High Quality Content by WIKIPEDIA articles! Satandisk is a Secure Digital and MultiMediaCard adapter for Atari 16-bit computers, such as the Atari ST. It is out of the pre-production stage and units have now been shipped to most customers. It is an interface that allows the connection of an SD or MMC card to be attached to the ACSI (Hard Disc) port of Atari Computers, and has been tested to be compatible with TOS versions 1.02 to 2.06. The maximum supported size is 4GB. The device appears to the system as any regular ACSI attached hard disc, but has so far only been successfully used with the proprietary and commercial HDDriver driver package.
