Secure Digital (SD) is a flash memory (non-volatile) memory card format used
in portable devices, including digital cameras, handheld computers, PDAs and
GPS units.  SD cards are based on the older MultiMediaCard (MMC) format.

SIO2SD is a device which makes it possible to load games/applications into
8-bit Atari computers via SIO interface from SD/MMC cards.

Device abilities:
- Works with SD/MMC (FAT12,FAT16 and FAT32 formats)
- Handles ATR (rw), XFD (ro) and COM/XEX (ro) file types
- 16x2 LCD display allows to "walk" catalog tree and choose files to load
- Handles SIO with turbo (speed 51200kb/s - hsindex 10)
- All densities with 128B and 256B sectors, including 16MB disks
- Handles drives d1 to d4 (special version d1 to d8 available)

Subject: 3.11) How can I use a USB flash drive with my Atari?

==> SIO2USB, by ABBUC Regional Group Frankfurt / Main

USB flash drives are NAND-type flash memory data storage devices integrated
with a USB (universal serial bus) interface.  They are typically small,
lightweight, removable and rewritable.

The SIO2USB Interface is a peripheral device that can be attached to an ATARI
8-bit computer using the SIO-Bus.  It emulates one or more ATARI Floppy-
Drive(s) and does not require any special drivers or Operating-Systems, it is
fully compatible with all ATARI DOS Systems and extensions.  Because the
device is connected to the SIO-Bus, it is not necessary to open or modify the
ATARI.  The device is powered by the SIO-Bus and does not need an external
Power Adapter.  The data are stored on standard USB Mass Storage Devices (USB
FLASH Drives) as ATARI-Imagefiles (ATR or XFD) on a standard FAT filesystem.

SIO2USB features:

o Can boot an ATARI 8-bit Computer without physical Floppy Drive
o Emulation of up to 3 (virtual) Disk drives simultaneously
o Simple device, attached to SIO-Port, no modification of computer necessary
o Mixed operation of real Floppy and SIO2USB possible
o Fully compatible with all ATARI DOS and OS and all ATARI compatible
   extensions
o Storage of ATARI-Imagefiles on standard USB FLASH Drives
o Configuration of the device by built-in keys and LC-Display or
   configuration program on the ATARI
o Built-in Real Time Clock (RTC)
o Power supply for the device and USB FLASH Drive from SIO-Bus
o Updated SIO2USB Firmware can be applied from within the ATARI (no
   additional device or computer required)
o Updates available via Internet (USB FLASH Drive) or direct from the ATARI
   (real Disk Drive)
