This term:
Indicates
Start/Stop 1784KT2
Processor (Z80 CPU)
tests results of the PS/2's ability to perform a software reset of the 1784KT2. After the reset,
the 1784KT2's status and execution capabilities are verified. If any errors occur, the failure
counter increments and continues with the next test.
Dual Port (KT2 side)
tests results of the 1784KT2's ability to read from and write to the dual port memory. If any
errors occur, the failure counter increments and continues with the next test.
Interrupts
(PS2 to KT2)
test results of the interrupt capabilities from the PS/2 to the 1784KT2. If the 1784KT2 cannot
receive an interrupt from the PS/2, the failure counter increments and continues with the next
test.
Memory
test results of the 1784KT2's ability to read from and write to the 1784KT2's internal memory
chips. If any errors occur, the failure counter increments and continues with the next test.
Timer Operation
test results of the accuracy and capabilities of the 1784KT2's countertimer chips. If any errors
occur, the failure counter increments and continues with the next test.
Serial Port Operation
test results of the interrupts and loopback capabilities of the 1784KT2's Serial I/O chip. If any
errors occur, the failure counter increments and continues with the next test.
