When entering the Monitor mode, if I just hit the enter key repeatedly, it shows me this HEX data. Do you know what this data is?
What does B800, B808, B810 mean? What does "B" stand for? What is the actual HEX data? Is that the ROM code itself?
Moreover, when I press Control + E for "examine" it shows me the same text each time:
A=FF X=98 Y=DS P=00 S=B7
What does A, X, Y, P and S stand for?
I'd very much like to make sense of the Monitor, but I don't know where to start.
