I distinguish a roll of punched tape mounted above your heart mechanism. Do you see it?" Poole craned his neck, peered. He saw it, too. "I will have to sign off," the computer said. "After I have examined the data available to me I will contact you and give you an answer. Good day." The screen died out.

I'll yank the tape out of me, Poole said to himself. Tiny… no larger than two spools of thread, with a scanner mounted between the delivery drum and the take-up drum. He could not see any sign of motion; the spools seemed inert. They must cut in as override, he reflected, when specific situations occur. Override to my encephalic processes. And they've been doing it all my life.

He reached down, touched the delivery drum. All I have to do is tear this out, he thought, and -

The fone screen relit. "Mastercreditchargeplate number 3-BNX-882-HQR446-T," the computer's voice came. "This is BBB-307DR recontacting you in response to your query of sixteen seconds lapse, November 4, 1992. The punched tape roll above your heart mechanism is not a programming turret but is in fact a reality-supply construct. All sense stimuli received by your central neurological system emanate from that unit and tampering with it would be risky if not terminal." It added, "You appear to have no programming circuit. Query answered. Good day." It flicked off.

Poole, standing naked before the fone screen, touched the tape drum once again, with calculated, enormous caution. I see, he thought wildly. Or do I see? This unit -

If I cut the tape, he realized, my world will disappear. Reality will continue for others, but not for me. Because my reality, my universe, is coming to me from this minuscule unit. Fed into the scanner and then into my central nervous system as it snailishly unwinds.

It has been unwinding for years, he decided.

Getting his clothes, he redressed, seated himself in his big armchair – a luxury imported into his apartment from Tri-Plan's main offices – and lit a tobacco cigarette. His hands shook as he laid down his initialed lighter; leaning back, he blew smoke before himself, creating a nimbus of gray.

I have to go slowly, he said to himself. What am I trying to do? Bypass my programming? But the computer found no programming circuit. Do I want to interfere with the reality tape? And if so, why?

Because, he thought, if I control that, I control reality. At least so far as I'm concerned. My subjective reality… but that's all there is. Objective reality is a synthetic construct, dealing with a hypothetical universalization of a multitude of subjective realities.

My universe is lying within my fingers, he realized. If I can just figure out how the damn thing works. All I set out to do originally was to search for and locate my programming circuit so I could gain true homeostatic functioning: control of myself. But with this -

With this he did not merely gain control of himself; he gained control over everything.

And this sets me apart from every human who ever lived and died, he thought somberly.

Going over to the fone he dialed his office. When he had Danceman on the screen he said briskly, "I want you to send a complete set of microtools and enlarging screen over to my apartment. I have some microcircuitry to work on." Then he broke the connection, not wanting to discuss it.

A half hour later a knock sounded on his door. When he opened up he found himself facing one of the shop foremen, loaded down with microtools of every sort. "You didn't say exactly what you wanted," the foreman said, entering the apartment. "So Mr. Danceman had me bring everything."

"And the enlarging-lens system?"

"In the truck, up on the roof."

Maybe what I want to do, Poole thought, is die. He lit a cigarette, stood smoking and waiting as the shop foreman lugged the heavy enlarging screen, with its power-supply and control panel, into the apartment. This is suicide, what I'm doing here. He shuddered.

"Anything wrong, Mr. Poole?" the shop foreman said as he rose to his feet, relieved of the burden of the enlarging-lens system. "You must still be rickety on your pins from your accident."
