SIO2SD boxed interface for Atari XL/XE

15000 Ft

In stock (can be backordered)



SIO2SD is a device that allows you to load games/applications into 8-bit Atari computers via SIO interface from SD/MMC cards.


  • Supported cards:
    • MMC/SDSC/SDHC (and very likely with SDXC, but only FAT32 formated)

  • Supported partitioning schemas:
    • no partition, MBR (Master Boot Record), GPT (GUID Partition Table – EFI)

  • Supported formats:
    • FAT12,FAT16 and FAT32

  • Handles ATR (rw), XFD (ro) and COM/XEX (ro) file types
  • 16×2 LCD display allows to “walk” catalog tree and choose files to load (40×2 LCD displays are also supported)
  • TURBO:
    • speed index can be set by user from 0 to 16, default is 6 (69kb/s)

    • additional turbo mode. I’ve called it 7-bit mode (7th bit of command switches turbo). This is new turbo mode very similar to XF551 turbo mode.

  • All densities with 128B and 256B sectors, including 16MB disks
  • Number of simulated drives:¬†15 + 100
  • Configuration program¬†has to be present on SD card, but any program can be used

  • New ATR files and new folders can be created using SIO commands

  • “Empty disk” mode (ATR file created automatically during format command)

  • Deleting files from card using SIO commands

  • Renaming files and folders using SIO commands

  • Reading and writting all files using SIO commands (inside ATARI folder and subfolders)

  • 100 extra “virtual drives” V0..V99, which can be mapped to any drive from D1 to D15

  • Fast mapping – Drives V0 to V3 have additional, special meaning. When one of keys from K1 to K4 is pressed during start then device overrides mapping of D1 and maps one of those drives to D1 (K1 = V0, K2 = V1 etc.).

  • Builtin very simple TURBO loader (for 7th bit mode – turbo mode similar to one used in XF551)


Full ready to use assembled set:

  • SIO2SD interface with 1602 LCD Display
  • SIO cable with plug
  • Crystal enclousure
