I made a little batch of 12 units of the SATANDISK. This new version have some good improvements:
PCB made from ground based on the Jookie's schematics.
Micro USB connector to use with an 5V Android compatible power supply (at least 1a).
New 3v3 regulator and better decoupling caps.
Sd card protection in case of removed while power on.
No ACSI to Satandisk cable required, you just plug the satandisk on the back of the Atari.
Parts required in order to make it work:
SD card with at least 1GB required. Some 4GB sd card or mmc card with adapters are not compatible with SATANDISK firmware. You need to find a good one. Usually an old 2GB sd card will work.
5V/500ma or 1A Android compatible power supply (micro usb b).
An Atari ST
Know bugs and tips:
Cold boot issue – in some cases the TOS does not detect the SATANDISK on the first boot, so if you don’t see activity led working, once the TOS desktop is available, just reset the ST and on the next boot, the SATANDISK will be detected.
HDDRIVER bug with cards > 1GB. The total space is not showed properly, so some areas of the SD aren’t accesible.
