From the project
SCSI-1 Emulator for 8-bit Acorn computers such as the BBC Master and BBC Model B
BeebSCSI is a Micro SD Card based SCSI storage emulation for the Acorn 8-bit range of microcomputers including the Acorn BBC Model B (with ADFS) and the BBC Master 128.
Please see the project wiki for detailed documentation on BeebSCSI
The project is divided into several sections:
BeebSCSI_AVR - This is the AT90USB1287 microcontroller firmware (written in GCC)
BeebSCSI_CPLD - This is the Xilinx XC9572XL CPLD firmware (written in ISE Verilog)
