Here is what I have done in 2h 50 . First I wrote a lot of docs, for the keyboard, Serial Monitor, Wozmon etc… This was so boring . But at least now I will be ready to ship soon ! Second, I have fixed the Wozmon list content of address. Before when you was doing FF00.FFFF it was just showing the byte at $FF00 and the byte at $FFFF now it list all the byte between !
