Autopsy:
For a new review see the italian version of this article.
from C64Scene Homepage: 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 connector to power the SD2IEC circuit. An IEC connector connects right into the IEC port.
The whole module stand vertical along the back of the C64 (or VIC20). The module is fitted with two rather large buttons, one reset and one diskswap/multi-function button.
SD-CARD Tested:
SANDISK SD-CARD 2GB = 100% WORKING.
CORSAIR SD-CARD 512MB = 100% WORKING.

Manosoft reached a version 2 milestone with his new mass-storage project, C64SD. The Italian developer Damiano Colombari based the C64SD design on the already existing SD2IEC solution.

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:
2010-03-07 – release 0.9.1
- Bugfix: Filling unused REL records used wrong offsets.
- Bugfix: Unbreak case-insensitive matching of FAT file names.
- Bugfix: Fix raw directory mode for D64/D71/D81.
- Bugfix: Tell the display about REL files too.
- Add preliminary support for the ATmega1284P.
