Went to power up our nakamura tw-10 today and control will not boot it gets stuck on the initial screen and shows

SYSTEM ALARM B103 - 18

972 NMI OCCURRED IN OTHER MODULE
SLOT 03
913 RAM PARITY : (4N+3) <SUB

i am wondering what to try, we had a ram parity error before and reloaded the entire system and it took about 6 month to get it up and running again. i am wondering lost or currupt parameters could causing the 972 error and if a complete re load will fix the machine. we have an rs232 backup but have lost the procedure to get this back in and going again. any help and or service manual for the 16T would be great its a 16-TTA control.
