Honest question: what exactly do you think is great about the 65816? Because I don&#x27;t know much about the 65816 but I don&#x27;t really see the appeal, even compared to the 8086.<p>The 65816 had even less general purpose registers than the 8086, the Direct Page stuff seems like it would be a pain in the ass to use manually and a nightmare for compilers and the instruction set was already saddled with a rather awkwardly implemented backwards compatibility with the 6502 (set this two processor flags and now you are running on a 8bit processor instead of a 16bit one!)
