Wozniak did complete a floating-point library for the 6502 and published it in the August 1976 edition of Dr. Dobbs. This library was later made part of the ROMs for the Apple II. Wozniak began work on back-porting the floating-point code into Apple BASIC, but got sidetracked in the task of designing a floppy disk controller for what became the Disk II. Mike Markkula said the company would go to the Consumer Electronics Show in Las Vegas if the disk system was ready in time, so Wozniak and Randy Wigginton worked on it non-stop through the 1977 holidays.
