Card Diagnostics Screen Definitions
This term: Indicates:
Start/Stop 1784-KT2
Processor (Z80 CPU)
tests results of the PS/2's ability to perform a software reset of the
1784-KT2. After the reset, the 1784-KT2'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 1784-KT2'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 1784-KT2.
If the 1784-KT2 cannot receive an interrupt from the PS/2, the failure
counter increments and continues with the next test.
Memory test results of the 1784-KT2's ability to read from and write to the
1784-KT2'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 1784-KT2's
counterĆtimer 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
1784-KT2's Serial I/O chip. If any errors occur, the failure counter
increments and continues with the next test.
