German A german company that produced the [[Wiedmann BTX Modul]] for CPC or Joyce.
The company does still exist in 2010, and they do even still have [[Schneider ]] and [[Amstrad ]] logos on their webpage, : http://www.wiedmann.com - however, they seem to be focusing on older (pre-computer) hardware now, see screenshots below.
