A large font virtual terminal interface
Ephraim P. Glinert · Communications of the ACM · 1984
A large font software interface running under UNIX 1 is of great assistance to the severely visually impaired in the interactive use of computers. The interface, which functions as a virtual terminal as far as other processes are concerned, displays all characters (both user and system generated) at user-selectable degrees of magnification, yet is compatible with any standard CRT / keyboard terminal .
