protects the equipment against damage caused by static
electricity.
The NTTR70 is in the right card slot in the upper left side of the TSS.
Note: Record the position of the DIP switches on the SMC card.
Set the DIP switches on the replacement card to the same settings as those
on the card you have just removed.
