8502CPU speed / SuperCPU speed detection

  • Hi!


    In my new version of C128 System Information 7.3 revision 1 is one problem with detection of speed of SCPU/8502


    /8502 correct peek(53296)-251) = MHz
    /65816 at 1MHz peek(53424)=65 / 20MHz peek(53424)=1 > correct
    /65816 if 8502=2MHz >incorrect - always 20MHz: peek(53424)=1


    Exists other address than 53424 where to check SCPU Turbo on/off?


    if know this:
    poke53370,0 to slow down 1mhz
    poke53371,0 to speed up 20mhz


    but peek is always 255


    If can anybody help, please write.


    Many many thanks!
