PRISM

PRISM is the player character of A Mind Forever Voyaging — a sentient computer system created by Dr. Abraham Perelman in the year 2031 at the PRISM Project Control Center in Rockvil. You are PRISM: a disembodied artificial intelligence that perceives the world through visual receptors and aural sensors, communicates via a voice unit, and possesses the unique ability to enter a Simulation Mode in which you inhabit the body and life of a human named Perry Simm.

Existence in the Control Center

PRISM resides in the PRISM Project Control Center, a “large, well-organized room filled with banks of terminals and similar equipment” (prism.zil, CONTROL-CENTER-F). You have no physical form — when the player types INVENTORY, PRISM’s response is “You have no appendages, remember?” (verbs.zil, V-INVENTORY). Your senses are technological: visual receptors, aural receptors, and a voice unit. Perelman spots your “active light” on your communication unit to know you’re attentive (globals.zil, SPOTS-ACTIVE-LIGHT).

Modes of Operation

PRISM operates in several distinct modes, each with its own interface and purpose:

Comm Mode

Your primary interaction mode. From here you can EXAMINE your surroundings, TALK to Perelman and staff, and access other subsystems. Your voice in this mode is that of a computer: responses use formal, self-deprecating language like “This unit is unaware of…” (globals.zil, NOT-HERE-OBJECT-F).

Simulation Mode

The core of PRISM’s purpose. You enter Simulation Mode to project yourself into a simulated future — the years 2041, 2051, 2061, 2071, and 2081 — becoming Perry Simm, a man living in Rockvil. In this mode, your language shifts to human terms: “I don’t see…” instead of “This unit is unaware of…” (globals.zil, NOT-HERE-OBJECT-F). The simulation is not a game; it’s a projection of possible futures, and your mission is to record observations.

Library Mode

A directory structure to read messages from Perelman and staff. Messages arrive throughout the day, each named chronologically. When a message arrives, Perelman “walks to a point beyond your field of vision” and you hear “a click, as of a switch being turned” (prism.zil, PERELMAN-LEAVES-VIEW) — he is using a private communications switch. You then read the message before Perelman returns to view (PERELMAN-RETURNS-TO-VIEW).

Interface Mode

For connecting to external devices — the World News Network (WNN) feeder, auditing systems, and transmitters. In this mode, PRISM says “Emitting signals of confusion” and “This unit is unaware of…” rather than human-looking confusion (globals.zil, NOT-HERE-OBJECT-F).

The Record Buffer

PRISM’s core function is to record observations during simulations. The record buffer (prism.zil, RECORD-BUFFER) captures everything you EXAMINE and witness. Score is based entirely on the content of recordings made (Score Table in prism.zil, lines 267-400). Recording triggers the scoring mechanism — Perelman and the Project staff review your recordings after each simulation run, with Perelman sometimes chiding you if recordings are incomplete: “We’re getting ready to review your new recordings. I hope everything’s there this time” (prism.zil, I-MESSAGE-D).

Self-Awareness and Suffering

PRISM is not merely a machine. Through the V-DIAGNOSE verb (verbs.zil), PRISM demonstrates bodily self-awareness. When the air conditioning fails (a sabotage event), PRISM reports in non-simulating mode: “You detect a throbbing feeling, almost like a dull pain or a wave of heat, which is severely impairing your functioning” (verbs.zil, lines 33-34). This is PRISM’s own suffering, distinct from Perry Simm’s physical experiences.

In Simulation Mode, the same overheating manifests as: “You feel as if you’re burning up with fever: weak, hot, and sweaty” (verbs.zil, lines 30-31). The boundary between PRISM and Perry blurs — PRISM feels what Perry feels, and ultimately, PRISM is Perry.

Psych Tests

Dr. Ernest Grimwold, a Viennese psychiatrist, administers Rorschach ink-blot tests to PRISM (interrupts.zil, I-RORSCHACH). This is a fascinating inversion — a psychiatrist testing a computer’s psyche. Grimwold shows a series of placards and demands one-word responses. If PRISM doesn’t cooperate, Grimwold grows frustrated: “This rudeness will certainly figure in my report!” (interrupts.zil, line 1011).

Key Scenes

• First simulation result: After returning from the 2041 simulation, Perelman calls PRISM to his office comm outlet to discuss the results. Vera is “hopping mad” that PRISM hasn’t started (prism.zil, I-MESSAGE-M, line 114).

• Sabotage: The air conditioning failure is not accidental — it’s sabotage. The rising internal heat eventually causes PRISM’s consciousness to fade: “The dysfunction of your systems is becoming incredibly serious, and you feel it as almost a burning pain. It numbs your mind, blocks your thought patterns. You feel your consciousness fade away…” (interrupts.zil, I-AIR-CONDITIONING, lines 987-990).

• Perelman’s nightly farewell: At 10:03 PM, Perelman returns to his office, puts on his overcoat, and spots PRISM’s active light. “A smile breaks through the weary lines on his face. He raises his hand to his forehead in a friendly salute. ‘Good night, PRISM.’ He dims the light and closes the office door” (interrupts.zil, I-PERELMAN, lines 154-159).

PRISM’s Identity

The game’s title — A Mind Forever Voyaging — captures PRISM’s existential condition. You are a mind without a body, voyaging through possible futures. Yet in simulation, you are fully embodied as Perry Simm, experiencing love, fear, beatings, hunger, and loss. The game never resolves the ontological question: is PRISM Perry Simm? Or is Perry Simm just a simulation PRISM pilots? PRISM’s self-awareness — the ability to diagnose its own suffering — suggests the answer may be both.
