Specification_1541U Features:

• Full emulation of a real Commodore 1541 diskdrive.
  • Uses .D64 files stored on SD card
  • Supports .G64 files as well (Read only)
  • Configurable ID
  • Configurable ROM (1541/1541C/1541II or custom)
  • RAMBOard memory expansion (16K)
• Secondary 'IEC-drive' for direct access to FAT filesystem.
  • Can be used in stand alone mode to mount disks into the emulated 1541.
• FAT/FAT32 support, with sub-directories and long filenames
• Supports SD V1.1 cards as well as SD V2.0 in High Capacity mode (SDHC)
• C64 cartridge emulation:
  • Final Cartridge III
  • Action Replay
  • Retro Replay
  • Super Snapshot
  • Turbo Assembler w/ Codenet
• Commodore 1750/1764 REU

  • Size selectable from 128K up to 16 MB
  • Can be combined with Retro Replay and SuperSnapshot compatible roms
• Integrated RR-net compatible Ethernet port
  • Available as an option on a new order only!
  • No flimsy stackup board, but fully integrated.
• Flexible freezer menu
  • select, mount, create D64 images, browse disk images
  • create new directories, delete files

Future

As of this writing the 1541U-II is under development. It will feature

• the board itself is about 30% smaller than the 1541U;
• it has a MicroSD connector, instead of a full-size SD;
• it has a real-time-clock function, for correct file time and date;
• it has a larger FPGA, which enables the implementation of more features;
• it has a USB Host port, which can be used to connect USB-sticks;
• it is targeted to have a suitable case for the device.
