This program works as a program launcher for Commodore machines. Even if it was originally intended for a device with sd2iec firmware, it works also with any CBM drive (without sd2iec functions of course).

It is a multi-system version derived from the discontinued sd2brwse v.0.6 by Hannu Nuotio (fork() of sdbrowse v.0.7)

The Vic-20 Mega-Cart Installer is based on sys.asm sources of mega-tools by Daniel Kahlin, sort routine by Michael Kircher.

Current supported machines:

• C64.
• C64DTV.
• Vic-20 unexpanded.
• Vic-20 +3K RAM.
• Vic-20 +8K RAM or plus (for FE3 use this version)
• Vic-20 with Mega-Cart.
• C16 / C116 / Plus4.
• C128 in 64 mode.

Autopsy:

The Altera USB-Blaster adapter interfaces a USB port on a host computer to an Altera FPGA mounted on a printed circuit board. The cable sends configuration data from the PC to a standard 10-pin header connected to the FPGA.

You can use the USB-Blaster adapter to iteratively download configuration data to a system during prototyping or to program data into the system during production.

Shadowolf has published a web page where you can download the beta version of  SD2IEC firmware.

SD2IEC is a hardware mass storage device using an SD/MMC card and interfacing with the IEC bus. It is based on the ATmega644 or ATmega1284p 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).
