The SIO2SD is a device that allows you to load games/applications into any 8-bit Atari XL/XE computers via SIO interface from SD/MMC cards.
Changelog:
RC1 -> RC2
- Fixed LCD handling bug (RC1 doesn’t work without LCD)
- Added “swap” command (K3 in VDISK MODE swaps mappings of D1 and D2)
- Added “rol4″ command (K4 in VDISK MODE moves mappings D1<D2<D3<D4<D1)
- Added “ror4″ command (SHIFT+K4 in VDISK MODE moves mappings D1>D2>D3>D4>D1)
RC2 -> RC3
- Fixed xex-loader.
- Added new key combinations OPTION+SELECT and OPTION+START to turbo-loader (new turbo IRQ locations: $700 and $500).

A new version of the firmware for the interface 1541 Ultimate II is released. This version only runs on the Ultimate-II!
Major improvement in latest release:
- Config menu is now ‘hot’, meaning that all settings that can be applied when exiting the menu will be applied immediately without reboot.
- Audio options added.
- Stereo SID emulation added.
- Initial support for domark cartridges added; not yet tested (and no support from the menu in this release).
- Improvements made in file system handling.. (It’s not ‘clean’ yet, but delete and rename now work)
- Issue solved that caused errors when more than one cluster was used for a directory.
- Bug fixed that caused a crash when partition list was skipped.
- Some additional testing with SID support.
- Created module for selecting audio options in the Ultimate configuration menu. Address for second SID now configurable.
- Some experiments done with EM1010 USB to Ethernet module. The module doesn’t comply with the USB philosophy of interrupts.. it *always* gives an interrupt every poll.. (wrong!) But nevertheless, managed to send a DHCP discover and receive a reply from the router. :) (not yet functional in this release)
- Command Interface created and handler set up for testing VHDL. (not yet functional in this release)
- Cartridge Logic restructured to make it a little more plug and go.
- Reading of ISO9660 added (both as .iso file, as well as from external USB CD-ROM..)
- Partition list skipped when there is just one.

The SIO2SD is a device that allows you to load games/applications into any 8-bit Atari XL/XE computers via SIO interface from SD/MMC cards.
Changelog:
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)
TURBO:
- 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.
Number of simulated drives:
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).

Micro SwinSID (SwinSID88) is a hardware replacement for legendary SID sound chip which was placed in every Commodore C64 computer and other devices. Firmware update (27022011):
- This new firmware brings 6581 filter emulation by connecting B0 AVR pin to ground (on the Photo).
- Filter distrortions are still not emulated, only filter cutoff is affected.

The HxC Floppy Drive Emulator is a software and hardware system created by jfdn aka Jeff.
The aim of this project is to replace the floppy disk drive by an electronic device emulating the floppy disk drive (list of supported Computer/Hardware).
There are two differents emulators:
- A USB version which allows to connect the floppy disk drive interface of the computer to a PC via a USB cable.
- A SDCARD version which allows to emulate floppy disks which images are stored in a SDCARD.
Release notes for the SD HxCFloppyEmulator firmware upgrade v1.5.1.0:
- Direct access mode : Bad Write mode corrected.
- Display: Negative Track position bug corrected.
- Internal : write mode selection code clean up.

Micro SwinSID (SwinSID88) is a hardware replacement for legendary SID sound chip which was placed in every Commodore C64 computer and other devices.
On the Photo you can see the AVR ISP homebrew Adapter for programming the firmware.
Firmware update (10012011):
- Much improved ADSR envelope fading based on a real SID counter design.
- More soft filter.
Hardware tip:
To increase audio quality and volume level replace R4 (2k2) resistor with 1K. This will boost volume by about 50%
