[mast-eries]

Low cost Hard Disk interface compatible with Atari ST family computers,
firmware is refined compared to original one;
and tested on a 520ST TOS 1.04, 1040STFM TOS 1.04, 1040STE TOS 1.06, 1040STE TOS 1.62 and 1040STE with TOS 2.06; with ok results.

On the last video, a game running from hard disk is shown; with "/" key, a savestate is created. After successful hard disk file writing, the game is closed pressing "*" key, and the STE system returns to desktop. A copy of the generated GS00.TOS file is created, renaming it to GS01.TOS; finally the game is resumed loading the copy of the savestate, GS01.TOS . All these operations are performed correctly.
