2-1-3 Indicators
CPU Unit indicators provide visual information on the general operation of the
PC. Although not substitutes for proper error programming using the flags and
other error indicators provided in the data areas of memory, these indicators pro-
vide ready confirmation of proper operation. CPU Unit indicators are shown
below and are described in the following table.
