Keyrah makes keyboards of classic computers available to new computers. The board fits the case of a C64, VIC-20, C128, C-16 or Amiga 1200, and turns the computer into a USB keyboard. In addition to that, two digital joysticks can be connected that will act as additional keys (for example cursor keys). It switches between two key-maps that are either adjusted to the daily use under Windows, or especially for emulators like Vice and Amiga Forever. The keyboard adaptor is tested on Linux, Amiga OS, Mac OS and Windows.
