In Bad König, Westenwald, Germany, Matthias Schmitt and his wife have developed a museum dedicated to Technik called TECMUMAS. Mostly retro computers from the early days to the nineteens.

Here some photos of my visit in 2025, when I was given the opportunity to see and photograph MOS Technology KIM-4 and KIM-5 devices and the Synertek MDT 1000.

Besides those systems TECMUMAS is home to about 1400 computers and what comes with it: manuals, books, monitors and more.

The museum has a large room to display a part of the collection, regularly refreshed with objects of the collection absed upon a theme.
