Very wise for such complex IC architecture involved machines! ; - )
Only way to go if planning to keep and rely on for long time
They getting old now and chips not so easy to find

Also keeping the power supply in good order, free of ripple, and voltages adjusted per schematic keeps these IC filled, technologically loaded to the brim wonders reliable and functioning as they should. Critical on these machines.
