If you are interested in programming your Apple in assembly, you can ask nicely for your FastChip to include a 65816 processor. It's going to act like a 65802, due to hardware limitations, but otherwise yeah. You get the 16 bit instructions to use.
I've not had any compatibility trouble with mine, which is a 65816.
