This folder contains the PCB design, HDL, and firmware for a board that allows access to an Acorn Electron cartridge over USB.
I've built one of these boards and implemented the read path, so it can dump out the contents of a ROM cartridge. I've also implemented /INFC and /INFD page access, and successfully downloaded ROM images from a Mega Games Cartridge.
pcb/ - PCB design
cpld/ - HDL for the on-board CPLD (use Xilinx ISE and xc3sprog)
mcu/ - Firmware for the Pro Micro (use the Arduino IDE, selecting the Arduino Leonardo board option)
