Macintosh System Tools Version 6.0 floppy disk, signed in black felt tip, "steve jobs." In fine condition, with slight brushing to the ink. A hugely desirable format for Jobs's seldom-seen autograph—known as a reluctant signer, he often declined to comply with the requests of collectors. As a piece of Apple's iconic Mac OS software, boasting Jobs's elegantly stylish lowercase signature, this is a museum-quality piece of computing history.
