SIO2SD
Quick Guide
SIO2SD
is a device that allows you 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 - Warning !!! Software up to version
2.0 had a bug in FAT12 code - FAT12 is typically used by Windows XP for 16MB cards)
•
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)
USAGE
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). To perform firmware upgrade, just put SIO2SD.BIN (28k version) into
the root directory, then insert card with this file and press proper key combination. 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.
On PCB there are five keys placed like this:
K1
K3
K2
K4
SHIFT
•
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")
