In some respects that is true even back then when instruction cycle
time were in the 2-10uS bracket. You did get to see the average
addresses that were freqently accessed. However, front pannels also
posessed the ability to stop the cpu, and single step or single
instruction advance it. A true front panel on a PC would have to be able
to do that and that is no small trick considering the caches, Dram refresh
and other dynamic timings.
