The OSXA repository contains the design files for an addon to the original xbox video game console. The design is based on the LC4064V CPLD from Lattice Semiconductors and the SST49LFXX0X line of LPC flash devices from Microchip. It includes both the hardware (schematic and layout) and software (vhdl sources) required for its implementation.
The Schematic and Layout was done using the free version of DIPTRACE (http://diptrace.com). In addition, the vhdl HW design was implemented using the Lattice ispLEVER Classic software and a FTDI C232HM (https://www.digikey.com/product-det...tional-ltd/C232HM-DDHSL-0/768-1106-ND/2714139) cable for programming. Any programmer based on the FTDI FT2232 would work just fine.
