QT Computer Systems SYS-I6

[Vin6]

The QT Computer Systems SYS-I6 was a notable Canadian-made minicomputer recognized for its advanced multi-user capabilities, allowing several users to work on the system simultaneously-a valuable feature in the era before widespread personal computing. Its claim to fame lies in its support for multi-user environments, which made it an important tool for organizations needing shared computing resources, and it stands out as a rare example of a domestically produced computer in Canada’s early computing history.canada logo
