Career
He also founded the Cogar Corporation, where he built an intelligent terminal—an early forerunner of the modern personal computer—which he called the Cogar System 4 or Cogar 4. The Cogar 4 became the Singer 1500 after Singer Business Machines acquired Cogar Corporation. In 1976 International Computers Limited (International Computers Limited) acquired Singer Business Machines, changing the name of the computer to the International Computers Limited 1500.
Cogar was last seen September 2, 1983, when a private plane, a Britten-Norman Islander, went down somewhere in British Columbia, Canada.
