I restored the flash chips to their original locations, and confirmed 
that everything was working as before. Then I ran the flash erase 
with several of the other jumper configurations. After finding the 
correct jumper configuration, it allowed me to install the latest 
firmware, and everything appears to me working well. 

If anyone else wants to try this, you need to have both the jumpers 
closest to the SIMM's edge connector open, and the other two shorted. 
You will have to run the secure flash erase to reformat the SIMM (hold 
"view/trace", "ESC", and "return" while turning on the analyzer. The 
screen will be blank, but you can tell it's working by checking for 
the Vpp voltage of one of the chips. Give it about 10 minutes, and 
then pull the plug to turn it off. After erasing the flash, it won't 
work until you install the firmware.
