The Poem Running in Emulation

William Gibson’s poem played from a 3½-inch diskette on a 1992-era Mac computer running the System 7 operating system. When the diskette ran, the text of the poem scrolled up the screen (accompanied by infrequent sound effects: a camera shutter click, a gun going off) while an encryption program on the diskette encoded each line and made the poem “disappear” after its first reading.
      On December 9, 2008—the sixteenth anniversary of the original “Transmission” event debuting AgrippaThe Agrippa Files was aided by the Maryland Institute for Technology in the Humanities and the Digital Forensics Lab at University of Maryland, College Park, in unveiling an emulated run of the poem based on a bit-level copy of an original diskette loaned by collector Allan Chasanoff. The copy was played on a computer with software emulating the functions of a 1992-era Mac. For a discussion of the forensic process by which the code was accessed and emulated, see Matthew G. Kirschenbaum, with Doug Reside and Alan Liu, “No Round Trip: Two New Primary Sources for Agrippa.”

Cracking the Agrippa Code: How the Disk Worked (Discoveries From the “Cracking the Agrippa Code” Contest in 2012)

In July 2012, Quinn DuPont—at the Information Science department at University of Toronto—ran a “Cracking the Agrippa Code” contest offering hackers “every William Gibson book ever published (except Agrippa)” for solving the mystery of how the code on Agrippa’s disk actually worked to scroll Gibson’s poem up the screen and then, famously, “encrypt” it forever.  The contest produced surprising discoveries.

Matthew G. Kirschenbaum, “Hacking ‘Agrippa’: The Source of the Online Text,” excerpted and adapted from a chapter-length discussion of Agrippa in Kirschenbaum’s book Mechanisms: New Media and the Forensic Imagination (MIT Press, 2008). Kirschenbaum notes: “Mechanisms addresses itself to the textual and technical primitives of electronic writing, with special attention to the qualities of erasure, variability, repeatability, and survivability for electronic objects.” (This advance excerpt was posted on The Agrippa Files with Kirschenbaum’s permission in 2005.)

Item #D51. Video capture of a “run” of William Gibson’s “Agrippa” poem made from playing a disk-image (bit-level) copy of original 1992 Agrippa diskette.

 

Source: original 1992 Agrippa 3.5″ diskette, 1.4 Mb, loaned by collector Allan Chasanoff.

Process: » Disk image (bit-level copy) made using the “dd” copy process. (See Item #D50 on this site: downloadable disk-image file.) » Run of the disk-image copy on a computer using Mini vMac emulator with System 7 book disk (to emulate the functions of the original 1992 Mac platform for which the software on the diskette was created). » Video capture of the resulting run of the poem.

Original Text of Gibson’s “Agrippa” Poem Extracted From Computer Memory During a Run of the Disk

Editor’s Note: The following was contributed on July 17, 2011, by Freek Wiedijk, a mathematician and Assistant Professor of Computing and Information Sciences at Radboud Universiteit Nijmegen, The Netherlands.

 

I have been a long time fan of William Gibson, and was very excited about Agrippa when it appeared, long ago. At the time I was a Mac hacker. However, as I did not have access to the disk in the Agrippa art-book, I could not play with that. Of course I dutifully downloaded, read and stored the “Agrippa” poem once it was “hacked”, but that was it. (It took a long time before I had an idea what the book itself looked like, though.)

So recently I discovered The Agrippa Files site, and downloaded both the disk image and the movie of the Agrippa disk running in emulation.

So then I wondered whether I could have gotten the text of the poem out of that disk myself (without retyping it, just by hacking.) Of course my “classic Mac” skills are very rusty by now, but I still wanted to try. And I indeed did manage to “hack” Agrippa relatively easily, in a crude but effective way.

I did this in three steps: (more…)

Item #D52. Original 1992 Agrippa 3½”, 1.4 Mb diskette belonging to collector Allan Chasanoff used to make the disk-image copy and emulated run of the William Gibson poem featured on this site.

This was the diskette used to create The Agrippa File’s disk-image (bit-level) copy of William Gibson’s poem and its accompanying software, as well as the emulated run of the whole package. In the Digital Forensics Lab at the University of Maryland, College Park, multiple copies were spawned from the original diskette and run through a computer emulating the platform of a 1992-vintage Mac. Multiple instances of Gibson’s poem thus came back to life, ran, and died (disappeared at the hands of the disk’s included encryption program) in the effort to capture the experience of reading the original poem—the experience, that is, minus the sense of one-time-only uniqueness that was part of the core work.

The diskette was loaned by Allan Chasanoff from his copy of Agrippa (editioned “10/95”). Chasanoff’s copy of the book is part of a collection of “book art” he began aggregating in 1990 that has grown to 275 works. The theme of his collection is “the artist and the new ‘disrespect’ he had in opposition to the older cultural devotion to the integrity of the book” (email from Chasanoff to Alan Liu, 5 December 2008).

The creation date of the software on Chasanoff’s diskette is “Wed., Sept. 23, 1992, at 1:13 pm; Modified Wed., Oct. 7, 1992, 10:50 pm.” The Post-It note on the wrapper of the diskette is Chasanoff’s original note (apparently dating from the time of acquisition). For discussion of the digital forensics used to recover and run the software from this disk, see Matthew G. Kirschenbaum, with Doug Reside and Alan Liu, “No Round Trip: Two New Primary Sources for Agrippa.”
