He replied but I honestly think he's misremembering and/or forgot about the Z/80 card that was needed to run WordStar on an Apple II. He doesn't really answer the question that you asked:
> The 6502 CPU is the one that was used inside the early Apple computers. You added an 80 column card, and for a big discount and no service contract you had something that would replace the popular Wang word processing machine. The spreadsheet and word processor drove the computer revolution.
I'm as confident as it's possible to be about 40 year old software that there was no WordStar for the Apple II that didn't require a Z/80 card (i.e., there was no native 6502 version.)
I was able to find some reference to an Irish dev team that made the ports, but the 6502 port was scrapped in favor of CP/M-86. Brain dead move imo. I updated the article. Thank you for your corrections to the record :-)
Edit: Actually just found more info, and it would appear that it was actually just the dual effort of 8086 dos and cpm that killed all efforts at 6502, and the team in Ireland were never tasked with it. So, it would seem that that port never get any further than Barnaby having run it through a cross assembler.
