9500 would mean to start something new, by jumping to a subroutine?.
The value at L01E6 "load to accumulator A" means to place it at a location
for further use.
Now when it says to compare to memory what is that?.....
Branch set carry?.
Add memory to A.
Knowing what is stored at L01E6, ie a timing value would be a clue about
what is being looked at?.
