Testing and Troubleshooting
After a est is run, you may select the option “SHOW STATUS” and see a
summary of usable memory (see Figure 3.3). The sixteen banks show 64K
for good RAM and 0K (zero) if RAM is missing or bad in the bank. A RAM
Group having 256K chips, where one or more 256K chips are “partially”
defective, will show only 64K available in that group.

Test Results
If one chip in a bank fails, the rest of the bank will be shown as there but not
useable. This is like having one flat tire on your car, the other three tires are
fine, but the car in not “useable”.
Several reasons may lie behind an appearance of a blank square or an “X” in a
square. If these results are shown as the result of your testing, write down the
socket number of those chips that test “bad.” Turn off the Apple, unplug it,
remove its cover, and remove the MultiRam RGB Card from the auxiliary slot
for better examination.
