Paul Cembura services and sells teletypes from his El Sobrante, CA location. Check out the photos of his stock. For the best atmosphere while you’re checking out the pictures of teletype parts and stock, listen to an ASR-33 teletype printing a document. Wikipedia has a nice article on the ASR-33 teletype. Chances are that when you see or hear a teletype in a television show or film, its an ASR-33. Teletypes have an interesting sort of steam punk feel to them as they are largely electromechanical devices, as opposed to CRT terminals which are largely electrical devices.
