Sio2sd is a device that allows you to load games/applications into 8-bit Atari computers via SIO interface from SD/MMC cards.
- 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 (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 drives 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)
Lotharek`s design version differs from others available:
- Firmware: latest 3.1 RC2 - Lotharek customized
- SIO HI speed patch (4k7 resistor beetween SIO DATAOUT and +5V)
- new design FULL smd board, fully made at automatic assembly lines - not home done handycraft
- fixed voltage regulator for SD/SDHC Cards (now works stable with ANY SD/SDHC card)
- You have to format (FAT) SD card using computer
- In root directory create ATARI folder. In this folder you can place folders and files. This is the start folder for SIO2SD. It's a good idea to use folders with up to about 100 files than one big folder with many, many files.
- On the first use of a new formatted card SIO2SD will create SIO2SD.CFG file in root directory, where 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.
- K1: next atari drive (D1,D2,..)
- SHIFT+ K1 - previous atari drive ( D15,D14..D1)
- K2: next file/folder
- SHIFT + K2 - previous file/folder
- K3: parent directory (cd ..)
- K4 (ENTER) : go to folder / mount file to current atari drive
- SHIFT+k4: turn off current atari drive ("eject disk")
- sio high speed
- hsindex from 1 to 16 (6 is the default setting)
- cfg tool load (when to override D1 to load configuration program)
- 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 cause D1 override (tested on every SIO 'S' command on D1 - available from version 2.2)
- LED mode (meanig of LEDs)
- 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 device for SIO2SD.XEX - available from version 2.2)
- 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
- cased sio2sd device with SIO CABLE

1. Can i only read from SDCARD or can i also write to it? So can i use this device to save e.g. Atari Basic Files from Atari to SD with the normal Floppy commands on atari?
Yes, but not directly to SD CARD. You can read/write to ATR file. Probably You already know ATR Files from Atari Emulators (ATR file is a disk image). If You create such an (empty) image on SDCARD and use sio2sd box, then the Atari "sees" this ATR image as an empty floppy disc, and You can read and write to this "floppy". Also with Basic loaded. You can use up to 15 ATR files, assigned to drives D1: --> D15 and access them, like regualar floppies.
2. My games doesn`t load. I get garbage on the screen.
Most of the games for atari 8bit needs BASIC to be DISABLED - it means You have to press and hold ATARI OPTION KEY at power on.
3. What is firmware version of device ?
Fimware uploaded is last one- version 3.1 RC2 / www.lotharek.pl customize
