- noun The original, 'classic' MUD version 3A which ran at
Essex University from 1980 until 1988, from which virtually all
other MUAs are descended. Also known as MUD1 and SXMUD.
It was played by many people, both
internal and external
to the University.
Although eventually available only during night-time due to
the effects of its popularity on the system, its impact on
on-line gaming has been immense. It was eventually closed down
when Richard Bartle left Essex University to work for MUSE
