Your NCR is encountered an ILLEGAL INSTRUCTION from the SCRIPTS processor.
INSTRUCTION is c1000004 which looks like a MOVE MEMORY with the
NO_FLUSH bit set. This is what the doc says.
Seems the NCR has been confused by some weird condition.
Could you give the latest driver version (3.0c) a try and report me
how it complains about the problem?
