Frank Buß is working on a new hardware project. He is building a cartridge system for retro computers. The system is divided in two parts, an controller board with an microcontroller, CPLD and SRAM. The second part is a board that can be inserted in the computer (adapter). The cartridge data can be supplied on a SD card or via the USB connection. The microcontroller will simulate a ROM (game cartridge), RAM (RUE) or another application.
