ByteFest 2026 Turns Prague Into a Four-Day Playground of Vintage Computers

ByteFest 2026 gathers retro computing communities in Prague at Toulcův dvůr from Sept 25-28, celebrating Sinclair, Commodore, Atari, and Amstrad hardware culture.

ByteFest 2026 is underway in Prague this weekend, running from September 25 through September 28 at Toulcův dvůr and bringing together an unusually broad collection of vintage-computing communities. The Czech event is less interested in declaring one machine the winner of an argument that should probably have ended around 1993 and more interested in putting Sinclair, Commodore, Atari, Amstrad and other systems in the same building for demonstrations, software, hardware projects and social tinkering.

This year's gathering has already produced a tangible software surprise in the form of the ZX Spectrum Next version of L'Abbaye des Morts, showing why events such as ByteFest remain relevant beyond displaying immaculate beige computers on tables. Retro-computing festivals increasingly function as informal development conferences: programmers arrive with new homebrew, hardware designers demonstrate expansions, preservationists exchange knowledge and somebody inevitably discovers that a thirty-five-year-old machine refuses to boot precisely when an audience gathers around it.

The location at Toulcův dvůr hosts four days of activity rather than a short convention-hall sprint, giving the event more of the traditional demoscene and computer-club atmosphere than a modern consumer expo. That distinction matters. Vintage computing survives because machines are still being used, programmed, repaired and argued over rather than merely placed behind glass. With contemporary releases appearing for Spectrum, Amiga, C64, MSX and Atari hardware almost weekly in 2026, gatherings like ByteFest increasingly resemble active software ecosystems with extremely old minimum system requirements.
