The 68k series are rather simple designs by today's standard and should be old enough to have lost patent protection. How hard would it be to reimplement the ISA as a Verilog/VHDL softcore?
- gpderetta 5y agoIt has been done. Search for the Apollo 68080 for example. edit: also relevant is the the PiStorm, a software emulated 680x0 running on a RaspberryPi that plugs into a 680x0 socket. edit2: the MiST/MiSTer are also well known 680x0 open source FPGA implementations.
