It is an adapter for the oscilloscope designed for analog TV coding. With this device you can watch the selected single TV line on the screen. Boards were made in thermal transfer method. Pictures show one system on „spider”. It turned out that buttons „up” and „down” do not operate stable (contact bounce) and the system was to be built quickly.
