I have a Tron PCB booting straight to a ROM error. No more information from the board. I reseated all ROM and EPROMs but to no avail. I reseated the ribbon cables which are pretty beat up though and will need to be replaced.

Is there any advice with the limited information that I have.
 
Check the +5VDC on the board. I have personally seen some finicky Bally MCR PCB's that boot up tp a ROM error when the voltage isn't spot on.

is it a ROM or RAM error.

i remember it being a RAM error.

the voltages have been verified and are good on the chips.
