@tomcom @KimSJ The Z80 isn't going nowhere. The very first FOSS fabrication of an open source Z80 occurred days ago: https://github.com/rejunity/z80-open-silicon
People can now freely produce their own Z80 clones through companies like tiny tapeout. Z80 lives.
More info: https://tinytapeout.com/runs/tt07/
fabrication plans were finalized June 1st, and the first fabrication run was successful. They are gearing up for a full production run, the new z80s will be available for purchase by October.
