What is UltraSatan?
UltraSatan is a hard disk replacement for Atari ST and other Atari's with ACSI port. It uses SD and / or MMC cards as a storage, which are hot-pluggable.

Why UltraSatan?

• for the same reasons as 'Why SatanDisk?' (MMC and SD cards are cheap and noise-less, etc.)

• it has 2 slots for SD/MMC cards, so replaces 2 SatanDisks attached to 1 computer

• the SD/MMC cards are hot-pluggable, i.e. you don't need to power off and on the UltraSatan when you change the card

• has a battery backed up RTC chip

• up to 4 different firmwares can be uploaded from ST without a need for any additional HW (no flash programmer needed for update)

• it has 1 base (non overwritable) firmware, so even if you screw up the FW update, the device won't become unusable

• it's faster than SatanDisk

Specifications:

• connects to ACSI port of Atari ST

• supports MMC, SD and SDHC cards - tested with cards from 16 MB to 8 GB and works OK on ST

• drivers: ICD PRO (free) and HDDRIVER (commercial) compatible

• open-source - free schematics, firmware, sources, so anyone can build it on his own

• you can change the INQUIRY name of device (the string that shows when hard disk driver shows the currently connected ACSI devices)
