The 1541 Ultimate-II is a peripheral developed for the Commodore 64 (C64) by Gideon Zweijtzer.

It’s a C64 compatible cartridge that carries an Action Replay, The Final Cartridge III, Super Snapshot, Retro Replay or TurboAss with Codenet support (whatever the user prefers) and a fully compatible FPGA-emulated Commodore 1541 floppy drive that is fed from a built-in Mini SD card slot with C64-compatible files (e.g. .D64 diskimages or .PRG single program files).

The difference between 1541 Ultimate-II and other SD-based & .D64 mounting cartridges (like the MMC64, Super Snapshot 2007, or MMC Replay, SD2IEC) is that the 6502 microprocessor that powers the 1541 floppy and the 1541′s mechanical behavior (even sound) is fully emulated, making it theoretically compatible with almost anything.

File selection and management is done via a third button on the cartridge that brings up a new menu on screen.

Preview of the new Manosoft C64SD Infinity v2.0.

This project is interesting not only because it’s another mass-storage solution but because it combines already existing solutions to a new and fresh product. Damiano has always followed all the Commdore related websites and forums especially concerning the MMC and SD2IEC projects.

That’s when he got the idea to build a solution for which one doesn’t need soldering, wire cutting or the IEC cable. C64SD utilizes the Datasette pass-through connector to power the SD2IEC circuit. An IEC pass-through connector connects right into the IEC port.

The whole module stand vertical along the back of the C64/128 (or VIC20). The module is fitted with two rather large buttons, one reset and one diskswap/multi-function button.

Remember: with a external power supply the C64SD works fine with Commodore 16/Plus4.

C64SD Infinity new Features:

• TAPE pass-through connector.
• Reset on User Port.
• CPU Type ATMEL ATmega 1284P(128k)
• SD Filesystem for firmware upgrade FAT16/32
• Standard Commodore 128 IEC Cable.

The interface can be purchased on the Manosoft site.

Fixed the SIO2SD Firmware Crash.

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.

Testing the SIO2SD interface for Atari

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.

Device abilities:

• Works with SD (not SDHC) and MMC(FAT12,FAT16 and FAT32 formats)
• Handles ATR (rw), XFD (ro) and COM/XEX (ro) file types.
• 16×2 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.
• Can be configured using ATARI (it’s possible to load configuration tool directly from MCU flash memory, so no SD card is needed)

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).

from Project Homepage:

The 1541-III is a PIC microcontroller controlling an FAT16 MMC/SD card with .D64 files. It is connected to a Commodore computer  via the standard IEC-bus (the serial bus normally used to connect diskdrives and printers).

The main goal of the circuit is to behave like a 1541 disk drive (therefore the name 1541-III). The MMC/SD card contains D64-files (or normal .PRG files).

Here’s the full unboxing of 1541 Ultimate, Gideon has shipped it 21/10/2008 and it arrived six days later.

Now i’m testing with some Demo’s and Game’s (Single/Multi Disk) all work perfectly.
