was the first popular MUD
which college students began playing in the 1980s
. It was written, mainly, by Alan Cox
, also known as Anarchy, who had been a player on the original MUD at Essex University 
. It is named after the [[University of Wales Aberystwyth|University of
Aberystwyth, Wales]]. Several dozen AberMUDs remain in operation, but in 2002
they have few players.
Nearly all AberMUDs in operation today are not based on the latest release, Aber V, but on a descendant of AberMUD IV called Dirt, which was written by Alf and Nicknack.
