Zum Auffrischen und Schmunzeln . . .

. . . sind diese Museums-Seiten hier gedacht, denn viele wissen nicht mehr oder noch nicht, wie es damals angefangen hat und wie das wirklich funktioniert mit den Tonband- und den Magnetbandgeräten aus alter Zeit. Viele Bilder können Sie durch Anklicken vergrößern, auch dieses.
