Hi, Hans!
I couldn't have done any better!
Thanks for honoring me with your kind citation :)
I was thinking about starting the page zero use at $E6 for Wozmon.
KIM starts using at $EF and Wozmon would finish at $EE. This way you are not going to have any collision with the part used by KIM and with the space freed in the middle of page zero the user would be able to run some programs there, inside Wozmon, like the Memory Test from The First Book of Kim. It's not clear to me why Wozniak preferred to start page zero use at $24. Perhaps Jim has clue.
Anyway, it's just a thought. I tried here and it works perfectly starting at $E6.
Thanks for your kind remarks!
