This
is a typical view while testing the Ram chips on a Galaga video PCB.
Any of the Ram can be tested, by selecting a choice from the list in the
left.
In the following example, the 2114 memory chips at locations 3K and 3L are being
written to with a data value of '5'. This screen also shows the sequence of
events during the processing of the test request, which is useful in proving
that the test is being decoded and executed as expected. |
