A severely physically disabled (quadriplegic) third grade student with high average intellectual abilities was fitted with a computer system adapted for maximum student independence. A scanner, the face of which is an integrated circuit board, was constructed to allow accessibility to the computer by a single switch operated by the student's tongue. (Details of the scanner construction and adaptation are given.) Among difficulties encountered with the system were staff anxiety, space limitations, the need for back-up equipment, the requirement of keeping abreast of new ideas, unanticipated psychological factors, and other unknown complications (such as heat buildup). Sources of equipment, periodicals, and information on organizations are listed. (CL)
