SIO2SD Revised 2k20 – Mass storage for Atari XL/XE

 

Hardware, manuals, FAQ, and other info on manufacturers website – HERE

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

Features

• Works with SD/MMC (FAT12, FAT16, and FAT32 formats
• Handles ATR (rw), XFD (to), and COM/XEX (ro) file types
• 16×2 LCD display allows to browse the catalog tree and choose files to load
• Handles SIO with turbo (allows to set speed index from 1 to 16, default is 6 (69kb/s), in versions 1.x speed index was always 10 (51kb/s))
• All densities with 128B and 256B sectors, including 16MB disks
• Handles drive d1 to d8 (up to version 1.2 only d1 to d4 drives were available)
• Can be configured using ATARI (it’s possible to load configuration tool directly from MCU flash memory, so no SD card is needed)

CHANGES:

• Hirose heavy-duty SD SLOT (push-pull), used in HXC Floppy Emulators
• polarity protection with indicators led (OK/NOK polarity)
• extra keys and LEDs connectors for customers that fir device inside case/atari/etc

Usage

• FAT formatted SD card needed
• In the root directory, create ATARI folder. Here you can place folders and files. This is the start folder for SIO2SD. It’s a better idea to use folders with up to about 100 files than one big folder with many, many files.
• On the first use of a newly formatted card, SIO2SD will create a SIO2SD.CFG file in the root directory, where the configuration will be stored (files to disks mapping).
• Note: the directory named ATARI must be present on the card or else SIO2SD won’t recognize the card and won’t perform the upgrade.

Keys:

• K1: next Atari drive (D1, D2,..)
• K2: next file/folder
• K3: parent directory (cd ..)
• K4: go to folder/map file to current Atari drive
• SHIFT+K2: firmware upgrade
• SHIFT+K4: turn off current Atari drive (“eject disk”)

 

Options:

• SIO high speed
  • off
  • hs index from 1 to 16 (6 is the default setting)
• CFG tool load (when to override D1 to load configuration program)
  • never
  • startup+shift – only when SHIFT was pressed during startup (power on)
  • every startup
  • no card – only if SD card is not inserted (default setting)
  • shift pressed – SHIFT always causes D1 override (tested on every SIO ‘S’ command on D1 – available from version 2.2)
• LED mode
  • SD read/write – first LED shows SD reads, second LED shows SD writes
  • SIO read/write – first LED shows SIO reads, second SIO writes
  • SD act/SIO act – first LED shows any SD activity, second any SIO activity
• Device id (number of the device for SIO2SD.XEX – available from version 2.2)
  • values from 0 to 3
• Write-protect (write protection in ATR files – available from version 2.2)
  • never – ATR’s are always R/W (write protect flag ignored)
  • obey ATR flag – obey ATR write protect flag – default
  • always – ATR’s are always R/O
