Hello,
This happened yesterday and this morning when the machine was not running. It is the first time ive seen this alarm. The alarm screen is not the normal one. It is totally blank except the message:

System Alarm
972 NMI occurred in other module
slot 02
930 CPU interrupt

then this morning it said the same thing except the end was
916 DRAM parity

the alarm clears with a shut down but Im assuming that something in the control is dying. either a cable or board? Anything to have the machine tech look at next time hes here? The machine is from 96' so its starting to hit that golden age of glitches
