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.


Results: The unit works perfectly; such example loading the 3.5 MB size of current Metal Slug port takes around 12 seconds (aprox. 650 KB/s read and 400 KB/s write).
Tested against old SD cards, such 1 GB card; 4 GB SDHC and 8 GB SDHC. All these are detected and works correctly!

Writing and reading from the hard disk interface:

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.

Each unit is completely built and tested,
price is 33€ + tracked shipment (6€ for Spain or 9€ for Europe; 10€ for America, Canada, EE.UU. , 11€ for Japan , Australia and Alaska).




Lower cost and better SD card compatibility than any Satan disk, and much lower price than UltraSatan.
Its the Atari ST hard disk suitable for the masses,
