from 1541 Ultimate homepage:
- Last firmware version: 2.0RC5 is now downloadable from the download page.
- Ultimate-II sources released!
You can access them through http://svn2.xp-dev.com/svn/1541UltimateII/.
For those who know how to use SVN, you can do a checkout to create a local working copy by typing:
svn co http://svn2.xp-dev.com/svn/1541UltimateII/trunk
in an empty directory. I am working on a short manual, and on access to the tools needed to build the project. This time, the FPGA sources have been released as well. ;-)

SD2IEC is a hardware mass storage device using an SD/MMC card and interfacing with the IEC bus. It is based on the ATmega644 microcontroller from the Atmel AVR microcontroller family.
The most prominent use of SD2IEC is emulation/replacement of a Commodore-1541 disk drive for a C64. Hardware and the microcontroller’s firmware is available as open source (GPL).
Changelog:
2010-06-21 – release 0.9.2
- Bugfix: Rename was broken on FAT.
- Turbodisk is now disabled when running on internal RC clock.
- Button debounce timeout increased.

from 1541 Ultimate homepage:
Finally, the software for the 1541 Ultimate II is finished. In the last two weeks, an enormous amount of work has been done:
- USB is now working stable, including insertion and removal. (My external 500 GB harddisk was detected flawlessly!)
- Support for USB devices with multiple LUNs (like card readers)
- GCR (G64) supported added, including write (the Ultimate-I couldn’t do this)
- T64 file support re-integrated.
- Tape support, using TAP files (I needed to test the hardware anyway!)
- Comprehensible menus.
- Real time clock functional (still need a clock widget…)
- I made a wooden mould, to simplify closing the plastic cases without damaging them.
The plan is, to ship the first 40~50 units this coming Wednesday! The remaining units will follow as soon as possible! Thank you for your patience!
