Do you have any idea how hard that would be to recreate? Would it be in the realm of possibilty for an ambitious amateur to fabricate a chip? (Maybe even if not something as relatively new as a SID, possibly something simpler?)
- 0xcde4c3db 7y agoAn ambitious amateur could probably figure out how to fab a chip of the same complexity in small quantities (using e.g. electron beam techniques), but I think recreating the process faithfully, with the same parameters and variation as the original process, would be almost impossible for anything short of a major corporate R&D project.
