hi. Is very hard! What are in upper slot? Have you some RAM or EPROM or EEPRON (in slot in up) ?. Best way (for me in the first) is connect whit PG/pc Station and see with software the message code. There are some table with acronym message after see the manual to relate the acronym message. Then if you want to post here the message error ! bye

Hi. ...Ram.. maybe but maybe the problem is there. maybe but maybe you need compression memory. Have you some news about cpu error message?! is importat! before compression memory. The Battery is good? Have you some back-up?. Some digital output are in on state? bye

Can you go online and check the Istack and Bstack for the cause of error?
