#### What is it?

A new bootable low cost Hard Disk interface compatible with Atari ST family computers, 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.

This device uses a micro SD card as storage. The format is FAT16, readable&writable by a PC computer and the Atari ST/E :)

A ready to use SD card image download link is provided.

Fully assembled and tested via hard disk benchmark software (AHPT94.prg)

#### Why did you make it?

I starting manufacturing this hard disk device, due to alternatives are extremely expensive or not under manufacturing.

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

#### What makes it special?

Its high performance (read around 1 MB/s and write around 700 KB/s) and very low cost price.

As well, it is compatible with SDHC cards; that means you can use almost any micro SD card size.

#### How to operate the device

2- Insert the SD card into the hard disk unit SD card slot

3- Connect the unpowered hard disk unit, into the ACSI port of the unpowered Atari ST/E computer

4- Power up the hard disk unit (5 to 5.5 Volts power source, use the attached USB cable to provide power)

5- Few seconds after step 4, power up the Atari ST/E computer

6- Hard disk unit, and SD card partition will be usually detected; due to its a bootable image

7- If the Atari ST/E falls into an empty desktop, perform a reset of the computer. Normally the system will go to step 6 in these cases.
