We had exactly the same problem here, and it's in the software, not the hardware.

Line 2397345 most likely reads "IF 'LINE 2397344 => '0'' THEN GO SUBR 'LACY_69' ELSE GO SUBR 'SMOK' THEN END OR ELSE"

Not only should this read "=" and not "=>" because it refers to a truth table, subroutine LACY-69 is an incorrect mass of spaghetti code written in LITHP, a programming language which is little or no longer used. You'll have to either rewrite in C+++ or Java, or find a translator program which will first reduce it to machine language and then bring the machine language into either C+++ or JVB. Or ADA. ADA would work too.

Got that? No problem at all to fix, really.
