ChessEval Journal

A collector entrance to a large historical archive.

ChessEval has existed since 2016. The 2026 lift turns the old archive into a clearer museum-like entrance while preserving the original pages, photographs and Journal materials.

The aim is not to replace the archive, but to make the collection visible, navigable and alive again.

Editorial principle.
Collection pages should identify brands, models, photographs, rare machines and historical notes, then point visitors to the detailed archive and the forum for discussion.
