2) Functional description
The keyboard test is performed with the sum check data of the key
code.
The sum check data is input into to the upper upper four digits before
the diagnostics code.
The data are compared with the added data which are added until the
final key (CA/AT) is pressed. If the data agree with the added data,
the end print is made. If not, the error print is made.
The sum check data is obtained by totalizing all key hardware codes
except for the (CA/AT) key and converting the total into a decimal figure.
