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
