Yes, if the 65816 (or something similar) came out in 1978 (the same year as 8086, 6809 and 68000), we&#x27;d probably be in a very different world.   In the late 70&#x27;s, the Apple II was the dominant business machine, because it was the best machine to run Visicalc.   But in the 80&#x27;s, Lotus 1-2-3 on PC completely demolished Visicalc, and the IBM PC hegemony began.<p>Of course, given how badly Apple screwed up the Apple III, it&#x27;s unlikely even the 65816 could have saved it.
