The Western Design Center 65c816 is an underdog CPU from the 1980s. It was never the best available CPU of its time and it was never the cheapest. It was a 16-bit CPU from a time of transition from 8 bits to 16 and 32 bits, released around the same time as the first fully 32-bit CPUs. But it’s an interesting CPU, even if it doesn’t get the attention other contemporary CPUs received. It was introduced the week of December 12, 1983.
