Vintage Andy Warhol computer art, found! The press release of the Studio for Creative Inquiry makes for fun reading.

The video of Warhol drawing on an Amiga--in this case, of Blondie's Debbie Harry--mentioned in the text is below.
For the curious, I'd recommend the technical report (PDF link) describing how the data was retrieved. This is computer archeology in action, people, culturally and technically important. The Verge's Rick McCormick has a brief article that may be of interest.

A multi-institutional team of new-media artists, computer experts, and museum professionals have discovered a dozen previously unknown experiments by Andy Warhol (BFA, 1949) on aging floppy disks from 1985.
The purely digital images, “trapped” for nearly 30 years on Amiga® floppy disks stored in the archives collection of The Andy Warhol Museum (AWM), were discovered and extracted by members of the Carnegie Mellon University (CMU) Computer Club, with assistance from the AWM’s staff, CMU’s Frank-Ratchye STUDIO for Creative Inquiry (FRSCI), the Hillman Photography Initiative at the Carnegie Museum of Art (CMOA), and New York based artist Cory Arcangel.
Warhol’s Amiga experiments were the products of a commission by Commodore International to demonstrate the graphic arts capabilities of the Amiga 1000 personal computer. Created by Warhol on prototype Amiga hardware in his unmistakable visual style, the recovered images reveal an early exploration of the visual potential of software imaging tools, and show new ways in which the preeminent American artist of the 20th century was years ahead of his time.
The impetus for the investigation came when Arcangel, a self-described “Warhol fanatic and lifelong computer nerd,” learned about Warhol’s Amiga experiments from the YouTube video of the 1985 Commodore Amiga product launch. Acting on a hunch, and with the support of CMOA curator Tina Kukielski, Arcangel approached the AWM in December 2011 regarding the possibility of restoring the Amiga hardware in the museum’s possession, and cataloging any files on its associated diskettes. In April 2012, he contacted Golan Levin, a CMU art professor and director of the FRSCI, a laboratory that supports “atypical, anti-disciplinary and inter-institutional” arts research. Offering a grant to support the investigation, Levin connected Cory with the CMU Computer Club, a student organization that had gained renown for its expertise in “retrocomputing,” or the restoration of vintage computers.
