The author mentions letting them know of any mistakes but there is no method of contact on that page. Perhaps they will see this. The moveable zero-page and stack were not available on the 8502, but on the successor 65CE02 which was CMOS and therefore could also run cooler and faster (up to 10 MHz) than the 8502. The 65CE02 also had the Z register. Also, the C128 MMU can do a lot more than what this article says. Source: https://en.wikipedia.org/wiki/CSG_65CE02 https://en.wikipedia.org/wiki/CSG_65CE02
