Testing and Troubleshooting

At the end of a test, you will see one of three markings appear in each quarter

of the sockets (see Figure 3.2):

- A “+“ on a black background indicates the RAM in the 64K auxiliary

memory segment, whether found on a 64K RAM chip or a 256K RAM

chip, tested good.

- An “X” on a white background indicates the RAM in the 64K auxiliary

memory segment is probably good but can’t be completely tested because

another chip in the same group of sockets tested bad, was missing, or

was not the same size as the other RAM in the group.

- An empty square indicates bad RAM or missing RAM.
