It was released in January 1983 as the successor to the Apple II Plus. The e in the name stands for enhanced.

- cat (Unix) (Wikipedia)
cat is a standard Unix utility that reads files sequentially, writing them to standard output. The name is derived from its function to (con)catenate files (from Latin catenare, “to chain”). It has been ported to a number of operating systems. ¶ The other primary purpose of cat, aside from concatenation, is file printing — allowing the computer user to view the contents of a file. Printing is the most common use of cat.
