        With all due respect to the emulator, could the additional (
initialization ) code have pushed the program over a page boundary,
that is not properly handled by the isr or other subroutine ?????
        I'm not sure how similar the memory maps are between the 'C67
and 'F877, so I may be talking through my hat, but I seem to remember
someone had started their registers too low in memory.
