hello, We are looking for an older microwave manual. It is a GE Spacesaver microwave. Inside the door there is this number: 320C472P02. On the bottom of the microwave that is above the stove, there is a serial number ME601888?? I am not sure of the last 2 numbers. There is also a date of " Decembr 1990". Can you tell us where to find a manual? Thank you. Erin
