Apple DOS 3.x (1978) gave the Apple II its disk drive — written largely by Randy Wigginton from a contract with Shepardson Microsystems, it was fast, simple, and hacked on by every Apple II owner.\n\nDOS 3.3's 35-track, 16-sector format and RWTS routines became the standard a generation learned assembly against.
