5.10.6.2 Test of data writing into FM
This test diagnoses the possibility of writing into the FM.
During the test, bytes '55' and 'AA' are written into the FM test
area. First writing of the '55' byte is at the address 1FF00 and
first writing of the 'AA' byte at the address 1FF40. Next test
shifts these values by one. There are maximum 64 tests pos-
sible.
Procedure:
Look up "Write Test" in the FM test submenu using arrows or
enter code 2 and press OK E

2.Write Test
Testing procedure:
1. FM memory is read for checking data and verifies them.
2. From the address 1FF00 (7FF00 for 512 kB version) the first
free byte is located and the value '55' is written there.
3. From the address 1FF40 (7FF40 for 512 kB version) the first
free byte is located and the value 'AA' is written there.
4. The test summary is both printed and displayed.
Printed testing output:
TEST 966.2
Note: If the FM testing area is full the ECR displays this fact
on the display.

5.10.6.3 Test of data reading from FM
The FM data reading tests allow the checking the data writ-
ten in the FM. Reading from the whole FM is possible or it is
also possible to read small blocks of memory (8 kB for 128 kB
version or 32 kB for 512 kB version).
Procedure for reading the whole FM:
