CPU Test - Introduction A CPU Test Program
Operating Instructions by SUPERSOFT
Command Line Parameters
: CPU Test
Command line options: disk log.
Test and features:
. Determine whether you are using a Z80 or an 8080/8085.
. Check the speed at which your CPU runs.
. Test each of the instructions that your CPU is able to
execute, check all results, and report any errors.
The CPU test ("CPU") interprets a program that is
designed to execute all single instruction sequences and
many multiple instruction sequences. After each instruction
sequence, the program tests all of the CPU registers to see
that the proper registers changed correctly, and only those
registers changed. This will detect, for instance, if
storing into the A register affects the B register.
: CPU Test Operating Instructions
1. In response to the system prompt, type "CPU". The CPU
test accepts the following command line parameter:
"LOG". If you wish to direct the output from the test
to a disk file then enter the word "LOG" on the command
line; otherwise leave it blank. You will see:

2. After the copyright notice the following line is
displayed:
ABCDEFGHIJKLMNOPQRSTUVWXYZ
Each character represents a short preliminary test of
the CPU. If this sequence is not printed, the CPU is
faulty, perhaps too faulty to give reliable results on
the rest of the test. Included in the preliminary
tests are tests of the jump instructions and various
other instructions that are crucial to the performance
of the test. Also included is a checksum of the test
itself. This helps to determine if the test is
residing in memory correctly.
: CPU Test Command Line Parameters
The command line takes the following form:
A>CPU [LOG]
Where
LOG: If "LOG" is present then the test output
will be logged to disk, otherwise all test
output will be sent to the console.
