Phantom Access was the name given to a series of hacking programs written by Patrick Kroupa of LOD. The programs were worked on during the early to mid-1980s (1982–1986), and designed to run on the Apple II computer and Apple-Cat modem.

Novation, Inc., is an early modem manufacturer whose CAT series were popular in the early home computer market in the late 1970s and early 1980s, notably on the Apple II. The Hayes Smartmodem 300, introduced in 1981, helped kill off Novation and many other early modem companies over the next few years.
