Fabricating a custom chip costs several million dollars, which is kind of a non-starter for such a niche product. Is it theoretically possible? Maybe, there are high-res die photographs used for reverse engineering and improving simulator accuracy. But I doubt this is accurate enough to fab an exact replica. http://visual6502.org/images/pages/MOS_6581_SID_die_shots.html http://visual6502.org/images/pages/MOS_6581_SID_die_shots.ht...
