What Z8530 implementation are you referring to? The first post has a picture showing an AMD Z8530 outside of the FPGA.Do you have a reference for the Z8530 implementation? I know of a VHDL one in the Suska project (which I've successfully used to emulate the SCC used in a Sun-3), but it's interesting to have an alternate implementation, in particular in Verilog. But I can't find the original and the file itself doesn't include a license.
