Finding The Problem - HP 1652B Getting Started Manual

Finding the
Problem
You look at this listing to see what the data is in states + 0000 through
+ 0004. You know your routine is five states long.
The 68000 does address location 8930, so you know that the routine is
addressed. Now you need to compare the state listing with the
following correct addresses and data:
+ 0000 008930 B03C
+ 0001 008932 61FA
+ 0002 008934 67F8
+ 0003 008936 B03C
+ 0004 00892E 61FA
As you compare the state listing (shown below) with the above data you
notice the data at address 8932 is incorrect. Now you need to find out
why.
