I thought that the card on base 0 (A16B-2200-0129/04B) should be defective. So I replace that card, but I have still the same error. Power supply checked by scope, OK
When i go to Dump memory and look into the memory, I see strange data like:
FFFFAEA0
00AE 0000 00AE
00AE 0000 00AE
00AE 0000 00AE
00AE 0000 00AE
Could it possible that the data at some address is not cleared. Or is this patron normal.
I should thing there is something wrong with an address line?
Somebody who can help me?
* Error on screen:
F15TF A302A
RAM PARITY ERROR
Ram parity base 0
when I press RESET, I get this
PL
1 DUMP MEMORY
2
3 CLEAR FILE
4 SETTING
5
6 END IPL
* Master clear procedure:
I have all parameters backed up so that wouldn't be a problem;
I did a master clear like the procedure below:
1) Power up machine with "-" minus and "." decimal point depressed
2) Key "99" and "Input"
3) Key Password @ each "?" prompt and "input" after each is keyed
4) Key in "3" or whatever # axes in parameter 9100 @ "AXIS" prompt
5) Step through options by number and key new Hexadecimal codes and "input"
option 1=9100, option 2=9101 (option parameters gebruikt zoals op de papieren machine) ect. Just push input if no change is required
6) If "clear files" appears, hit "Y" - will erase programs etc.
7) When 1st menu appears, key "6" and "enter"
