Realistically, you'll need good 97 to troubleshoot, first at the board level and then down to the component as the problem is most likely a bad ROM 6 (1818-0230). You can troubleshoot using the instructions in the 97 service manual on page 4-2.
Note: The service manual only shows the component locations for first generation logic board layout, the second one, done for the 97S, is not documented. Further, the rom locations shown in figure 4-9 are not correct. The order from left to right is ROM 1,2,6,5 and 3 and not 1,2,3,4,5 as shown.
