VERIFIC:A TION TEST
Overview
The verification program allows the user to make a fast check of the operation and accuracy of the
A -to-O card. The program gives either a simple GO/NO-GO report, or an optional detailed report on
the state of each channel. The floppy disk containing the verification program also contains a
stripped-down, execute-only Pascal environment that is bootable on any 9000 Series 200 computer.
I CAUTION I
Do not touch the test assembly once it is installed and
power is applied; you may alter the results of the
verification program, if it is running, or you could
receive a shock.
Loading the verification program
The verification program is run by inserting the floppy disk in the computer's boot disk drive and
loading the system, "SYSTEM_A", from the disk. When the system finishes loading it will transfer
control to the verification program liST ART A". There is no command interpreter, so if the verification
program ever terminates the computer must be re-booted to restart the verification program. Also,
there is no sub-routine to permit scrolling the screen back.
SEQUENCE
The verification program will ask you a few questions. Once the questions have been answered, the
verification program will test the specified A -to-O cards in increasing select code order, reporting the
results as specified on each card tested. When all the specified cards have been tested, the number of
test passes is: reported and the testing begins again until the number of test passes requested has been
executed. Then the verification program branches and asks "00 you wish to repeat the program (YIN)
?". If the answer is no, the program terminates, if yes, the verification program starts over from the
beginning. 'We refer to this question as the lire peat program question" in the remainder of this description of the program run.
