RS232 Interface for the CPC by [[Schneider]]. Schneider is the german distributor for Amstrad CPC hardware (however, this
interface seems to be Schneider's own invention, not an Amstrad product).
The shape of the case dates back to a Schneider BTX modul (which was being intended to be plugged into Schneider Television Sets). Apparently Schneider produced too many cases, and re-used them for the RS232 interface.
