EMACS is a programmable computer text editor with an entire LISP system inside it. It was originally written by Richard Stallman in TECO under ITS at the MIT AI lab; AI Memo 554 described it as 'an advanced, self-documenting, customisable, extensible real-time display editor'. It has since been reimplemented any number of times, by various hackers, and versions exist which run under most major operating systems. Perhaps the most widely used version, also written by Stallman and now called 'GNU EMACS' or GNUMACS, runs principally under UNIX. It includes facilities to run compilation sub-processes and send and receive mail. Other variants include GOSMACS, CCA EMACS, UniPress EMACS, Montgomery EMACS, jove, epsilon, and MicroEMACS.

LISP (from 'LISt Processing language', but mythically from 'Lots of Irritating Superfluous Parentheses') is a computer programming language. It is a language based on the ideas of (a) variable-length lists and trees as fundamental data types, and (b) the interpretation of code as data and vice-versa. It was Invented by John McCarthy at MIT in the late 1950s, and is actually older than any other high-level language still in use except FORTRAN. Accordingly, it has undergone considerable adaptive radiation over the years; modern variants are quite different in detail from the original LISP 1.5.

The PDP-10 (Programmed Data Processor model 10) was a computer that made timesharing real. It was adopted in the mid-1970s by many university computing facilities and research labs, including the MIT AI Lab, Stanford, and CMU. The
PDP-10 was eventually eclipsed by the VAX machines (descendants of the PDP-11) when DEC recognised that the 10 and VAX product lines were competing with each other and decided to concentrate its software development effort on the more profitable VAX. The PDP-10 was finally dropped from DEC's line in 1983, following the failure of the Jupiter Project at DEC to build a viable new model.

Spacewar is a space-combat simulation game, inspired by E. E. 'Doc' Smith's 'Lensman' books, in which two spaceships duel around a central sun, shooting torpedoes at each other and jumping through hyperspace. The game was first implemented on the PDP-1 at MIT in 1960.
SPACEWAR aficionados formed the core of the early hacker culture at MIT. Nine years later, a descendant of the game motivated Ken Thompson to build, in his spare time on a scavenged PDP-7, the operating system that became UNIX. Less than nine years after that, SPACEWAR was commercialise as one of the first video games.

X Windows or more properly the X Window System (also known as X11) is the standard graphical user interface for the Unix family of operating systems. X11 was first developed by Digital Equipment Corporation (DEC) and the project Athena at Massachusetts's Institute of Technology (MIT) and first released as X11R1 in September 1987. XFree86 is the freely available implementation of
X Windows for 80x86 family computers (PCs), ad it was developed by a group called the XFree86 team in 1992. X Windows is more than a simple interface, it is a network-based system comprising a server and clients. X11 #X Windows

The Anti-MIT Virus is an encrypted computer virus written by First Strike, which infects .COM files including COMMAND.COM. The virus is loaded into memory by executing an infected program and then affects the computer's runtime operation, corrupts program or overlay files. The virus will not infect files smaller than 500 bytes or longer than 19000 bytes . Infected files may be easily detected as the seconds field of the time stamp are set to the value 62.
