Voja Antonić
The designer intended Galaksija as accessible computing for everyone. His philosophy: if you can’t buy a computer, build one. The design prioritised buildability over features.
Legacy
The Galaksija represents computing democracy at its purest—complete instructions published freely, built by individuals. It demonstrated that computing knowledge could spread without commercial channels and inspired a generation of Yugoslav engineers.
