Context

Country: Canada
State/Province: Ontario
Period: 1980-1985
Canada: This part of a Canadian developed & manufactured Telidon graphics decoder-terminal. The Telidon program began on August 15, 1978 and ended on March 31, 1985.
Function: Used to input data into Microtel VTX202 computer terminal for the Telidon system.
Technical: According to Douglas O'Brien, system engineer on the Telidon project, keyboards were usually used for business, office or laboratory environments as keypads were meant for Telidon home systems. This keypad was manufactured from a repurposed calculator. Plastic injection molding was very expensive, so it was cheaper to purchase and modify an existing calculator with a new circuit board. This was especially the case when equipment was manufactured for a field trial, which only used a certain amount of equipment. In 1983, the North American Presentation Level Protocol Syntax (NAPLPS) graphics language develop from the Canadian Telidon system was formalized, ratified and adopted as a world standard for graphics transmission by computer.
Area Notes: Unknown
