This is a development board i designed and built and is centered around the EPM1270T144C5N intel CPLD. I built this board to test the Ben Eater 8 bit breadboard computer which i replicated on an FPGA with VHDL. The board is a 2 layer board designed with altium and the altium files can be found here.
