The Floppy Disk That Tried to Die: William Gibson’s Agrippa

Before Johnny Mnemonic asked for room service, there was Agrippa.

For Halloween, we investigate a digital ghost story from 1992—a poem that was supposed to disappear forever after you read it.

There are plenty of ways for a video game to disappear. A cartridge can break. A disc can rot. A publisher can close its servers, taking a game’s multiplayer modes—and sometimes the entire experience—with them. And sometimes, the people who made a digital work want it to disappear.

That last possibility sounds like something from a horror story. In 1992, it became a piece of experimental art.

Its name was Agrippa (A Book of the Dead), and its creator was William Gibson, the science-fiction author whose novel Neuromancer helped define cyberpunk. Working with artist Dennis Ashbaugh and publisher Kevin Begos Jr., Gibson helped create an unusual book that combined visual art, poetry, and a computer program with a very peculiar trick: it was designed to show its poem once, then make that experience difficult to repeat.

This was not a haunted cartridge. There was no cursed Nintendo Entertainment System hiding in an abandoned house. Instead, the horror came from something much more familiar to anyone who has ever watched a favorite game disappear from a digital storefront.

What happens when the thing you want to experience is designed not to last?

A Book With a Built-In Expiration Date

Agrippa was an artist’s book, not a novel you could pick up at the local bookstore. Its physical pages featured artwork intended to fade when exposed to light, while a floppy disk concealed within the book contained Gibson’s electronic poem.

When the program ran on a period Macintosh computer, the poem scrolled up the screen. The experience was deliberately difficult to stop and revisit. When the text finished, the program presented an encryption-like effect that appeared to scramble the poem beyond recovery.

The program also modified its own files, corrupting part of the code required to run it again.

Think about that for a moment. In an era when computers were still relatively new to many households, someone had created a literary work that treated digital media not as a permanent container for words, but as a temporary event. You did not simply own the poem. You experienced it—and then it was supposed to be gone.

The title itself evokes death and remembrance. The poem reflects on memory, photographs, family history, and the way the past slips away from us. Its vanishing act was not just a technical gimmick. It was part of the artwork’s meaning.

And, naturally, people wanted to know whether it really worked.

The Mystery of the Self-Destructing Disk

Stories about Agrippa have sometimes made it sound as though the floppy disk magically erased every trace of the poem after one reading. The truth is more interesting.

The program’s apparent re-encryption was largely theatrical. Research into the software showed that it displayed a scrambled version of the text as an effect, rather than securely encrypting the poem anew and saving that encrypted version back to the disk. The original text remained recoverable through technical analysis.

The self-destruction, however, was real in a more limited sense: the program overwrote part of its own stored routines, making the original software unable to run normally a second time.

In other words, Agrippa did not possess supernatural powers. It used code to create the appearance of an irreversible disappearance, while making a genuine effort to frustrate repeat access.

And the poem did not stay secret for long. Its public debut in December 1992 was recorded, and the text circulated online almost immediately. The very technology that was supposed to make the work fleeting also gave it a way to survive beyond its original physical form.

The digital ghost had escaped its container.

You Can't Put the Internet Back in the Floppy Disk

Here is where Agrippa becomes especially relevant to anyone who cares about video game preservation.

The work was intended to be experienced in a particular way: a physical book, a floppy disk, an old Macintosh, and a program that would perform its disappearing act. A transcription of the poem preserves its words, but not the entire experience. A video of the program preserves its appearance, but not the same interaction. A recovered disk image preserves information about the software, but it still needs appropriate tools and technical knowledge to make the experience accessible.

These are different kinds of preservation, and none is a perfect substitute for the others.

The same problem confronts video games every day. A copy of a game’s dialogue is not the game. A collection of screenshots does not preserve its controls, timing, sound, or surprises. Even a working copy may lose something if the hardware, accessories, online services, or surrounding context are gone.

A game is something you do, not merely something you read about.

Researchers at the University of California, Santa Barbara, and other institutions have documented Agrippa’s history, recovered its software, and made an emulated version available for study. The project demonstrates that preservation can mean more than keeping an object in a display case. Sometimes it means understanding the code, documenting how it works, and finding a way for future generations to experience it.

You can explore that work through The Agrippa Files, an archival project devoted to the book, poem, software, and the mystery surrounding them.

The Scariest Part Is That It Almost Worked

There is something unsettling about a piece of media that refuses to be revisited.

We tend to think of digital information as permanent. Copying a file is easy. Backing up a hard drive is routine. The internet remembers things we would often prefer it didn't.

But digital permanence is an illusion. Files become unreadable. Storage devices fail. Passwords disappear. Companies shut down services. Formats become obsolete. Copyright restrictions can prevent people from preserving or sharing a work even when the original publisher no longer supports it.

And sometimes, a creator deliberately builds disappearance into the experience.

Agrippa forces us to confront a question that applies just as much to a beloved game as it does to experimental poetry: if a work is meant to be experienced only once, does preserving it betray the creator's intention—or preserve that intention for people who never had the chance to experience it?

There is no simple answer. The experience of encountering Agrippa in 1992 was different from watching an emulation decades later. But without the work of archivists and researchers, we might know its legend without being able to investigate the reality.

A preservation project cannot turn back time. It can, however, keep the evidence alive.

A Ghost Worth Keeping

We usually think of preservation as rescuing something from an accidental death: a forgotten game, a failed console, an abandoned server, or a box of cartridges destined for the landfill.

Agrippa offers a stranger case. Its disappearance was part of the plan. Its fragility was part of the art. Yet the work's story is now inseparable from the attempts to recover, analyze, and preserve it.

That is why this is such a fitting Halloween story for The Mystery Cartridge. The scariest thing in the machine was never a demon, a virus, or a supernatural force. It was the possibility that an experience could vanish—and that, once it did, we might never know exactly what we had lost.

Fortunately, someone kept looking.

And in the digital world, sometimes that is the difference between a ghost story and a history book.

The Mystery Cartridge verdict: Open the file — Recommended.

Not because Agrippa is a video game—it isn't, in the usual sense—but because its story illuminates a problem that every gamer, collector, developer, and preservationist should care about. Digital works are not immortal simply because they are made of data. Sometimes they need someone to save them.

This Halloween, we're glad someone saved the ghost.
