Wasn't there a 6502 pin compatible version of the 65816 at one time?
Whatever happened to that, or am I remembering a bad dream?
I guess they are pretty much pin compatible as it is though.
The 65802. I bought one back in the late 1980s from Jameco, and it worked nearly perfectly in my Apple ][+. The only reason I say "nearly" is that it wouldn't run games with undocumented opcodes, and the ROM was completely unaware of native mode, so you had to take care. I think it was just a
65816 core that didn't output the bank address, but that may not be 100% of the story.
