Data Media Disc System
From CPCWiki - THE Amstrad CPC encyclopedia!
An early disc solution for the CPC 464.
Manufactured by the German company Data Media.
Avaliable in two versions with two or four drives. The four drive version was able to store up to 3.2Mb of data.
The disc operating system was called FDOS and was stored on the controler board in an 8Kb eprom. Data Media also delivered patches that made the drives availiable under CP/M.
This controler was unlike all later disc controlers for the CPC based on the WD2797 chipset.
As a special feature the controler board had an integrated RS232 interface.
