This board is a drop-in replacement for the 8088 CPU inside of the PCjr. It utilizes a Xilinx Spartan-6 FPGA and 512KB of SRAM.
The CPU core is the MCL86 and can be run in cycle accurare mode as well as non-cycle accurate which allows the PCjr to run 4X faster than an IBM PC and 20% faster than the IBM PC AT!
