Are they completely unused or is the Nut processor using them for something that is just not visible to the 41 OS? I was able to YPOKE a value into 800800 then YMCPY 800>801 then YPOKE a new value into 801800 then YMCPY 801>800 then YPEEK the changed value from 800800. So it looks like YPEEK/YPOKE and YMCPY can read and write from this location! |
