    I only made changes to the pre-load value, LCDOUT command to display up to 3 digits and the tickcount interrupt handler, where I put in the new:

    Tickcount changes:
    If RunningFlag=1 then
    Thousandths=Thousandths+1

    If Thousandths>9 then
    Thousandths=0
    Hundredths=Hundredths+1

    etc....

    LCDOUT Changes:
    LCDOUT $FE, $C0, DEC3 Thousandths, " Thousandths"

    It doesn't seems right. What went wrong? Did I miss out anything? Getting 1ms counts is very critical for my project, but I just couldn't figure it out.
