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:

2009-05-20 – release 0.8.1

• Fix uIEC/IDE SD card change detection.
• Dreamload support for uIEC.
• Mark the RTC time as valid after setting the clock.
• Delay SPI initialisation until absolutely required.
• Show disk change confirmation even when the error blink is active.
• Exit the FC3 fastloader if ATN is active.
• Fix indentation of 1000+ block files.
• Remove 0-byte from the long version message.
• Fix multiple save-with-replace bugs.
• Ignore directories when matching file name wildcards.

I held off on announcing uIEC/SD availability until I had some stock (impatient folks, you know who you are , but I do now have some stock 90 units).

Since uIEC shares the same firmware (kudos to Ingo Korb, who does not get enough recognition for this fine piece of code) as the recently announced SD2IEC, I’ll spare everyone rehashing the similarities and just note the differences:

Features:

• uIEC/SD is currently the smallest known CBM drive (1.5″ x 1.5″ by 0.3″). Perfect for embedding in your favorite machine, drive, or calculator (shout out to Tone007, who stuffed one in a CBM pocket calculator)
• uIEC/SD shares the same 128kB Atmel AVR 8-bit microcontroller as the rest of the uIEC line. With 51kB used for firmware, there’s plenty of room left for the future.
• uIEC/SD comes complete for use with IEC connector and power supply cassette port connector. VIC/64/C128 users can simply plug the wires in and use. (SX64/+4/C116/C16 users need to source 5V elsewhere, let me know before purchasing if you’d like an alternate connector)
• Although not yet defined for use, uIEC/SD offers an additional switch line and programmatic LED for future use.
• uIEC/SD not only supports SD and SDHC cards, but either SD or SDHC cards can also be used for updating the firmware (new feature, older firmware update software only supports SD cards)

SJLOAD is a C64/C64DTV software fastloader. Its main difference from normal fastloaders is that it only works with Jiffy-enabled drives and uses the Jiffy protocol. This makes it handy for people who have a Jiffy-enabled drive (also new hardware such as SD2IEC) but do not want to make the hardware changes necessary for exchanging the C64 kernal.

SJLOAD speed is a bit higher than normal Jiffy since SJLOAD uses the same protocol but a different implementation (it disables the VICII during load etc.). With an SD2IEC, SJLOAD is about 15% faster than a normal Jiffy kernal.

SJLOAD is loosely based on VDOS (1986) by Edward Carroll. However, the fast loading routines have been replaced completely by 1570.
