Resources
There is not much about this printer on the Internet, except for a small mention on the Commodore PET wiki page. The printer although branded by Commodore, was manufactured by Mannesmann-Tally.
You may see my printer on a movie in action here. Scroll to the bottom of this page for user manuals (in German).
