The threshold for "real computer" rises with time. As of

mid-1993 it meant multi-tasking, with a hard disk, and an

address space bigger than 16 megabytes. At this time,

according to GLS, computers with character-only displays

were verging on "unreal". In 2001, a real computer has a one

gigahertz processor, 128 MB of RAM, 20 GB of hard disk,

and runs Linux.
