The Data History Association, DDHF, collects, registers and preserves equipment and documents from Danish data development.

Our collection contains a unique documentation of Danish IT history from 1957, which is not found to this extent anywhere else in Denmark. We have machines, manuals, brochures, literature and of course the old software, which we load into our bit archive so that it is preserved for posterity.

What is unique about the association is the many volunteers who keep the old machines running so that history can be experienced and not just viewed.
